Recommendation for Fuel Pressure Gauge Kit
 

Can anyone recommend a Fuel Pressure Test Gauge Kit? I have twin Mercruiser 5.0 MPI engines. The Mercury Fuel Pressure Gauge kit is around $500.00. Are there others that are cheaper and are still good? Thanks

I have Gaffrig gauges and they have an electronic sending unit that works for me.

To be clear I am looking for a Fuel Pressure Test Gauge Kit. Mercury part number is 91-881833A2
Description: Use to test the fuel pump pressure, includes: 91-803135 Fuel Pressure Gauge Adaptor Kit 91-806901 Fuel Pressure T-fitting 91-881833A1 160 psi Gauge 7381

There is BETOOLL 0-140PSI Fuel Injector Injection Pump Pressure Tester Gauge Kit on Amazon for $40. Would that work?

Thanks

You can pick one up at any auto parts store or Northern Tool etc.

Yup, $40 cheap Actron trsters at any part store should be fine. Many part stores like Autozone rent testers for free.

Yep, borrow one from the auto parts store for free
