Fuel Pressure Tester for 944 Series Porsche

Retail Price: $62.56

This is a fuel pressure tester that we are now making for the 944 series models. It features a correct globe seal fitting that measures 12 X 1.5 MM and fits on Porsche 924S, 944, and 944Turbo (more on this below). The gauge is a 100 PSI (7 bar) and has a 2 inch diameter face.

This is a bit more than a simple fuel pressure gauge. It has an 18 inch (450 CM) main hose that is fuel rated. It also has a pressure release valve/hose that provides for a safe bleed off of pressurized fuel and can be used to test pumping volume of your fuel pump.
Simply attach the pressure hose to the fuel pressure test port (on a cooled engine), ensure the bleed valve is closed and test according to the Porsche workshop manual.

A common problem for many Saturday mechanics is the dreaded no-start troubleshooting. This fuel pressure gauge attaches in less than a minute and can immediately give a go/no-go reading to about half of the typical problem areas (fuel pump, DME, DME relay, fuel pump relay, fuel lines, speed/reference sensors). In some instances it can help with more complicated problems like engine stumbling, engine dying (high fuel pressure) or power loss.

The gauge attaches to the fuel rail test port just like the original Porsche tool. 

An extra note about applicability: this gauge fits Porsche models that have the 12x1.5mm test port. This includes 924S, 944, 944Turbo, 928 (some) and others. The best way to know is to check your test port to be sure this gauge will work for you. A 12x1.5mm test port will have approximately a 12mm diameter (see photo below as an example).

Our Gauge will not fit cars with CIS engines or engines where an angled adapter is needed (such as: 944S2 & 968) for connection.
