Efi upgrade

Nice work pezzer. Hope both vehicles start first go.
How did you go removing the branch spigot from the efi system? I've got a spare lying around, will probably replace mine in the near future.

Once I had the replacement I cut the original so I could use a 24mm socket and bar and it cracked instantly, to refit the new one I had to remove the bolt securing the Auto gearbox dip stick and twist it out of the way. To get a good seal I wrapped pink gas ptfe tape around the threads, job well done. I have now pulled the dash from the Maverick, much easier after removing the Patrol dash learnt a lot. tomorrow the complete loom will be removed from the Maverick. Still need an Idea for an external fuel pump as I do not want to pull the long range tank out to access the original.

Wiring loom transfers complete started plugging up so far only non compatible plug is 1 of the front door plugs both sides, and Patrol has an extra sensor in the radiator.

Plug up continues, the steering pump on the Patrol has a plug on the side where as the Maverick does not unsure of what this does maybe a level sensor. I will connect the battery before putting the main dash frame and front grille back and check what I can all the parts to fire up the now carby Patrol are in place except for the wiring from the gas tank of which is also being swapped.
Hoped that someone would of posted me info on an external pump to use with the Efi on the Maverick, no seems to have commented on this forum for a while.

Sorry pezzer, have been reading but not posting. Unfortunately I don't have an answer for the external fuel pump setup you're after. My power steering pump has that sensor you speak of, but the wires have broken off. Hasn't had any effect on running performance, might be just as you suggested, a level sensor.

Oh that's promising news as I do not want to swap them over. Went to hook up the throttle cable on the carby but found that the efi uses a longer one so I had to swap them over, easy with the dash out. I think that I will use the front door looms out of the Patrol saves cut and soldering, I will have to make a bracket to suit the ECU and locate it in the passenger foot well as was its position in the Patrol. I might look at dropping the Long range tanks on both vehicles, just hope the one in the Maverick has a cut out for the ion tank pump?

Okay today dropped both lpg tanks, and now have access to the rear looms. I managed to feed both looms back and over the rear left hand wheel on top of the chassis only to hit the next problem on both vehicles., The patrol has a lead going across to the Long Range fuel tank I believe this is to the relocated in tank fuel pump of which I am hunting for. BUT whom ever installed the tank used a nut and bolt (14mm) through the chassis with no access to hold the bolt with a spanner etc, so tomorrow off to a Fab shop and get someone to heat a spanner up and bend it in the hope that this will hold the bolt from spinning. Oh yes had to drop the Towbar to access the lpg tank cradle.
The Maverick, how handy is the 50mm lift to get access great. BUT this lpg tank has been plumbed up with copper pipe, and has been run behind the rear chassis cab mount, this in turn prevents the loom with plugs being pulled through, so now I need the free a stubborn nut on the body mount and raise the cab with the jack whilst the loom is removed. The next step is to strip the fuel pump leads from the Patrol loom and unite it with the Maverick loom and then reinstall both looms, The Maverick Long Range fuel tank is yet to be dropped, just hope it has an access for the pump. I will then refit the gas tanks, whilst swapping filler necks as at the moment the Maverick has an under body filler.

Just a quick note wiring crossing the chassis in front of rear diff is not to the tank as first thought its to the rear sway bar release unit. Bothe fuel tanks on each vehicle have the same aperture for pump and sender.

Today re making the rear looms shortening the Lwb and lengthening the shorty. There were 3 differences in the looms firstly the Efi loom has pump and sender in the same plug Maverick sender only, Efi loom has sway bar Disconnect ( still uncertain wether to move this complete unit over as there is nothing hindering access to it with the tanks out etc. Lastly the rear Efi lefthand light loom (not bumper lights) has only a 6 pin plug and a 4 pin plug where the Maverick has an 8 pin, on checking the colour codes I found that the 6 pin had a Purple with white trace where the Maverick uses Pink so I decided to colour match with the Pink from the 4 pin plug and have left the Purple wire along the new loom just in case. I have re run all wiring from the Lpg tanks to the heaters (the Maverick only had a hand valve to shut off the tank, whereas the Patrol has an auto cutoff), hence the swap.

Next problem the Patrol tank with the in tank pump has an extension piece attached to the tank to allow for the extra 50mm of depth on the unit. My intension is to remake the pump and sender unit shorter to fit into the Maverick tank with out having to have the tank welded. The Patrol fuel tank has be re fitted with the Maverick sender unit and relocated back in position under the vehicle, best chance to re run the new made up rear loom whilst the Lpg tank is out.
