Question about FPR's
Looking for some help from you e36 guys. I'm running an obd-1 m52 (21.5# pink tops) and have been chasing down some fuel mileage issues. I found today that the motor I bought had a 3 bar fpr from an e30 318is in the rail instead of the 3.5bar it should have. I replaced the fpr with a spare 3.5bar unit, but now I'm having a nice fuel leak out the fpr when I start the car.
The fuel rail design in my car uses a large snap ring to hold the fpr in, but the junkyard spare I had used a v-band design to hold it in. Is there a difference in the e36 fuel rails, and are these 2 types interchangeable?
This is the fuel rail type in my car
This is the fuel rail type my spare regulator came off.
Any help is greatly appreciated.
if you have a leak you're probably missing the o-ring on the regulator, or possibly there is an extra o-ring stuck in the rail.
I had both o-rings on the fpr, and both on the fpr that came out of the rail. I'm going to get some fresh o-rings tomorrow and see if that fixes the problem
