I purchased a '73 2.0 from Dodge City, KS. One yr ago. It's had fuel delivery problems ever since . The car has a tendency to stall at low rpm's. I had the proper vacuum lines installed as well as an anti-flashback valve but not the de-cel valve.
I replaced the fuel filter thinking that was causing the fuel pump to overheat and quit. Now I'm looking for a fuel pump replacement. One aftermarket unit only has two ports vs. three as the orig Bosch. Is it O. K. To splice the two lines going into the engine bay together? Do I need to move the pump as the later models to prevent a vapor lock?
Any help would be greatly appreciated since I'm new to this forum. I've owned Porsches for sometime but only the 14 recently.
