what would be the harm in running the car with the vacuum hose removed from the FPR? I only ask this Question because with the hose connected i get a reading on my fuel pressure gauge of 37psi, and when i disconnect the vacuum hose it gose up to 47 or 48 psi and my idle smoothes out. so i just wondered if i could run the car like this(without the hose) until i buy a new adjustable fuel pressure regulator from summit next week.

 

The motor is suppose to idle better with a lower fuel pressure. That is why it is set up the way it is. I see no harm if yours runs better until you get a new pressure regulator. Just make sure there is no air leak.

 

do you guys know how hard it is to install the holley fpr?
i'm thinking of getting it but I dont want to screw my car up to he point i cant drive it to a shop if i screw up.


basically un bolt the torx screws and remove old put it in new? does anything have to be disconnected before i remove the old fpr?
----------
and dumb question but how is it adjustable? automatically? or wheres a **** to adjust?

 

could installing a new fuel pump cause the old regulater to go out. because thats what im thinking.

 

well fuel pump works fine so im not sure about that just yet.

 

the only thing about taking the fpr off a tpi is you need the security torx bits. and make sure you have an upper plenum gasket set laying around just incase you screw up the ones you have. the only pain in the a$$ about the tpi system is puttin the top part of the plenum back on the car and lining up the holes pisses me off everytime!!! lol just take your time and mark the bolts and put them in bags.
