Review on ACDelco GT207 Original Equipment Fuel by Chad Rosier

Revainrating 5 out of 5

This is the correct cap for a 6.5L diesel engine

My old cap created a strong vacuum in the tank. Diesel cars shouldn't have that much vacuum. I found the part number and ordered it hoping it wouldn't cause excessive vacuum and it would work as expected. No more vacuum when refueling. Pretty cheap compared to aftermarket caps.

Pros
  • Product Type: Auto Part
Cons
  • weak
