I am agreeing with everybody else on getting a new one but if that isnt in
the cards then muriatic acid will clean the heck out of one, just be
careful  sttuff is nasty. put the acid in and seal off and shake the tank, let it
sit and  re shake for a couple of days.  pour acid out and use a pressure
washer and  dawn dish detergent to clean it out.. at this point if it isnt
clean enough take  it to a radiator shop and have it boiled out.  later  mark d

Looking  for thoughts, concerns and any BTDT experiences. The last fuel
filter change  (Nov11) had small amounts of rust. My fuel pump is noisy, not
sure if the  filter is collected more bits or if its just old & tired. Before
replacing  it I want to do the lines, tank & filter. So far the engine is
running  great, no power loss since the fuel pump noise began 1800 miles ago.

1. What is the best solution to clean the insides of a gasoline tank?  So
far no major chunks of rust, or leaks.

2. After cleaning, how  effective would a rubberized liner applied inside
work?

The process  purposed is an acid bath, rinse bath to neutralize, then
treated with a blue  liner for about the cost of a new tank.

Do the new tanks have any  problems? And the fuel filter is in-line before
the pump. Should one be  installed behind it too? Will that effect the the
pressures for the injectors?  So many questions! Lots to learn.

Thanks.
