NAPA Gas Caps "Junk"
Had to let you all know that I am on my second NAPA has cap in less then a year. First one lasted about a year, took it back and showed the owner the rubber sealing ring was all cracked and falling apart. He gave me another one last month, it's already doing the same thing. I run non-ethanol fuel in my GMC because it sit's un driven during the winter. Any one know of a quality cap ? I was told STANT makes the NAPA cap.

Re: NAPA Gas Caps "Junk"
Interesting -- I've had a locking cap from NAPA for several years and the seal is still good. The one it replaced was the same, and its seal rotted after at least 15 years.... probably closer to 20 years. Although IIRC, I had to buy two at that time to get a good one.

Re: NAPA Gas Caps "Junk"
I went to another NAPA just to see if they stocked a different brand, they mentioned others complains too ? Manufactured overseas, not USA.

Re: NAPA Gas Caps "Junk"
I'm on my second one too. I had each about a year and a half. Both are Murray Ultras. Not even good for hockey pucks! I will be going back to the 20 year old locking cap that still works. The rubber these days... not good!

Re: NAPA Gas Caps "Junk"
It's nothing to do with the rubber. It is the fact our fuel has ethanol which contains alcohol which dries out rubber.
You can get rubber conditioner to help this but it will just happen later than sooner. |

I had to take three Stant caps back years ago just to get one that was actually vented. All three were marked vented on the cap and came in the correct part number box.

Re: NAPA Gas Caps "Junk"
I bought 2 from brothers and 2 from LMC and 2 from Napa. Both LMC caps and both Napa caps leaked like a sieve from brand new. 1 bothers leaks too. Rubber is fine on all of them but the vent valve is open all the time and lets them spew gas. I returned the Napa ones, the others weren't worth the shipping cost.
The other one from bothers was good for a year and stopped sealing. After looking at it, the metal spring washer behind the rubber gasket weakened. The rubber is still good and the vent valve still works. I stuffed a fat o-ring behind it and it has worked for another year. So far so good.
