In order to get my Mav to run (stock '73, 250 auto) I need to disconnect the fuel line at the
filter, point it away from the engine, start the car and watch the rusty gas pump out of the
lines until it turns clear (15 sec). Then I hook the line back up and attempt to start it up. It starts,
runs for a couple seconds then dies. After repeating this for about 10 min it finaly stays
running. If the car sits for a couple of days I need to do it again.
I am assuming that water is entering thru the poorly sealing gas cap when it rains and sits
in the tank, rusting it. Since the water is denser than gas it settles to the bottom of the tank
and in the fuel lines so I need to pump it out before the flamable stuff gets to the carb but
I never get it all.
If I just remove the tank or completely drain it do I need to seal it or can I just fill it with
fresh gas and that will prevent further rusting (I don't notice any rust sediment just color)?
Does this sound like a probably diagnosis. I have tried everything else already.
