I have a B&M FPR mod on a stock regulator... it's worked fine for a couple years... but now the car feels wierd, when I checked the fuel pressure, I pulled the hose and it read 48psi... I then clamped the hose with my finger and the pressure barely increased... not even 2 psi.

Would this mean my FPR is fubar ?

 

The fuel pressure also cannot be adjusted and I just found another thread in a search saying it's the B&M sticking open partially...

If it's not... lemme know... I'll be digging in my attic for a stock fpr.

 

sounds like it is time to pitch it.........

Trying cleaning it first, taking it all the way apart. Mine stuck open once, the day before a local import race. I was spraying at that time, I would have lost my motor.........

I went with Aeromotive rail mount, $180......

 

Haven't taken it apart to see what went wrong... but DAMN it was holding the engine back... stock FPR went on and I got back my mid range and tip in !!!

Oh... and dropped 0.3 off my last pathetic 1/4 mile ET... LOL

 

Yeah i got one of them too, it sucks ballz.
Mine would not move when i adjusted it at all, hose on or off.
Im gonna chuck it and put the stock one on as well. B&M Sucks!
