[DML] Re: Flushing Fuel System/ Fuel Disposal

["Dave Swingle" <swingle@xxxxxxxxxxx>]

I just went thru this. At each stage I ran the fuel pump directly 
from a spare battery. 

Drain the old gas out of the tank. If there is any gunk in the bottom 
stop, take everything out, and clean it up with Acetone (yuck). Put 
it all back together with good parts and pump. 

Disconnect the fuel filter. Running the pump, run gas out the hose 
that goes into the filter.

Hook the filter back up (replace it!), run gas out where the hose 
hooks to the fuel distributor. 

Tie the inlet and return lines together at the fuel distributor. (I 
used an old fuel pump to make this connection, using the double banjo 
bolt from the outlet side of the fuel distributor). 

Unhood the return line at the tank. Run fuel back thru the return 
line. When you are satisfied that it's clear hook everything back up. 

At this point all the lines have been flushed and you only have the 
FI system to deal with. In the case of the car I'm working on (stored 
for 15+ years without running) the ONLY salveageable parts of the 
entire FI system were 3 of the injectors. EVERYTHING else, including 
tank, pump, boot, CPR, Frequency Valve, the other 3 injectors, and 
Fuel distributor was junk. Frozen solid as if filled with glue.

Moral of the story - if you think that there is any chance that you 
are going to park it for a long period of time, store it dry. In mean 
really dry.

Also - as a point of reference, the car I got all the replacement 
parts from has not run in 2 1/2 years and everything is fine. On the 
15-year car, anything in the fuel system smelled exactly like paint 
thinner instead of gasoline.

Disposing of the old gas - depending on how old (if it still smells 
like gas you're OK) dilute it with fresh gas and use it in your 
lawnmower. The really old stuff is a bigger problem, contact your 
local EPA office.
