Fuel Pump Upgrade

[Terminal]

I was going to replace the fuel pump in my stagea, however the cradle the stock one fits into is way too small for the Bosch 040 to fit. the attachements for the sock are completely different on both fuel pumps. What have other people done to upgrade their fuel pumps? I just want to make sure I don't wreck anything by installing either the wrong fuel pump or not mounting it properly

i haven't seen the cradle for the stagea but i have fitted (to my R33) a bosch 984 which flows more and has a hose end that will fit the factory sock using a tiny piece of 12mm EFI line and a clamp which voids fuel pick up issues with the 040. i have a DIY in the tutorial DIY section if it helps.

alternatively greenline/nengun have nismo/tomei/sard pumps which are very competitive on price once you factor in your time and labour.

Sard all the way baby

I might just sell this 040 then and get something else at a later date when I actually need a fuel pump upgrade.

the 040 will fit in easy, this is a pic of the 040 in the stock cradle from my stagea, i just used a hose clamp to secure it in and clipped it back in

dont waste money on these direct fit Sard ones etc the Bosch ones fit perfect

oh also a 040 doesnt have a sock on the end at all, the whole bottom of the pump is a metal gauze (sp?) so u dont need a sock end

this is the cradle itself (i think from memory the top half of the cradle i removed to allow the fitment on the pump)

Well that's the most helpful thing I've seen all day, thank you very much for that.

Not having a sock would affect how low into the tank the fuel can go before it can't pump any more? the sock sits quite low in the tank. I guess I'd just have to mount the pump in quite a ways.

Thank you for those pics, very very awesome.

No worries Leshy the 040 will work out in the perfect spot, it cant sit too low in the tank or u will be jamming the filter onto the bottom of the tank and restrict the flow. the position i have in that pic is spot on and only issue i can see is with the whole end of the pump being a filter its not as low in the tank and maybe with under 1/4 of a tank it would possibly not be submerged on hard cornering, but i reckon it would need to be pretty damn empty to do that.

my 040 is mounted on stock cradle 'as low as it can go'.

have no issues with fuel starvation below 1/4 mark. can drive deep into the fuel-light-on stage.........

mind you I didnt install it myself, but paid bugga all for the install and battery direct wire feed.

Well I closed the fuel tank up after getting frustrated with it, also I was seeing purple elephants. I'll have anotehr go at it next weekend and just cable tie the pump onto the cradle. thanks for the help guys.

I'd be using a hose clamp if u can as some zip ties rot in petrol after a while and u dont want a floating fuel pump If u want to use zip ties use about 4 or 5 so if one rots away theres still some holding it in position.

Best bet is to do it with as little fuel in the tank as possible so u can see what u are doin abit better, also make doubly sure the cradle clips back in properly and it cant unclip and slide up. It took me a few goes at clipping it on but eventually it was fine

good luck

Thanks for that, I wasn't aware the petrol would erode the zip ties.
