The 84 6.2 Diesel Suburban I bought has been sitting for over a year. What should my concerns be (if any) regarding the fuel sitting in that tank. We need to do some tests to determine if the injector is bad or not but I was wondering about stirring up that old fuel.

Thanks

Does diesel "go bad"?

 

[beastsuburban]

not that it would be BAD, just due to it sitting over a winter in PA heard that the stuff can gel if additive wasn't put in, we have no idea if it was or not. Not sure how much gas is in the tank could suck up water from the bottom of the tank...

What Now

I would suggest replacing the diesel, Poss lots of water in the tank and if you are going to run the truck anyway you should have good fuel in it plus at least if there is any other problems then you Know it's not the fuel Start with the easy things first.

Agreed. I wouldn't risk it. The last thing you need to deal with is the possibility that there could be water in the fuel. You don't wanna have to clear it out of the fuel lines if there is.
