This car is a slant Volare, the PO added a small electric fuel pump and BYPASSED the mechanical pump. Yes it starts immediately, runs great, but I do not like the NON dependability of it should the electric pump fail. The mechanical pump does suck air, I want to run the fuel line back with that pump keep electric pump too I guess.
Can I test the mechanical pump with vacuum gauge? and how mch pressure should it have?
