Gates 31835D Diesel Only Fuel Tank Cap - Ultimate Secure Solution for Diesel Vehicles Review

A very good replacement for the gas cap that I lost because I forgot to put it back on. I like that it's green. It closes well and clicks when tightened.

good fit and long lasting. I bought this to replace the black cap on my diesel work truck. I hope this helps to discourage my employees from putting petrol in a diesel truck.

I love that this cap is green (so I don't foolishly put the wrong gas in my truck again) but I'm bound to lose it as this does not attach to the vehicle.

Arrived quickly, works as advertised. Ideal for the optional RDS tank on a 2011 Super Duty body. Tested to fit Ford factory filler neck and it fits. Not what I bought it for, but I think someone would want to know.

I noticed a rubber o-ring in the stock gas cap on our 2004 Chevy Diesel that looked pretty worn and cracked, so I went looking for a new cap anyway and only came across this green diesel. labeled cap and knew it was the one to get! It fits perfectly as it should and with the markings there is no chance of a tank pump error if another family member borrows the truck and needs to fill it up. Good buy!
