Hey guys. I have a sumped stock tank that I've been running for 3yrs now. Gonna be making the switch over to E85 next week and will be running it in the same tank for now. Come spring, I was planning on building an alum fuel cell for the car. But after some reading and talking w/my buddy I see that people are anodizing the alum cells to keep it from corroding. But it seems to be a 50/50 on if it needs to be done or not. Are any of u guys running E85 in an alum cell? If so, is urs anodized? I know I can get a plastic one, but it won't work for what I'm trying to do w/my car...so no plastic cell suggestions please..lol thanks guys. And pics are more than welcome

 

I'm not sure about the anodizing, but u prolly shouldn't use ur current tank for e85. I've heard horror stories about running e85 threw an old tank n all the gunk in the tank being loosened up n run into the motor. Hence y I bought a new tank to run e85.

 

here we go again.... its fine, i ran my stock tank and now a fcs race one with no problems.

 

I am using a stock tank sump with e85 as a matter of fact I haven't drained the tank from race to race, a month at a time, however since I've mig welded the sump and it leaked I sealed the outside with body sealer and undercoating, and lined the inside with tapox tank sealer. http://www.ebay.co.uk/itm/Tapox-etha...-/370733653346 I haven't had any issues since.

 

When I called rci they said no the tank will corode, but they can coat it if requested

 

mr.parks want to chime in?

 

Just drain out any ethonal if you know the car is not going to be driven for a long period of time. "Pickle" the whole fuel system by puting in some 91+ octane in the car and run the car for a couple min. you should be just fine.

 

my car has had the same tank for 4 years, and i have never drained it all i do is change the filters and roll with it

will the e85 myths ever stop lol

 

I understand not everyone has had this problem but I know of three cars personally that have.. Two got clogged injectors n caught it in time, one ran too lean n blew the motor.

 

the only problem I've ever had from using ethanol is dried out rubber lines. my fuel line from pumps to rail is soft aluminum lines known as hard lines, from hard lines to rail I have steel braided lines with rubber lining, I've experienced these rubber lines dry rotting and and cracking "only" when I tried to bend or straiten them after a year of usage, I've been running e85 ever since its been on the market. never had aluminum problem, only problem with rubber. your intake is aluminum, head is aluminum, pistons are aluminum, its a stupid myth that e85 will corrode aluminum. rubber yes, aluminum no! (alcohol displaces moisture ever gotten drunk?). that is why its bad for rubber, it dries it out. Also its hydroscopic mean since it attracts moisture, notice when you run E85 water drips out your exhaust? In a steel tank such as OEM the moisture it displaces does not go anywhere so it " can" not "will" causes rust in the steel tank if not coated. but aluminum it does not make sense.

 

correct rubber is an issue with it this i 100% agree with this also means you need to watch your regulator because of the rubber diaphram within it
