I'm chasing a "rich over all loads" condition, and I'm down to the MPS and Fuel Pressure. Car is a 1971 with D-Jet.
My questions are: 1. Where do I tap in with my gauge? Do I check both rails? 2. What is the proper pressure (30 PSI)? 3. What direction is the regulator adjuster turned to +/- the pressure? 4. Any clearly defined procedure? I did do a search and found a couple of related posts, but no direct answers. Thanks! |

I'm chasing a "rich over all loads" condition, and I'm down to the MPS and Fuel Pressure. Car is a 1971 with D-Jet. My questions are: 1. Where do I tap in with my gauge? Do I check both rails? Assuming all is stock, tapping in off the rail that goes to the cold start valve. 2. What is the proper pressure (30 PSI)? 28 psi is kind of what I've always heard 3. What direction is the regulator adjuster turned to +/- the pressure? I believe clockwise..even though that seems backwards 4. Any clearly defined procedure? I did do a search and found a couple of related posts, but no direct answers. Thanks! Are you sure it's not your TS2 (head sensor) going bad? A fautly sesnor could richen all conditions...however it's probably your MPS not holding a vacumm. Try sucking on the tube to the MPS and see if it holds a suction...don't suck to hard you could pop a diaphram. The best way to test is with a vacumm pump at 15lbs. |

[/quote] I'm testing the MPS tomorrow with a vacuum pump/gauge. The CHT sensor looks good (checked per specs with meter). Just for the record, I've covered the basics: New points, condensor, cap, rotor, plugs, wires, coil, battery cables & terminals, ground straps, battery, vacuum lines, fuel filter, TS1, and more... all Bosch parts. Also checked and adjusted valves, timing, points, etc. I prey to god that I'm in the final stretch - I'm getting so sick of wrenching on this car versus driving it, I'm just about ready to put it on the sale block. It's a nice car, and the engine is soild, but this rich condition/poor & inconsistant idle crap is testing my will. Damn you D-Jet, damn you! ![]() |
