If you are gonna play with your fuel pressure relief valve, you really should have a way to measure fuel pressure.
I bought 100 ft of nylon tubing and 10 sets of fittings to make the pressure measuring kit (pic below). The banjo bolt is tapped with a 1/8 tube quick disconnect fitting. It replaces the banjo bolt at the IP going to the fuel filter. Comes with 7 ft of nylon tubing, plenty long to run into passenger cabin and a 1/8 female NPT fitting to the gauge (not included). You supply the gauge of your choice. The gauge must be 1/8 male NPT to mate up to the fitting. It should be glycerine filled 30 psi unless you want to go higher.
I have 4 kits at the moment and need more banjo bolts to make more.
Please PM me if you want one.
