Excellent product

I needed to upgrade the fuel pump in our 88 silverado to get 58 psi of fuel pressure and this kit made it very simple to accomplish. For accessing the pump we removed the bed instead of dropping the tank. Really glad I was able to find this kit. Thanks gentleman.


Installed pump last week with no issues. Works well!

I received the kit in a timely manner. Appears to be excellent quality. Looking fed to installing in my 93 Blazer Silverado which will do have 6.0 LS power.
