Eric, The fuel pressure gauge that I bought was on the recommendation of DMC Joe. This is the NAPA Balkamp 700-1438 C.I.S. K-Jetronic Fuel Injection Tester (according to the label on the box.) It comes with a variety of fittings and adapters to hook to probably any fuel line in the DeLorean (except for the big ones on the fuel pump). Remember to have a bunch of new copper crush washers on hand when putting your lines back together. Walt (across the bay from you, remember? You are welcome to borrow mine.) Tampa, FL
