1974 Alfa Romeo spider
Looking for all of the people who were fooling around with the Spica injected cars when they were new. I have read various blogs about replacing the original fuel pump on these cars, some say put a Bosch ....070 pump on and close up the return line others say, "that will make the injection pump overheat" and to put a Bosch ...044 pump on with a regulator and replumb the return line. Back in the '70s someone came up with a way to use a Holley high performance fuel pump that came with a regulator but just the pump was used. No other modifications. There was an article in "AlfaOwner". Does anyone remember this and what fuel pump it was?
