OK so any of you that know me know i have had issues with my car on boost, these were all boiled down to fuel delivery issues.

my car was cutting out round corners and running lean on the dyno over 5000rpm, anyway the culprite was my BOSCH 040 intank fuel pump, it was extreamly clogged, the mesh cover was caked and the filter was clogged, so i replaced it with a new one.

this one has been in my tank for about 2 months and it has fallen to the same fate, unfortunatly the Bosch pumps do not have a servicable filter and i assume the internals have been damaged anyway as the pump has become noisy again.

so im going to replace it AGAIN with something different, just for funzies. anyway obviosuly my tank still has shit in it.

i could get the tan kcleaned and try again but i am sick of going through pumps. i do not know if its just debris in the tank or if its rust from the old tank. SO

i have sourced a GTR plastic tank W straps, i still need a sender,

1st question......

with the larger GTR tank and new sender unit, what is involved in getting this to work with my stock guage?

i have also sourced some new gtr injectors (i already have these installed but they might be farked) new ones have been flow tested and cleaned....

what else appart from the fuel filter should i replacein the fuel system? any lines, any bottle neck which may have been affected by the crap going though my system?

Are u sure crap has gone through the system or just in the pumps filter and possibly fuel filter?

Mates 34 did the same thing. He ran the fuel in the tank through a fuel filter and into some jerry cans a few times to remove the debris from the tank. Hasnt played up since

well i have destroyed 2 fuel pumps, while i have half the system out i might aswell replace anything else i can, dont want to lean out pushing 1bar boost at 6000rpm again, bad sensation when it chokes

No offense but that

Seams like the worst answer. I'm happy to get a new pump and tank, do it properly, I'm even getting cleaned and flow tested injectors incase their not %100, why would I just keep going through pumps at $200 a pop and get rid of filters? I don't want old tank crap getting past the filters I want their to be no crap.

I have a R34 with the same issue as the OP - Except I've gone through pumps in as little as uh, one day.

I was able to take the pump out, clean the mesh with it (Bosch 040) and put it back in and suprise suprise, it actually worked...

...until today, where it is again groaning and carrying on.

The above solution from Jez sounds like it's something to try, at $200 a pop, I can't afford a new pump every couple of days, but I CAN afford to buy like five fuel filters and some jerry cans and pump the tank through them and rinse/repeat instead of obliterating the mesh in the pump and killing pumps over and over.

Just cut the mesh out the bottom of the 040

Pump

And Just replace filter a lot more often.

While this sounds like the ultimate backyard fix, um.. would this actually work? Any thoughts? Its much, much, much easier to replace a filter in the R34 than the pump. (and especially the tank)

How often is often? 5k kms? Or is this option just madness?

Happy to do either or both, really, really tired of replacing fuel pumps.. twice a week.

Seriously. It is an utter bastard on the R34. So much so I'd almost rather spend $1200 on fuel pumps lol. I'll try the filter and jerry can thing and post here just incase some poor soul has this problem and searches the forums and finds this (like I did)

I removed the mesh on 040 worked well for me

No issues I did a filter on every service

5000kms

Just comes down to what your prepared to do

I cut mine off as I got sick of pulling pump to clean it.

Dare I ask what the best way of removing this is? I tend to replace the fuel filter when I replace the oil filter anyway (i.e every 5k kms), because it's .. right there, and costs like $10.

I've only cleaned the pump out, but never really attempted to cut the mesh.

Cant' you flush the tank while it's in the car ? Pull the lines out the bottom and bung up. fill the tank with a suitable solvent (I'm going to say ethanol) - but REMOVE the fuel pump first !!!!

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
