Default Fuel pressure regulator

Alright my truck is an 87 with the 2.9, is the fuel pressure regulator at the back of the lower intake and has a line that goes to the vacuum tree? i could smell fuel under my hood and it turns out there is gas in the line going into the vacuum system. just trying to make sure i know the right part

Default Re: Fuel pressure regulator

Yes, it's in the back, driver's side, on the fuel rail, just above the lower intake manifold; and it does have a vacuum line from it to the vacuum tap. Does sound like it has ruptured if there is fuel in it.

Edit, missed you post before,

as far as maintenance, especially plugs, wires, dist cap & rotor, fuel filter. Good to keep the fuel system clear to help the life spans of the pumps (yours has two). Heads are prone to cracking, I would recommend an aftermarket temp gauge. A flush probably wouldn't hurt. Oil change definitely. If it's an auto, install a bigger cooler in the front, and do a quick change w/ a new trans filter. Grease your sterring linkages, etc. Go over vacuum lines, make sure there aren't any rotted. Key to this engine is maintenance. EGR port is notorious for getting clogged up solid also in the upper intake.

Thumbs up Re: Fuel pressure regulator

Thanks!, yeah i called autozone they wanted 91 bucks for a new one, but i can get one through o'rielly auto parts for 45. that would probably explain it running like complete sh*t. i put a new cap and rotor on it. the old cap had the metal piece broke off where it touches the rotor, so hopefully after this small amount of maintenance and sea-foam it will run better. but the regulator was shot for sure so tomorrow i pick up my new one!
