    Fuel Pump Suggestions

    Looking for a fuel pump!

    I don't have any insane power requirements for now, but I'd rather not upgrade down the road. I have stock injectors still and will probably upgrade to ID1000s down the road.

    I've seen some various remarks about various brands. It seems that walbro is kinda the staple as far as reliability is concerned.

    Any thoughts?

    255lph is safe for a ~20g turbo?

    I may turn the pressure up a tad bit depending a talk with ID, but I'm sure all the pumps out there will have drastically less flow with a higher pressure.

    The walbro requires a fuel housing modification, correct?

    Should be no problem... unless going with a 76mm compressor or something.

    Possibly. The new GR fuel pumps are a PITA to service.

    No need to turn the pressure up with ID1000s on a 20g, not even if you were running e85.

    I'm really getting sick of the site always crashing and double posting.

    I wouldn't do it out of need for a bit extra volume... but some injectors have much better atomization (spelling?) at higher pressures. I was just gonna check with ID when I get their injectors down the road a bit.



    Thanks for the suggestions guys. I'll do some reading to see if I have to modify the fuel pump housing or not, but will plan on a walbro 255 anyhow. Worst case scenario, I upgrade it down the road.

    True.. tho I would assume the spray pattern on ID1000s is going to be pretty good even at stock base pressure. The regular Wally 255 flow drops off pretty steep when you raise the pressure, but they do have a "high pressure" version. Or you could always get a pump that will handle the increase better, like an Aeromotive 340. But at that point you're over thinking things almost as much as I do.
