Mckenzie Posted November 11, 2015 Report Share Posted November 11, 2015 I have a 2007 Ford Edge SE and some bad minded person put acid in my gas tank. I don't know what kind of acid. I have replaced fuel pump and fuel injectors. I have also cleaned out the tank. It runs well but the only problem I have is the tank coating was burn't off by the acid. Can I repair the tank by using a sealer or is it my best bet to replace the tank? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted November 11, 2015 Report Share Posted November 11, 2015 That is just nasty, every owner's nightmare! Probably be best off replacing the tank. Hopefully the fuel lines are not also compromised. Quote Link to comment Share on other sites More sharing options...
akirby Posted November 11, 2015 Report Share Posted November 11, 2015 Those tanks are prone to rust anyway and a new version is now available so yeah - replace it. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted November 11, 2015 Report Share Posted November 11, 2015 (edited) Possibly mothballs. With the newer type of mothballs, made from parsdichlorobenzene, the clorine in it will create hydrochlorice acid when combusted. Don't know if it can convert chemical with the alcohol in gasolibe to acid, but might be possible. (The old type of mothballs was safe in gas engines, and was sometimes used to boost octane.) As fast as the tank is concerned, it's only a matter of time, I agree, change the tank. Impossible to tell how badly it etched the steel, especially the connections with welded joints. Best buy a locking gas cap. Punks may wait for you to repair the car only to do it to you again as their firm of fun.

Brucifer Posted November 12, 2015 Report Share Posted November 12, 2015 What about the fuel lines? How much damage could be done to them? As long as you are rolling around under the body.... Rock Auto has tanks for about $850. Dunno about quality. +1 on the locking gas cap. As an aside......do these things have fuel filters?

Brucifer Posted November 12, 2015 Report Share Posted November 12, 2015 I saw the in-tank fuel filter earlier in a parts search. I guess I was in denial because I wanted an inline filter. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted November 12, 2015 Report Share Posted November 12, 2015 I suppose you could ADD an inline filter like they sometimes do for the power steering fluid ... Quote Link to comment Share on other sites More sharing options...
Brucifer Posted November 12, 2015 Report Share Posted November 12, 2015 I suppose you could ADD an inline filter like they sometimes do for the power steering fluid ... Now you are making work for me.... Spending too much time and money on LED bulbs. Need to get a new HVAC blower, liftback struts, mudflaps before I worry more about some stupid bulbs. Then again, that's peanuts compared to what Mckenzie has to worry about. 1 Quote Link to comment Share on other sites More sharing options...
