what is the difference exactly? specific situation here is going boost, using an AEM FPR and dsm 450s with a VAFC. so...the fpr just makes sure that the fuel being delivered to the injectors isn't at too high of a pressure. so is there a benefit to the high pressure fuel pump or not? is it kind of a range situation, where the HP version is just build sturdier so it can handle higher pressures, or does it deliver it at a higher pressure all the time...?

and don't just say higher pressure is better, because you'd be wrong.

anybody?

 

bump.

 

I switched to a walbro because my pump was 16 years old.
Considered it preventative maintenance.
I heard honda fuel pumps were good to 50 psi.
Hondata says 75 psi. Thats new to me.
You will be running higher pressures all the time.
I installed this on an 88 dx hatch w/b16.
I saw 8 lb increase in pressure.
I've heard the walbro is good until about 70 psi.

i'd say the benefit is going above 50 psi safely.
Do have a fuel pressure gage? If you don't get one.

 

sorry if i was unclear, i mean what's the difference between a walbro high pressure fuel pump and a walbro fuel pump. maybe if i put that in the title i'd actually get some responses...
