Great write up. I wish this was up before i did mine. Did you use petrol resistant hose and wire? You wouldn't want the petrol to eat away at them.

I've got the thread saved, so I'll upload them all in this post.

I did this but didn't sit the bracket down properly, oops. Does anyone else have quite a loud pump noise when turning ignition to ON but not turning the car on just yet? Heh. All good.

^^Awesome

I was gonna upload some pics when i do mine, but no need now, i shall still take some though.

Just a question about the install. Once i have installed the fuel pump, i don't need to change anything else, such as pressure's, injector duty cycles, etc etc. It's just install and go?

If you're still running stock ECU/FPR/injectors, no, I'm pretty sure it's all sweet.

I'm having the Adaptronic ECU installed at the moment, and I don't think it needs to adjust... but when I upgrade my inj/fpr/turbo, I'll have to make modifications to the flowrate.

Any fuel hose should do, just make sure it is the right size.

I tried installing mine today...i failed miserably :D. I got the pump onto the bracket, but when i went to install the pump into the tank, it wouldn't go in, like it was too big or something. Could it have been because i hose clamped the pump to the bracket? the pictures above just show the fuel pump just hanging there, is that right?

I used a metal ring clamp thingy to attach the pump to the bracket after cutting it, and it fits fine ;) Just gotta wiggle it around a bit.

And yeah, new fuel hose is good; just get stuff the same size, it's fair cheap.

Turns out I had a Walbro GSS 341 in there; now sitting here doing nothing :)

For wiring sake. Is the wire with the green stripe on it positive or negative? Im replacing the terminals now and forgot to take note of which way they went.

Thanks.

Likewise :) . The solid red cable is Positive (+), the red cable with line (grey/green, cant remember) is Negative (-).

I fitted mine the other week...only lasted about 500k's, the pipe i used was wrong and melted and the pump wasn't secured to the cradle. So the pump fell into the tank, and the car broke down, had to leave it in a maccas carpark for 2-3 days.

this is what i did...

Luckily my boss had installed a few of these before, he fitted it like you have shown. However i am only using 1 hose clamp (bottom one), i also got some new fuel hose from Autobarn. I also found that for me, the pump went in with the hose clamp tensioner/screw at the back of the cradle, so the opposite side to what you have.

when mounted so low does this cause any issues like hitting the bottom of the tank as mentioned above?

and

Why are you guys not concerned about not using a filter/sock?

cheers

and while i am at it, these can be mounted in tank but these are "push" type pumps does this mean you gotta have 1/2 a tank to work/

and is anyone running these in tank without any surge tank setup

sorry about all the noob questions

      Front tower strut brace options

      By iamhe77 · Posted

      Anything for a 2003-2005 G35 will fit an M35. Just be mindful about clearance if you're running a plenum spacer or runner spacer.

      You know how I know I'm getting old? Because I feel this quote jells with me and SAU Forums, ha ha ha. I've gotten lost a few times as I had muscle memory to scroll to where I wanted on my phone and just click, now I'm lost... Ha ha ha     "I used to be with ‘it’, but then they changed what ‘it’ was. Now what I’m with isn’t ‘it’ anymore and what’s ‘it’ seems weird and scary."

      Rb25 into r31/wont idle

      By MBS206 · Posted

      You don't lose spark if your battery isolator isn't wired correctly and the ECU still has power from the alternator.   Car has an epic wiring problem. Sounds like power connected really really badly in places. Possibly a power pin on a ground pin for the ECU, and constant power in locations that should be switched ignition.   It needs someone good at diagnosing electrical, a good multimeter, and someone with the wiring diagrams to match the engine loom that has been put into the car, and wiring diagrams for the body side of things from the car.

      Front tower strut brace options

      By PNM35 · Posted

      Hi folks, what options exist for PNM35 or what models share the same dimensions and fitment for the front top of tower strut brace. I have seen a few options pop up through Google, the Ultra Racing Australia for one. I have seen some eBay ones that claim they fit C34 and M35 but can't find details if to work out if its true. Also found Taiko / TEMA4x4 claim the one type fits: - Nissan Stagea (2-nd gen; M35) 2001 - 2007, - Nissan Skyline (V35, HV35, NV35, V35, PV35) 2001 - 2007 - Infiniti G35, G35X (3-rd gen; V35) 2002 - 2006 But not sure how true that is. Anyone fitted one or know of someone using one and can confirm what does fit?

      AC Compressor

      By Butters · Posted

      I got the full kit.   The compressor as above is much smaller and lighter.  Also quieter. Bracket is visually mint and much lighter. The dryer and heat exchanger(rad) are one unit. Also smaller and lighter.  Much more room for an oil cooler. The fan I got was a bit Meh and I might change it.   And above all else it is more efficient, tested a good 3-4 degree's cooler than the old system, which is a lot. Disclaimer though - It wasn't a back to back test given different days. It really does feel colder though(always).  And this example is in my car with that crusty looking old compressor, not new vs new
