    time to cut out those tanks and replace em, the ethanol in gas has eaten them up there's no repair, its a replace kinda deal start looking for some alum saddle tanks.

    Dare to be different, if it turns out great you can claim you planned it that way.

    X2..if you don't replace them you will just be fighting the situation for ever. It's only going to get worse over time..

    I highly doubt its the tanks going away.. i would bet its old dead fuel that has built up a film on the inside of the tanks.. just a FYI for the ones that don't know 99% of all fuel tanks used at gas stations are and have been fiberglass for many years. in Commyfornia they have C.A.R.B. (one of the most controled states) that sets the standards for all stations and I highly doubt they would let you put a tank in the ground that eats its self away after yeas of service.. just my .02

    every fiberglass storage tank in my area has leaked and had to be replaced within the past 2yrs not making that shit up(i end up being the 1 to repair em), they'll leak out the fuel, then water creeps back in. wasn't 3wks ago i was at 1 of the stations fillin up my lil blazer with unleaded, went in and paid, started my blazer up, lit a cig, and made it 2blocks before it picked up the water. they took care of it(my bill), but they had to replace both of their unleaded tanks due to ethanol damage. the manager of that store is a friend of my wife's, she said the storage tank company told her they were overloaded with unleaded tanks that needed to be replaced asap due to leakage related to ethanol.

    could be you cali folks get a different unleaded formulation than we do, the shiat is no joke here.

    I just replaced my fiberglass gas tank due to ethanol in the gas that ate up the tank. If you google it you will see that there is alot, alot, of people that own boats have sued the oil companies due to gas leaking in the water from their tanks from the ethanol eating em up.

    Well known problem on boats.

    Every gas station in IL. has had their tanks yanked out, and replaced since using ethanol since the early 90's, most all are soil contaminated too. My buddy bought a low time jet boat, had sat for 20 years. upon using the boat the second time the tank started to fail. Glass tanks have had their day, but in todays world of green that day is gone. Glass tanks are however, still being used in aircraft, oem and retrofit, but there is no chance in hell of getting an "auto fuel S.T.C." in these aircraft.

    We've had/seen and replaced several of these glass tanks over the recent past , seems like more Spectras than anything , have never done a fuel analisys but I've heard and read that the modern fuels attack the fiberglass, the biggest issue Ive seen is flex and crack . (Not that this doesn't take place in metal tanks as well) my feeling is if theres a doubt its not worth a disaster The bottom picture as I understand could possible been from a fuel leak Tom

    Funny you mention Spectras Tom. I actually took my tank apart to fix a loose baffle. While inside I didn't really see any evidence of gas eating into it, but that's just one tank I guess.

    you can buy an additive that neutralizes whatever it is in the fuel that attacks fiberglass. i know alot of 2 stroke outboard folks run it now to keep from damaging rod bearings(2 strokes have roller rod bearings). i seen it on the quicksilver mercury sight awhile back. here in my town, the stores are compete'n and some of them have big signs out frt. " 100% gasoline/no ethanol" so i've been getting my boat fuel there.

    Does anyone know whether a polyeth tank will survive the newer gas formulations?

    should, most race fuel jugs are polyeth aren't they? i know 90% of the lil red outboard fuel tanks are polyeth and they seem to hold up well.
