fuel cap

I replaced all the fuel caps last March on all 3 of my vehicles. I was filling up Elyza at the weekend and I noticed the rubber seal had already perished on both the caps!

I only use ethanol free in these old trucks (my milage is so low the cost is not a factor).

Any suggestions on a decent fuel cap or replacement rubber seal? Or is just how it is going to be?

Re: fuel cap

What brand?

I've not had issues with my Motorad cap... and I do run regular 87 octane E10 (what I can get, I drive it enough that water absorption hasn't been an issue).

I had Stant non locking caps. I ordered some motorad ones this time around, thanks.

Re: fuel cap

Funny, they make good stuff usually.

Were they old stock?

More specifically, from whence did they come? My nephew will not install a part that was supplied by Rock Auto as he's had many of them fail. Maybe they were returns? Maybe they were manufacturing rejects? I don't know, but he will NOT install a part from RA.

Re: fuel cap

My Motorad cap actually *did* come from RA.

Only issues I've run into was getting sent the wrong brake caliper once, and getting a set of wholesaler closeout KYB struts for a '94 tempo that were very old and had very little gas charge left (excel-G's, they are supposed to be charged!). Otherwise, I've had pretty good luck with RA... just knowing to be careful with any closeouts on things that might have an expiration date.

I got the stants through Amazon..

Re: fuel cap

All the stants look like this after 11 months..

The rubber on the motorad ones are much thicker. I need to order more of them.

Checked my Motorad the other day, over two years and no cracks.
