I did a search and got mixed answers I have a walbro 190 lph & a 255lph which is the best to use? i will be doing a lot of city & highway driving and i dont want to go too big if its not nessecary because i heard too big of a pump will over-work the pump and cause failure my setup is a
d16z6
ihi5 turbo @ 10 psi
450/ turboedit
goal hp 200-220 whp

 

run the stock pump and sell those two, then put the money toward gasoline, that ***** gettin expensive

 

I've never heard of "overworking" a 255lph pump on that type of setup. You have a return on your fuel system, so your pump does its thing, and whatever fuel isn't used goes right back in.

I have a 255 right now, I'm not going to be boosted for a few weeks, and it's working fine for me.

Someobody correct me if I'm wrong, but I don't think you'll have a problem with any of them.

 

Out of those two, the 190lph, 255lph is overkill.
Interested in knowing what a stock d series fuel pump can handle though.

 

bump for more answers

 

I am running the stock d fuel pump and injectors at the moment at 6psi.
No fuel starvation, but I bet I am pushing the limit.
