Well i just purchased a 89 Camaro for 400 bucks and its in really good shape concidering the price!!Well while going through it and checking everyhting out i came across a leak on the preasure regulater.everyone i have talked to has told me that it cant be fixed and that i have teither buy a new throttle body or replace the top half of it..Everywhere i have looked i come up short and i get the same answers,we dont carry them and we cant order them,,,someone out there has to have them so any help would be great!!!!

the engine is a 305 ,,,,,,,,,thanx

 

Is this a TPI car? Are you talking about the Fuel Pressure Regulator?

If so, that has nothing to do with the throttle body. As far as TBI goes, I don't have much idea, but try to clarify as much as you can to get the best response.

 

Are you referring to the golden cylinder in the back of TBI? You could buy a new adjustable fuel pressure regulator from cfm-tech.com. If it's the rubber seal only, then you can purchase a TBI rebuild kit to replace that gasket. If the metal weld has come loose and it is leaking from the bottom of the cylinder only then you'll need to get one off of a junkyard or from any other used TBI(Parts for sale/Parts wanted section of forums) It's only held on with 4 screws but has a high tension spring inside. You will have to take the top part of the TBI apart to replace the Fuel Pressure Regulator, and you might have to replace the gaskets. Half of my gaskets were cooked, half weren't. Hope this helps.

 

Thanks for the input,,im now ona mission!!!!!

 

your best bet is the junk yard, tbi units came on over 4 million trucks and cars they are really cheap from a year too. while your at it you might want to modify the tbi. theres a tech article on it. also make you fuel pressure regulator adjustable then you can turn up the juice later when you add power.
