BBK FPR

bbk and areomotive's FPR's do not hold fuel pressure, at all, when the car is turned off, this causes increased cranking time for pressure to build. I e-mailed both companies and they said it was normal, they said "if any thing it would help oil pressure build". I just did not like my car turning over 6-7 times before it started, or you can leave your ignition in the "on" position for about 20 sec then start your car!!! "NO" Kirban is the only one that holdes FP at all times. Go kirban

That is not true.

The fuel system will lose pressure with any regulator, including Kirban. Mine takes about 45 minutes to drop all the way to zero after I shut off the car.

And as for regaining fuel pressure when you start it, you should have full pressure as soon as the fuel pump stops running when the key is turned to "ON" -- takes about one second. If it takes 20 seconds, something is broken.

yeah, the +96 cars have the fuel return system which makes no fuel pressure after the car is off. ours holds it for awhile.

i had a problem with paxton (same as bbk but stamped as paxton) with it leakin bad. ive heard many problems with them. id spend a few extra bucks and get kirban. ive had mine for over 2 years and i love it. no problems at all

agreed.
note: i dont know what you guys have for sure but i assume it is like foxes.

the check valve in the tank is generally what is to blame for pressure bleeding off when the car is turned off (and bleed off after 30 - 60 minutes is normal and good - no need to keep full pressure on the system when it is not needed, since half a second of priming brings it back up to par).

i too would run a kirban.
 
I"ve got a bbk and i had a similar problem, i thought it was leaking, losing pressure, but it ended up being the bbk gauge that i bought with it on the fuel rail. The regulator really didn't have much of anything to do with it at all. Like they said, it's supposed to do that.
