How To Check Fuel Pressure -EricTheCarGuy

Here's another one from the 'basics' series. Many times when confronted with a no start or performance problem you need to check fuel pressure. This is a helpful guide on how to go about that process. Many times a fuel pressure gauge can be rented from your local auto parts store or tool rental outlet. If you went to purchase a gauge they vary in price greatly. The biggest concern is the adapters used to tie into the different fuel systems you'll encounter. Outside of that the simple tests shown in this video can help walk you through how to check and interpret fuel pressure readings.

As I learned from ETCG in a previous video, look around your injectors for clean, shiny spots. Gas is a solvent, so a leaky injector would cause them. The only video I've found where the guy just didn't happen to have a Schrader valve. This cat's the best of the best.

Thank you for your videos! Allow me to add that your #11 adapter push button also works to measure fuel Flow according to OEM specs, the way it works is that your fuel pump (while is pumping with the vehicle on) should be able to retain a specific fuel pressure while is being drained, and it should fill a specific amount of fuel In a Marked container within a specific amount of time

Thank you Eric! I have been trying to find the fuel pressure spec for my Hyundai Sonata and you just happened to turn to the page I need and I now know my fuel pressure should be @ 39psi. Thank you very much. Long time subscriber for a reason (on my account as this is my partners).

Thanks for some great pointers, I have an S Type Jaguar that's refusing to start. Went from occasional stall or uneven idle, progressively worse. So, I've now got some ideas to isolate the cause, thanks so much.

Eric, thanks for this video. I have been stumped as to how to measure the fuel pressure on my 2002 VW Passat v6 without a port on the fuel line to do the measurement. But, you pointed out something that I had not considered and that is what to do if a leak is suspected anywhere along the fuel supply line. Thanks, again, for this tutorial.
