    looks like gas stations will soon be going to E-15. Any thoughts on what effect this could have on our old F-134's?

    Mmm. I understand that the ethanol affects the rubber and plastic parts in the fuel system. I'd think the E-15 would affect any old car equally badly.

    If you have a bunch of junk in your fuel tank it will break it loose and plug up the fuel filter. Old rubber fuel lines may not handle it well, maybe pick up a rebuild kit for the fuel pump and carb.

    It's not kind to old crusty stuff (it's clean it up and break it all loose), but if you reline your fuel tank with something like POR-15's kit, put in all new rubber lines, and fresh kits in the carb and fuel pump you won't have any problem with it.

    I run my 63 VW bug on E85 (been on it for 3+ years now) and love the stuff. Burns real clean.

    I've heard some people complain about it attracting too much water, but I think if you drive it fairly regularly you won't have a problem.

    I run E10 in my 62 CJ right now (with all the fresh fuel components) and it does just fine, runs real nice and no issues with water. It (unfortnatly) sits for a month or two at a time sometimes (and sometimes many months) and never an issue so far.

    The big place I have heard complaints that were viable( in other words something other then replacing 30 year old stuff) in my book has been in boats, namely carbs. Not sure about automotive carbs but some of the boat guys are having some real trouble with it due to heat soaking the carbs boiling off the fuel and leaving a residue then fowling the carbs and the guys having to get them rebuilt for $$$$$$, buddy just had his done for $1200 ouch.

    think the E15 nozzles will be marked as such........regular unleaded should still be available and used......least that's what I've read

    Everything here is E10 (with the exception of E85, but it's not available here in town)

    I've read the same thing. The only way to get E15 is from a specific nozzle/pump. Nothing you're going to accidentally pump into your Jeep.

    E10 sounds like it's most everywhere now. All gas pumps in Utah are E10 year round starting this last summer.

    Missouri is Ezero for regular 87octane unleaded unleaded plus is 97octane E10 same price, there is an E85 pump here in town i ran it for grins, needs to be a touch richer in the carb, double check timing once it is switched over. ethanol absorbs water then the water will settle out when it gets colder the water can freeze ad cloge your fuel filter, aviation suggests a sediment bowl to collect the water and placing the filter in a warmer location to melt trapped ice.

    I put new gas lines from the fuel tank, fuel filter and they are metal "not copper" and what soft lines I used are not rubber. All the fuel lines these days are made of Neoprene which is impervious to degradation by gasoline or other additives.
