Anybody know what the psi reading should be on the fuel pump for a 1976 124 spider? It has a regulator between the gas tank and the fuel pump. I don't get a reading /nothing but the car will start but not run. If I keep hitting the accelerator it will stay running barely.
I am going to get the carb rebuilt so I will know if part of the problem is the accelerator pump in the carb. Yesterday I was going to check the regulator and by passed it straight from the tank to fuel pump then to carb. Car would not even start. It is backfiring through the carburetor some but I think that is bcause the timing is advanced so far it fires before the intake closes all the way. First things first, PSI on the fuel pump. I am guessing 3-4 # but that is just a guess. If the regulator is working properly that should take care of it . Looked in my manual but could not find any thing concerning the PSI .
Any help would be appreciated.
