Fuel pressure gauge

Post by skykng »

My '82 Spider has been acting up lately - as if it is flooded when trying to start it after it is warmed up. It has never required any gas pedal to start it, cold or hot. It won't start. Leave it overnight and it starts right up in the morning. My first thought was ignition but I have good spark. Next was fuel and pressure loss. I want to add an in-line fuel pressure gauge in the engine compartment so by raising the hood I can see that the pressure is there or not if I am having a problem. Surfing the net, I don't find a small one available. Does anyone know a source for a reasonably priced one? thanks........steve

You need to get one that is dampened so that engine vibration doesn't kill it.
This is usually done with oil inside the indicator.

It is generally frowned upon due to the fuel system pressure (L-Jet is about 38 PSI). You don't want to add a point of failure. Get a test kit and test it. If it isn't in range replace the pump or pressure regulator. They won't fail again possibly ever, or for at least 20 years.
