Re: 1985 Silverado with TPI Fuel Pressure Issues - Long post
Was it a regular rubber vacuum line or a pretty dress up vacuum line?

Re: 1985 Silverado with TPI Fuel Pressure Issues - Long post
It was a regular one. It could've been crimped when I replaced the fuel pressure regulator. I didn't completely remove the plenum when i did it, just lifted it enough to the side so I could get to the regulator. I don't know. I removed all decorated ones a while ago to help with troubleshooting.

Make sure the tank changeover valve is not clogged with debris....I have personally seen a totally clogged port in a valve so bad that I could not clear it out.....
If you have to, totally isolate the left tank...and get the truck working correctly on the right tank...dont try and do too many changes at one time.... ![]() ![]() ![]() ![]() ![]()
