Fuel Pressure Regulator: Question

[Onefast99gsx]

I Found this on another forum: By the sounds of it, the 1g regulator might be than my 2g one anyway. Even if my regulator isn't bad.

From dsmtuners---

Does anyone happen to know if there will be any problems running a stock 1g fpr on a 2g? I only did this cause my 2g regulator went out and was leaking fuel, so I had an extra 1g one laying around. Long story short, i got the 1g regulator on and the car runs just fine... no leaks or anything.

Correct me if im wrong, but doesnt the 1g fpr have a lower psi rating? If so, wouldnt that be better if you had a larger pump, ie 190lph?


Somebody wrote back and said:

yes it runs 38psi instead of the 2g 43psi. but thats not a whole lot of diff it wont hurt your car any as of right now. but you will want to bet a AFPR in the futrue so u can turn it back up to 43psi.
