How do you identify ethonol resistant carb kits?
 

How do you identify ethanol-resistant carb rebuild kits? It's such a well-known issue, is there anyone actually selling kits that aren't? I see an Edlebrock kit from Summit Racing and a no-name kit from Dennis Carpenter that aren't identified as ethanol-resistant. Daytona Parts Company markets their kits as ethanol-resistant of course.

I believe all carb kits made these days are ethanol resistent. I haven't run into any that weren't. Just the old NOS kits that you need to beware of.

I had a failure of a ethanol resistant power valve in the late model Holley on my chevy truck took very old one out of flathead carb it went 10 years ---so being new and labeled ethanol resistant may not be any better than ordinary kit

Rubber line from fuel line to fuel pump cracked in only 2 years for me. I usually buy from C&G, cant say for sure on this item, usually C&G has been good to me. Where to buy a good one ?

Do you recall if that power valve was a genuine Holley or maybe it was one of those generic 6.5" out of a rebuild kit? I had one of the latter fail in maybe a year without much actual use, not anything like a daily driver would see anyway. Its replacement seems to be OK. But .. keep an eye on plugs they sure foul up fast when the power valve goes.

Some of the consensus I've heard is A. Replace any rubber fuel hose regardless every year or so, or B. Use rubber fuel line that is rated for fuel injection service.

It helps I think to buy parts and components and consumable items from actual dedicated carb guys versus rock bottom bargain basement no-name parts or kits from say, Am a Zon. Parts can look identical sometimes, but perform very differently.

Those rubber vacuum caps on the parts rack - I've had the el-cheapos fail in less than 6 months, just fall apart. I don't know what it is they are leaving out of the "recipe" but anything for a buck I guess. Don't get me started on defective ignition condensers. If I ran a parts business, and couldn't stock dependable condensers, I'd just stop carrying them altogether. That ain't gonna break the bank.
