How many people use the B&M CommandFlo FPR? Any issues with reliability cayse it reuses the stock diaphram?

 

Ive used my B&M FPR without any troubles for the past year and a half I believe. It has never given me any trouble. The gauge on the other hand was quite bad. Since it doesnt have any fluid in it to absorb the vibrations it breaks quite easily. I am now using a marshall liquid filled. Got it for about $25 I think off of ebay.

 

on a boosted motor however i dont recommend using one...they arent 1:1...

really? what are they? what fpr would u recommend if not the commandflo for boost?

 

i recommend an aem...the b&m doesnt change the stock fpr much at all...you can just turn the pressure up thats all it does...

uh issnt that what an FPR does (Adjustable Fuel Pressure Regulator)

I plan on using it on my DD 400whp fi street car, think itll be ok? I already got a walbro 255 in there and with just the stock fpr (non-adjustable) my idle fuel pressure was around 45psi, seemed a lil on the high side...

edit: read some info on the aeromotive fpr and it states it raises pressure 1psi per pound of boost, so doesnt that make it 1:1 as well?

 

yes thats exactly what it means...however the stock regulator is only like .5:1 the aem is a 1:1

 

so your saying even with the b&m commandflo it only raises fuel pressure .5psi for every 1psi of boost? Even with the different spring?

Is anyone else running the commandflo on a fi setup? I just already have this brand new commandflo assembled and want to know if its worth the $150 to get a different one or if this will be fine.... if i were to get a different one i would go aeromotive...

 

?

 

im using a b&m and its fine.

 

ive had mine on for a couple of months seemed to be working fine until i put my walbro 255 in. it seems to keep the pressure around 40 psi no matter where the spring is adjusted at. is anyone esle havin similar problems with theirs??

 

dan, your a post *****, the b+m will work fine. you dont need a FPR that afjust fuel pressure per psi of boost, you just need a good tune on the stock FPR

 

I had the B&M for 8 years since '98.. After the car was boosted, I was still using the same B&M FPR, and right now I am still using it. So about 3 years with the car boosted and there are no problems.
