I did one of these mods only a few weeks ago to my nav as i thought i was down a fair bit of power when i was out wheeling about a month ago. Mainly to see if this would improve power delivery a bit. I spliced into the lines from the fuel tank and used rubber lines from the steel bunting to connect to the new low pressure lift pump and back and a brass y piece in each side with a one way valve so if i ripped a wire off while out popped a fuse it should hopefully suck past the fuel pump. What i noticed after fitting the pump power improved throughout the rev range a little bit and idle became smoother but the motor was noticeably louder i suspect the pump or the injectors or both are a bit warn and that supplying a slightly pressurized fuel to the pump now has caused either a slight increase in fuel delivery or timing for the resulting increase in power and torque and maybe a little higher boost level measured on an in cab gauge.

I would still like to find where the rest of the ponies are missing from but haven't checked out much more then earths, connections and ecu codes. One afternoon when were quiet at work i would like to run it on the dyno and check air fuel ratios and actual power output to confirm that it is down(car has been on a few dynos and i no what it should be close to).

SO hopefully this is an interesting review for you to read and please get back to us with anything else you do to your car to get some power back to it as i would be keen on some other tested input with the car and what the results were for your lift pump install.

Also on a side note carrying out the spill line mod i found the fuel line to be a unique size and was quite hard compared to the other rubber lines i would factor in the cost of replacing the whole rubber hose to be safe shouldn't be too much i had trouble clamping the line at the ip inlet and again trying to get the hose onto a small brass T without it being loose, ended up using 1/4 inch barb and a considerable amount of hot water/ silicone spray to get them all on.

Howdy all, grate post.. I am planing to do a diesel cooler on mine - new pump or not... yes, do go read the 4x4patrol forum... some brilliant ideas and some very nice rigs..

Well i never knew about the spill line mod, missed that one.. i brought a 6mm and a 4mm brass barbed conectors and had Wide bay hydrolics in Gympie braze them together in a weird arse "y" piece..
Also had them weld up the "in " bango fitting...
New hose lines trough out to come... waiting on delivery 😉

Now regarding a diesel cooler , I'm allllll for it ! .

Anything to help these pumps... I was planning to put it on the return line up under the tray with a fan..

I was thinking an alloy one, solid with radial fins but now thinking trans cooler with fan.. next project whilst i try to work out the issue i have with a " no start" ...

It's a bit tricky trying to get "AN10" fittings that reduce to 4mm lol might have to call on wide bay me thinks!

Being that i have the standard tank and i want to try for Alice then Darwin back down to perth, i think it's a must do!
Yes, I'm scared shiteless about braking down now... The only thing good to come out of this is the knowledge and confidence of how to work on these motors and electrical sensors etc
I hate to think of the mechanics bill trying to fix this no start ! Lol or a nissan stealers, it would be in the thousands by now... I'll post pics when I start on the cooler.. cheers

fuel return lines are 8mm.

a transcooler is the easy option for a fuel cooler as they often have barbed fittings rather than AN. if you go radiator style just watch where the outlet is. it needs to be on the high side so air can be pushed out. the long windy tube style don't have that problem but are less efficient.

i doubt you need a fan.

you might have seen my old posts on the patrol forum about the spill line mod.
its typically done for fitting a diesel lift pump rather than heat.

Yesss, woops- i meant the spill line not return line.. the one from the bango bolt in the head to the pump, that's the part number i supplied.. Amayama parts for that one $ 20 wanna hear what nissan gympie wanted lol myyyy god...
Oh and yes i do have a lift pump, one of my first mods along with another diesel filter... wish i could access my original profile on here?

Regarding fan, yeah I had that thought also! Maybe fit it with room for one if needed.. i think I'll go that way , thanks man..

Finding a trans cooler with barbed fittings is a little tricky, i was looking at new ones but i could try the wreckers.. the ones i have found have the AN fittings, I'll keep looking..

Yes mate i see you're everywhere lol good job.. thanks for passing on your smarts man! When i get to nz the bears are on me... or keg, i like a keg!
Sounds like a utube post, two blokes and a keg...
It was that post on the patrol forum that got me onto the mod...

Yes , and you are right "I think" with what you stated on the pootrol forum..
Why he fitted it like that was out of convienence me thinks, smart bloke don't get me wrong, but he was wrong about the return line causing resistance and bleeding the air out, nice case of wishfull thinking there ;)
Sure it doesn't matter on the return line but as you say, the cooler could/would be doing half the job..
Once agian man, thanks

Just an up date, the cooler i was looking at had AN fittings.. The reason i was looking at this type of cooler was of the fabrication, had it own alloy shroud and mounts. Easy to mount buuut danm tricking and ugly getting 10mm down to return line hose diameter, so went tweak'e way and went with the trans cooler. Shity'er to mount and protect but having the barb fittings makes hose reduction muuuch easier.. wanna see some pics of camp site/farm shed fabrication?
A bit from bunnings alloy section, pop rivets, micro cutting disc and this is what i came up with..
Aaaaand before you going giving me grief , it's not done yet. I have gaurds and shrouds to go, this is just the mounting of the trans cooler lol... yup mk2 ;)

Anyway there it tiz- roast away gents ;)
