Fitting a CAV filter to TDi42

[Cuppa]

I'm thinking of fitting one of these to my car, in-line before the factory fuel filter.

65736 65737

Can anyone answer some or all of the following questions:

1. If you have fitted one to a GU with the same motor where abouts did you fit it? (pic would be good).

2. Why do the filter housings have two inlets & two outlets (Just to facilitate fitting in different situations?) & does it matter which inlet is used with which outlet?

3. What are the two bolts screwed into the top face of the filter housing for?

4. On the factory fuel filter which is the inlet - firewall side or front of the car side of the housing?

5. The easiest & most accessible spot I have to mount it is on the wheel arch on the passenger side of the vehicle (where the aux battery used to be). Is there any problem extending the fuel lines to the opposite side of the engine bay & back again?

6. Do I need 8mm (5/16ths) or 10mm (3/8ths) hose tails to screw into the housing?

1 - never done it

2 - Yes & No IE you can use any combination of Ports for single/dual tanks, single/dual power plants, in/out same side etc as long as flow is with arrows and any unused ports are blanked

3 - Bleeding the filter and holding the assy together so the bottom 1/2 doesn't fall in the dirt

4 - Dunno

5 - Functionally no but not desireable

6 - Depends on the housing thread size :-)

I have one fitted to the GQ as a replacement of the original rather than in series. I fitted it about 10 years ago at least.

Note the factory fuel filter on a GQ is on the passenger side with fuel lines from the drivers side over and back on the fire wall so placement on passenger side don't be an issue at all.

I gave just fitted a similar filter as a prefilter on the GUIV. I fitted in on the passenger side where factory ABS unit would be fitted. Might have a pic.wull check and post it up. I just extended the factory line before the filter over to the passenger side the back again to the filter.

No dramas at all.

Yes I think the other screws and bolts are for alternate figments on other vehicles.

[MudRunnerTD]

Sorry no pics! Surprised I didn't take any?? Odd! Normally all over that!!

[Cuppa]

No problems sealing relacement filters & priming them Darren? Have read some folk have these problems but the alternative of spin on filters with a glass bowl is ridiculously expensive.

[MudRunnerTD]

No dramas sealing them at all. I tell you though....Once i dropped the glass bowl while replacing the filter.....It DID NOT BOUNCE! I now have a spare in my rear drawers as a spare.

Even fitting it on the passenger side in the GUIV i then had to use the standard primer to pump up, across, fill the second filter, pump back and fill the factory filter and it did it with ease. I just left the hose off until it was primed like i always do. Pump it into a cup until all the air is gone.

[MudRunnerTD]

And to answer 6.

take the new filter with you to pirtek and test fit the barbs you need.

[nissannewby]

GQs also came out with the fuel filter on the drivers side...

[nissannewby]

1. Fit in the main line from main tank. Anywhere as long as its easily accessible for service.

2. Just multiple ports allowing for different mountings. As long as you use 1 inlet and 1 outlet all will be fine.

3. As et said the bolt closest to the mounting flange is the bleed screw. The central one holds the assembly together.

4. The factory fuel filter head has arrows on it. But the one closest to the battery I believe is the outlet.

5. No problem but you are adding quite a bit of line to the system. You could mount it on the drivers side where the lines come up over the coil tower. Have seen a few mounted here attached underside of the tray.

6. Use the largest one you can fit. Make sure the id of the fittings is also larger between 5/16 and 3/8 some cheaper fittings wont be.

yeah by 1992 was on the Passenger side, not sure what year they moved it over the drivers side. I have just moved mine on the GQ to the Drivers side attached to eh side of the battery tray.

[MudRunnerTD]

couldn't be bothered culling all the rest of the quote out but here is the CAV filter and the move i made on the GQ.


Ok been busy under the hood over the last month. I am getting a few things sorted while it's parked up. I am getting it ready for a bigger airbox and hopefully a stainless snorkel through the bonnet at some point.

I have moved the Fuel Primer pump and the vacuum tank to the drivers side and stripped a heap of other crap off the fire wall. I removed the clutch bleed hose and tube and replace the hose and block to allow for the removal of the extra bleed.

This is a Big Job and will take some nutting out to put Humpty Dumpty back together again but it's getting there

Before.

5211552116

Fuel primer now attached to drivers side battery tray just above the fuel pump. The copper fuel pines across the fire wall are gone.

521185211952120

I relocated the vacuum tank and used the copper tube as the primary supply to the tank rather than from the tank just to the clutch

5212152122

Getting there

5212352124

Stripped out the clutch bleed valve as it's pointless. Phill at the 4WD Shed sells a replacement hose and block without the bleed for the win.

52125

Removed the redundant dual battery solenoid and wiring and pulled back a few wires that were no longer being used.

