Just kiddinn'!

The slushing compound works great for pinholes. I got it from (shudderr) JCWhitney. Came with phosphoric acid and a buffer and the "goop." Take tank out, remove senders and fittings, seal all holes (but for one) add all your rusty bolts, nuts, washers and small durable parts to the tank with the phosphoric acid (hey, why not kill tow birds with one stone?!), seal the last hole and shake, turn and rattle. Dump out acid and add buffer then repeat shake-down. Dump debris from tank then rinse several times. REmove all plugs and rinse again. replace plugs and add slushing compound. Turn every-which-way then pull plugs and dump extra compound back into can. blow fuel pick-up tube and drain plug out with air and let dry.

I would also suggest replacing cap, filler hose, and any soft fuel lines. Also critically inspect your hard lines as they can get boinked by rocks or jacks and tend to corrode right att he clips for holding them to the chassis.

Mike!
