fuel pumps need to be kept primed?

[Jacob]

Hey people! I was looking into a cheap upgraded fuel pump. I can get a mk4 tt pump for under a 100 shipped. I heard/read that they can hold my planned 500hp .. . I think I need to bump the volts up with a resistor (stock 12, needs 13.5-14).

Anyway, my question is whether or not fuel pumps need to stay primed when you take them out and store them.

Cheers,

tough to say, I've taken apart an old (and I mean OLD) fuel pump that still had fuel in it and the seals where disolved from the fuel.

on the other hand they could shrink and become brittle, ect...

Get a walbro 255lph with the install kit for like $100 shipped as well.

MK4TT pump is good as well...

You can't increase voltage with a resistor there bud.....

Thanks bro, I read something somewhere awhile ago. I guess I will have to reread it again. I remember how I guess just remember that you can increase the voltage.

This is a likely a USED mk4 pump as new they are aver double that price. I would suggest a NEW pump as opposed to a used one.

This test compares a MK4 TT pump versus the high flow walbro. The supra pump sucks about twice the current as a Walbro, so upgraded wiring is advised.

looks like walbro is the pick then thanks for that JPEG

I actually got the Walbro Verdict from some other people as well and ordered one. My current setup wont need more than that and it's cheap. Thanks again.
