Hi folks, I think I have this right - can someone verify for me?
I want to upgrade to an electric fuel pump. My mechanical fuel pump is starving the engine for fuel when the engine gets up to normal operating temperatures, and it is leaking oil anyway. I've already routed the fuel lines away from the being over the head, so I don't believe it is a vapour lock scenario. The motor is the stock 1.9 with a weber 32/36 DGAV and Pertronix ignition. On re-routing the fuel lines, I moved the fuel filter up by the carb. I can watch it go dry as the engine gets warm. Neat!!
I'm going to track down a low pressure high volume fuel pump (probably the Carter that has been mentioned before), and a fuel cut-off switch (oil pressure). However, I have 1 question - with the low pressure high volume pumps, is it still necessary to plumb in a fuel return line from the pressurized side of the fuel pump, or does it work like the standard mechanical fuel pump without the return line?
