Hey all was wondering if anyone knows what an idle vacuum reading should be on a 97 mark viii Lsc with no mods. Just got my Bluetooth obd2 scanner and noticed the vacuum at idle is 26 to 27 psi and I also saw the Evap system hasn't completed it's obd2 tests. Thinking there's a leak in Evap...

gotcha thanks again for the info driller:) cheers all

Yes sir. Sure did. Pulse damper eh. Never heard of it lol what does it do? That explains why it didn't jump 10 psi when unhooked lol Thanks again el presidente:)

if that's not a regulator does anyone know what it is?

for reference here's what i thought was the fpr taking vacuum away from this guy jumps the pressure to 40 so it looks to be good but the little guy on the other side of the rail doesnt seem to change when i take vacuum away or try to pull vacuum on it.

oops the pic didnt post lets try again that's the guy. i tried to pull vacuum on it and the flow only changed by 1 psi. seems to be stuck.. unless it's supposed to do that lol thanks for the wisdom fellas

Thanks for the replies That's the culprit. I assumed it was another fpr And its part of the rail. When I pull the line the fuel pressure changes by 1 psi instead of almost ten on the main fpr when vacuum is pulled. Seems to have a stuck diaphragm lol

hello all, i was testing the regulators on my 97 lsc with the fuel pressure gauge hooked up and noticed the smaller one is not regulating like it should. so i went to the parts store to find a replacement. however they cant seem to find the little one. from what i can see it looks like you...
