Fuel Pump 1972 280SE 3.5

[Panhandle]

Hi,

Don't know if anyone can help but, just had the fuel pump replaced on the above car as the old one had sprung a leak, and now the car runs ran like a bag of spanners, and continually konks out.

The spark plugs are sooted up terribly, so I am thinking that maybe she is getting too much fuel.

First of all I was wondering whether there was an adjustment on the pump to regulate the fuel flow, but I couldn't see one.

All help most gratefully appreciated.

Hi

There is a fuel pressure regulator on these vehicles but I doubt thats the problem. Its more likely to be the air pressure sensor situated on the side of the flitch. These cause similar problems to what you are experiencing. It is probably coincindence that it happened at the same time.


Hope this helps