I am going to move the fuse block and have to remount it and sort out al the accessories that were going to the second battery that no longer exists. A bit to do yet but it's coming together

If you're fitting it in series with the factory filter, use the same size barbs and fuel hose.
I'm also thinking of adding one of those and I currently have a lift pump which is recommended if you're running 2 filters otherwise the pump will work harder to suck through both filters

[macca]

Cuppa used a piece of angle aluminium to mount the CAV. A small piece is bolted to the flat that you see in the photo (2 bolts visible)

Also fitted an outboard motor primer in the line from the tank to push fuel into the filters.

On the OEM filter the hose on the firewall side is from the tank, that has been extended (see brass joiner) through the bulb primer to the CAV then back from the CAV to the OEM filter.

If things go all wobbly the line from the tank can be put back in its original spot and away we go... I hope!

[Cuppa]

Thanks Darren & Matt, both very helpful ............ & I'll buy a spare bowl!

I guess it's safe to assume that the 45 litres per hour max flow rate that the 296 filter has, in conjunction wth the factory filter works ok with the pump I have.

[jff45]

I thought the bowls were made from a polycarbonate now so pretty hard to break.

Your pump will work harder as the filters start to clog. A lift pump also resolves all the priming issues.

Makes so much more sense!! My spare is also glass but again at least 10 years old.

What , where, how... can you give us a bit more info on the lift pump set up you have.

The set up I have has been on my Patrol for 6 years and 110000 klm, its working fine. Not sure now ???

[macca]

Might be a bit clearer Cuppa.

[Cuppa]

Thanks Macca, all clear now. I'll be doing as you've done, except will utilise some 3mm ally angle I have. Much better than going over to the other side of the engine bay. Ordered all the bits & pieces online this arvo. Now have to wait for the postman.

For anyone else considering fitting one of these filters as a 'pre-filter' ........ my main concern had been around the potential for a saga with priming each time the filter was replaced, but utilising a priming bulb as Macca has done will deal with that very well. Be aware that whilst there are plenty of cheap priming bulbs available, not all are suitable for for use with diesel.

I also read elsewhere where someone had written with certainty that the fuel lines on the TD42 are 10mm. Just to be sure I eased the hose part way off the factory filter housing on mine & measured the hose tail diameter. It was 8mm.

[MudRunnerTD]

Took a couple of pics earlier and just getting back to the forum now.. Looking at the way you mounted it Macca I reckon there would only be maybe 500mm of extra hose mounting across the bay. Either way is all good though.

Here is the mounting position I used on the GUIV.

Thanks Darren, it looks good, but I'm envious of all the space you have across your firewall, mine is far more crowded mainly due to my extended coolant system. I would have to take hoses underneath the intercooler, over the top of the rocker cover & & in closer proximity to the turbo than I'd like. None of which is probably that good for a fluid which in part acts as a coolant for the pump.

I'm a bit envious of your spin on filter too. However the reason I went for the cheaper CAV type, at the cost of less convenience when it comes to changing filters , was a story recounted to me by a mate who picked up some dirty fuel at a remote outback community. He was clogging filters in his Oka at the rate of around 100kms per filter for 6 filters before the remaing fuel was eventually 'clean'. He obviously carried a good supply of filters with him, easier to do when they are $7 a pop, (& replaceable at any small town which has a grader or a tractor). Horses for courses.

My new filter housing arrived in the mail today & the bowl is glass, as is the spare I bought. Got it online from Wagga Tractors - excellent service.

What filters are you referring to at that price?

The Donaldsons for my Brunny.

Just to be clear, I was replying to your post about Wagga Tractors confirming that I have had great service from them.

I also use a mob called WA Filters at almost exact same pricing and usually go with whoever has stock if the other Vendor is out.
The filters I need are an odd size as I think the Cocky who had my Brunny put them on as they are common to his tractors or trucks or whatever.

does he also do Oil filters? He should come on as a Vendor Sponsor, i reckon he would do OK as long as postage did not wreck it.

[Kimbo63]

Yep any kind of filter he can do it will have a talk to him tonite regarding vendor sponsorship never crossed my mind before
Thanks Darren

No problemo - it'd run it's course & if we get a forum vendor with good filter prices it'll be all to the good.

[Cuppa]

Filter is all fitted. Does it look familiar Macca? When I removed the feed pipe to the stock filter & heard the fuel gurgling & draining back to the tank I thought I'd be in for some fun & games re-priming the whole shebang. Was no problem at all though. I reckon Nissan should've fitted one of those bulb primers to every Patrol, they are so good. 3 or 4 gentle squeezes & the new filter was filled & a couple of pumps on the original pump was all that was needed. Car fired up no problem. Worth fitting even if you don't fit a pre-filter I reckon.
