FUEL PRESSURE TEST KIT - VULCAN PERFORMANCE ('98.5-'02, 5.9L)

This worked well, but it leaked from each fitting on my first use. I was able to tighten those and it quit leaking. It would be nice if it came with a storage cap to install when not in use.

Works great

Fuel pressure test kit worked perfectly,no special fittings needed just plugged right in , highly recommend Geno's garage for all your Cummins needs!

It's a good thing the smell of diesel turns my wife on because I was covered in it after the first use. All the fittings were loose leaked all over. Once tightened up worked perfect. Needs a cap to keep test port clean.

Worked just as expected. No problems at all. Very accurate also, I compared it with the gauge in my truck.

First, I should say that I am relatively inexperienced when it comes to testing fuel pressure. I did have some trouble getting the Vulcan tester valve to thread onto the Schrader tightly. The travel on the tester was limited to only about 1 1/2 turns which allowed the connection to leak. I verified with Geno's support staff (both Robin & John were very responsive) that I was connecting in the correct location. I was finally able to get what appear to be decent seal by using a healthy amount of Teflon tape on the Schrader threads. I'm giving 5 Stars for Geno's staff and three stars for the tester. Even after applying the Teflon tape I wasn't completly sure I had an air tight seal (tested only 4psi fuel pressure). However, the low reading could be accurate since I still have the original lift pump. I'll be going to a shop to verify my pressure reading and look into a lift pump replacement if necessary.
