I'm after fitting an after market fuel pump (in tank).

Has anyone done this and made or bought a flange, or did you go to the scrappers and chop up a tank to get a flange?

Thanks
Mark

I have an R1 in tank pump in my ally tank, just made a flange myself, then had it TIG welded to the tank

It would be a plan: there's a lot more bits out there for bikes, but I am planning for 250 bhp so will need a pump with the right cojones.

Same as cloudy. My c20xe runs from a gsxr in tank pump no problems. Plus its internally pressure controlled so no need for a rail regulator OR a return pipe. There used to be a good picture of one one big rich's car.

Here it is

What sort of horsepower are you feeding from that pump? A simples solution would be great.

I wish I'd mentioned I'm driving a duratec with this, specifying 250bhp.

I'm not sure a gsxr pump can delivery that flow.

Not sure how much HP I have.
STd 2ltr redtop xe with gsxr1000 bodies and injectors and ms1 v2.2 extra code.
Someone else on here had that sort of set up on a rolling road and it made just on the 200 nags.

I've found that I've got weber IW-031 injectors. I need to see what flow they're rated to at 80% duty cycle, then see if that flow matches what the pump can provide; I'd sincerely like to use that pump; cheap and already comes with a nice mounting flange, as well as regulating pressure to boot.

One option would be to take my 4 injector rail off and fit a pair of two-injector rails, running off two pumps, one each. Another option would be two pumps in parallel, but that would give me more flow for no more pressure (I think).

E36 M3 EVO pump sits in-tank and will do 5 bar, or the non-evo one will do 3 bar (still good for 290 bhp). You'd need a pressure regulator and return feed though.

I like the way they fit (would prefer a bolt in flange though) - pump goes in the hole, tighten the cap to compress the washer.

I'd need the opposing threaded end though; could be worth a trip to the scrappy. OR, I could get tube to make the hole, then make a bolt-in plate that fits over the top to compress it. I can see that working.

Thanks Rodgling. It would still mean a regulator and return pipe. Bearing in mind I'm making my own tank and want to fit a fuel cooler in the return leg it wouldn't matter.

I'm interested in the "in-tank bike pump" debate, as I now have some starvation issues on my Megabusa, and I'm considering a swirl pot (that I already have sitting in a cardboard box) versus the "one hose/one pump" solution.

Reading some Cosmick pots around the forum it seems to be the perfect solution, but I'm not 100% sure... The questions I make are "why this solution isn't used by default from the BEC kit car industry?" and if it's 100% starvation proof.


Thanks for replies and apologise about my english...


cheers
