Fuel Pump Pressure regulator

I have 1988 f-150 4x4 with 4.9l engine.

Has anyone been able to replace the fuel pump pressure regulator without having to tear the intake off (I guess that is what it is called?) I was checking I think I can get some long Allen wreches into the socket head screws? Was just wondering if it can be done without taking everything off?

Thanks

yours too...

hey, i got your email and i sent a reply, but im not sure if i was supposed to reply to that address or not. anyway, i think i also have to do my pressure regulator, cause i also have a 4.9 88 f250 (2wd) and whenever i start it up it always stalls the first time. but when i start it again it keeps running. also i notice if i turn the key to run and let it sit for like 30seconds it will start fine. so im guessing it has to build pressure. who knows it might be the fuel pump? anyway whats yours doing? how do u know that you need the pressure regulator?

yes you need to take the upper plenum off the get to it. not a hard job, more time consuming.

I did it without removing the upper intake. I also R&R'd my injectors with the intake in place. It was a pain in the knuckles.

If you get code 11 then test the fuel pressure. Do you have two fuel tanks on your truck, does it do it on both tanks? 87 f150 4.9

nah i only got one tank. yes i do get a check engine light but i never bothered to check for codes. im not sure when ill actually get around to diagnosing and fixing this problem, right now its just a pain in the ***. actually the guy i bpught the trucl from said he owned it for a little over a yuear and he always had that problem. so it might not even get worse than it is. but thanx for the suggestions anyway!!!

Fuel Pump pressure regulator

Thanks for the replies I am going to try to get the regulator off without taking the intake off. I know the regulator is bad it has gas coming out of it where the vacuum hose hooks onto it.

Thanks again, Ham4ever
