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?

[oweban]

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.

thanks for pics cpd.

Whats peoples thoughts on getting new fuel hose? Would any fuel hose do?

[Aberax]

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

I tried installing mine today...i failed miserably . 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.

Thanks.

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

Last week when i tried, i tried doing in the same way as the third picture shows. Any help would be greatly appreciated, as my car is my daily, and i have work tomz.

[Luke_GTS-T]

hmm? just mount it as high up as you can, securing it with 2 hose clamps.

ok having trouble getting the pump cradle back onto the bracket. it seems like the 040 is hitting the bottom of the tank and wont let the cradle hook onto the bracket! HELP MEEEEE

[gumflapper]

this is what i did...

[Luke_GTS-T]

yer im having trouble gettin the whole thing to fit up bak to the cradle...

[Aberax]

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.

[gumflapper]

y did u need new fuel hose? i used the original that was in the car as there was nothing wrong with it and its been fine since december 08

[Aberax]

Cos i wanted to, also in case i needed/wanted to put the stock pump back in

[Djdirt]

ok just wann know,

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

[Djdirt]

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
