Just got it in for a diagnosis at this stage and they found fuel looked very sus with most likely water contamination, said it looked like creek water. Pretty weird only thing I can think of is dodgey servo which could have been anywhere between Vic & WA. Anyway upshot is tanks need pulling out, draining and flushing, pump most likely needs a rebuild and injectors could be suspect too. Need to have a think weather is worth pursuing with this pump or just replacing with another unit such as UFI. Also obviously whole thing will not be cheap can do some stuff myself to keep costs down or look at insurance maybe. . .

Also thought oil feed was leaking on block but looks like one of the exhaust studs is leaking which needs to be fixed too. . . Ah the joys of tinkering with cars [emoji6]

Apart from that. Whats your thoughts with Cornells? I know they did wonders with my old SD33T I had years back.... Im soon to book mine in with AG Diesel, only because thats where my pump came from and they are close to work.

Yeah good so far, have been very up front about everything. The place is pretty impressive is absolutely immaculate and a pretty big setup. Apparenty AG sold the business and the new guys aren't as good but that was just one person's opinion so don't know bout that one?

Not sure if i feel dodgey or they would be s#itty if I got another pump and got them to install it. Would go UFI. Did mention it breifly the other day didn't seem too pissed off lol . .

Will definitely upgrade filtration after all this, the water sensor on the filter is the only thing that isn't hooked up as part of the conversion.

Sorry Rossco. This is terrible news. The fuelmiser water separator is very attractive after this. Very popular for touring and i see why if this is the end result.

I cant imagine they would care if you buy a UFI pump or one of theirs, you wont be the first person to do that.

Before you lash out mate, get the tanks flushed and all lines drained.

For sure pump has issues but would be interested to see how it performs after that first and maybe another tune and diagnosis.

Yeah maybe need to make some decisions Monday. Looks like this pump probably needs a rebuild at this stage which will be close to the price of a new pump. They're gonna quote some stuff up by then hopefully, see what happens. .

So bit of an update, tried putting in an insurance claim for fuel contamination but didn't go too well. . You need a receipt from where the dodgey fuel came from, who keeps fuel receipts and crickies knows where it came from have filled the thing up a zillion times halfway across Australia. . . Anyways got Cornells to flush & treat tanks which is good thing anyway add sub tank was a little dodgey from the days it was a dual fuel tank so good to get that sorted. Ordered a new injector pump from United which arrived today. . .

This is what happens when you work with your partner and they send it with the price sticking up on the invoice. . Busted lol .

She's snazzy can't wait to get this thing going. Assuming .65 - .7mm is the timing for it. Also glad I've got the fuel system sorted, will definitely sort out filtration for this thing too. What is a good system to use, don't know a huge amount about whats out there?http://www.nissanpatrol.com.au/forum...018/09/138.jpg
