FEL-PRO ES 72311 Fuel Injector O-Ring Kit

Great quality and as described

Lots of sizes. Seems to be working on my car AC.

Worked great. Wish there was a note about which colors are used for which end of the injector. This is also a standard kit used for both the 3.7 and 4.7 litre engines. The 3.7 is just a 4.7 less two cylinders like the old 5.2 and 3.9 Chrysler motors or the 5.7 and 4.3 GM motors.

These o rings are good quality and work perfectly on the fuel injecters. Been running the truck 3 months now a have no issues.

I had 3 injectors leaking so I got new orings. When I removed the existing orings they seemed to be a little wider and somewhat flat around the outside which made me a little sceptickle. I replace all the rail and intake orings and solved my problem. No leaks at all. Good price good quality.

Correct part and fel-pro the best

bien

No issues probably have 2k miles on them with my 2011 ram 1500 SLT

Quality is great
