After years of the occasional high pitch whine, and the fear that the pump was going to die, its finally on its last legs. When I turn the key to ON now, its just a low pitch gurgle for a few seconds before the relays kicks it back off. Cars running lean and misfiring and its pretty undrivable now.

So now I need a new pump. Should I just get the Walbro 255lph HP again or should I get something bigger. Ive heard bad things about the Walbro but mine was doing just fine for a T04S 60-1 and 12psi. I do want to run some more though..

Should I get the Denso pump? It does flow more than the Walbro, right?
Has anyone installed a denso pump in an FC? I know a lot of FD guys have them.




If this has all been answered before, Im sorry. I tried searching but couldnt find anything that was really helpful.

 

yeah, first I'd say
FIX YOUR SIGNATURE The maximum lines allowed are 10 without an image and yours is 23 lines. Fix it before an admin sees it and deletes it.

then 2nd, I would say go with the Denso, I have personally only seen crappy Walbros that fail if you have the least amount of dirt or low gas in the tank. Only use the Walbros if you always keep at least a 1/4 tank of gas in the car at all times.

 

how about a Supra TT pump?

 

Supra pump is a Denso

 

And the denso pumps do flow more than the walbro pumps, right?
