Locking Diesel Fuel Cap for Peterbilt Semi Trucks

I used this on a 2011 Peterbilt 389. My cap leaked like crazy, and a new gasket didn't fix it. This cap fits a LOT tighter than the old one, and no leaks. The only thing it doesn't have is the overpriced peterbilt symbol. Highly recommend!

No good . They are loose better to spend more money and buy from dealer

It fit my 87 Pete fuel tanks like OEM part.I would buy again, and will if the little bastards try to steal more fuel.

You really can't tell the difference between this and the stock one (except it doesn't have "Pete" on it.. No biggie there) it has worked flawlessly for 6 mos so far in all kinds of weather.The only kind of pia is to remember the key when you get out to fuel but with the cost of fuel and caps ( both of which I've had stolen) it's a good investment . Yes I recommend.

Great buy

All of the internals of these caps are plastic vs. the aluminum of the originals. Time will tell how they hold up...

Received on time, and work just fine

2 months into it and one of my keys won’t lock the cap!!! Very disappointed. Going to try lubricant.
