Cleaning/flushing a fuel tank

[Danglerb]

Last time I just took the fuel tank and radiator to a radiator shop and had them flush both and pressure test, but if its something simple I'd just as soon do it myself. Maybe not. The tank is out and sitting on a shelf.

Take the gauge sending unit out of the tank, and look straight down. You will see the screen for the fuel line inside a cylindrical baffle with no top. All the crud will be there, and you will wonder where all the rust came from inside all that plastic.

I think you will probably give cleaning a shot after you have a look. I did go to Home Depot and get a PVC T fitting to make a wrench for the sender cap. Just cut slots to go over the fins on the outside of the cap. Cinch that sucker down hard, and check the O ring.

I took the sender cap to Home Depot and looked at the pipes, but didn't find a good fit in ABS or PVC. Did you just get kind of close and "make" it fit once the slots are cut?

I think I decided to try and make one out of an oilfilter socket, but haven't done zip.

I use a HP cleaner and always had good results.
As already said the crud is in the dough nut at the bottom.

HP = pressure washer?

Sorry - High Pressure washer - yes

Just making sure it wasn't.


I'm a bit chicken to hit the plastic tank with a pressure washer, but I may give it a try.
