MotorvateDIY: How to Check Fuel Pressure
As our cars age, they will start to need more maintenance and we will need to learn more about how to troubleshoot and repair them.
With that said, I would like to introduce: [b\Motorvate's DIY Garage Ep.36: How to Check Fuel Pressure[/b] All you need is a $65 fuel tap and a cheap (mine was $9!) 100 psi pressure gauge. I hope it will be helpful, either now or later  Here is a link to CJ Motorsports Fuel Tap: https://cj-motorsports.com/products/fuel-tap-npt-2-bolt Last edited by MotorvateDIY; 07-27-2020 at 07:47 PM. |

I got one of the first one's that phunk made.
 I used an tee to turn the gauge. Plus I can tap into the tee for remote sensing later.

Just installed one on Friday; quick and simple to install and such an easy way to be able check the fuel pressure considering our cars don't have Schrader ports to be able to connect up a test gauge.

Took about 5 minutes to install Phunk's fuel tap and pressure gauge since my upper plenum was already off
That was the last mod I did ... cause of how easy it was

The problem with using a guage, is that you can only see the pressure at idle.
That $9 gauge was removed after that episode was shot and replaced with a nice Honeywell 100 psi pressure sensor, connected to my data recorder.   On a future episode we will show much the stock fuel system varies in pressure. Last edited by MotorvateDIY; 07-26-2020 at 01:16 PM. |

I've got this mod too.. gauge is looking pretty rough after the last couple of years in that hot engine compartment.
