    would it be ok to clean out my gas tank with diesel?

    I just replaced my fuelpump and sending unit and want to flush my tank out.

    I have a TBI would it hurt anything if a little diesel was left in there?

    Personally I'd leave a bit of gas in there, swish it around and use a rag to pick up any of the junk that settles. That's what I did. If you are worried about junk in there, whatevers left should be strained by the pump "sock" filter, and after that, the fuel filter.

    Diesel isn't a better solvent than gas is it? (general question)

    no, but it's less volatile. It's good for cleaning dirty car parts and chains and whatnot. The diesel in the tank will be fine as long as you get most of it out, the rest will dillute when you add gas. Running diesel througha gas engine is much better than gas througha diesel engine..... KABOOM

    I use kerosene, it works great as a solvent.

    Diesel ok,but..

    Laquer Thinner or Acetone will be a much better solvent than gas,diesel or kerosene..also a lot more flammable,explosive,and expensive!..but thats what I use on old lawnmower carbs that are full of hardened shellac,I soak them a few days in Acetone or MEK (a similar solvent)..works when everything else fails..if you cant get it clean with that stuff,nothing else is going to work!.. :crazy:

    Diesel or Kerosene makes a great de-greaser for engine blocks,rear ends,manual trannies,etc..much safer than gas or thinner..not so great on varnish or shellac in fuel system parts though..gas is a better solvent,but a lot more dangerous..I dont use gas or thinner indoors,not since I added wood stoves in my garage! :eek1: :crazy:

    If your tank is galvanized inside be careful the diesel eats up the zinc if it is in there long enough and will gunk things up.
