Need a little help

[Seankanzig]

I just replaced my AFPR, this past thursday and set the fuel pressure to 40psi. After replacing it, the truck want to die when you put it into reverse. It didn't do this before I replaced it, do i need to pump the fuel pressure up a little bit more?

Thank you,
Sean

Did you reconnect all the vacuum lines correctly?

Re: Need a little help

I think so, where is the vacuum line that runs from the fpr regulator supposed to go?

Thank you,

Exactly, you must have reconected something wrong, cel phones with cam are very usefull when doin it. Thats how i did my 20G and it still runs like a dream.

hmmm,

I need to get my hands on a vacuum diagram i think, because i think the vacuum line may be going to the wrong place :/

Long story short i pulled a little hard to get the vac line off the afpr so i'll check it out monday when i go down to mess with my truck.

Well, mine was reading vacuum and boost aright. I dont know what i did but now the stock gauge wont read vacuum or boost correctly but the autometer does. And it still reads 18 T2 (20 actually cause its always readin2 lbs at vac) and no problems, hope you get the right set up or ask me for a pic.

the vac diargram has been posted too much, do a search.
the afpr line t's into the line coming off the back of the upper manifold, right above distributor
