I have a 2.7 MFI car. Started as a 1972 2.4. Installed a 2.7 kit, cut the heads to raise it to 9.5 CR, 2.7 RS space cam, 4.5 S engine cams and I think it has a MFI fuel pump. Drive it regularly, a blast both bottom and top end. I race a MFI 911 that uses a SC fuel pump. As stated, the fuel return valve on the MFI console handles it. Neither car has the transducer. Maybe it's my fundimental Christian upbringing requiring that I routinely punish myself, but honestly except for a few hiccups they have been incredibly reliable. I have an EFI 965 which I love, but it has produced more issues. Go for it. Bob
