Bob_the_builder Posted July 18, 2007 Report Share Posted July 18, 2007 As a school project I am working on designing a fuel tank to hold E-85 but I am having trouble finding a material that will actually hold the fuel. I have been talking to others and it seems that the E-85 will eat throuhg many different materials such as aluminum, steel, and plastic. Does any know what material is used in the fuel tank of GM's flexfuel tahoes and pickup trucks? Thanks, Bob Quote Link to comment Share on other sites More sharing options...
oscareltemblo Posted July 18, 2007 Report Share Posted July 18, 2007 I don't think it eats thru aluminum because the heads are aluminum? but I don't know. Quote Link to comment Share on other sites More sharing options...

stoutss Posted July 19, 2007 Report Share Posted July 19, 2007 I know 304 and 316 SST have excellent corrosion resistant properties and you can get it in sheets. I however don’t know without research how E85 affects this material Quote Link to comment Share on other sites More sharing options...
mungman Posted July 19, 2007 Report Share Posted July 19, 2007 did you have a look at http://en.wikipedia.org/wiki/E85 ? Quote Link to comment Share on other sites More sharing options...
KissMySilvSS Posted July 20, 2007 Report Share Posted July 20, 2007 pretty sure the tanks are plastic on the flex tahoes and silverados. I will check though today when I go to work. Quote Link to comment Share on other sites More sharing options...
