Amazing that you guys can still find cars like this--------
must be sigh-ca-dell-ic
Anyway on mine, that sat for many years, the fuel tank was a big mess, about two inches of crapola on the bottom and rust on the upper surfaces---no leaks.
When they sit with not much fuel, the bare metal rust and falls in, take it out of car and clean it out, then put in about a quart of ball bearing about 1/4
inch in size, available from bearing store, get Lynne to shake it around for a few minutes each hour for about two days, flush out with hose and rinse with gas, if you really want to get all the little hard to get places, use some muratic acid like they use to clean concrete, do this outside, wear rubber gloves, eye protection and be careful

-----------
rinse out several times with water then gas again.
Take the valve out before you do anything.
Carburator, clean out, put in new accelerator pump rubber part, and that little o ring under the J tube
New fuel pump
Brakes,--- do everything that is rubber, plus flush the entire system out several times, those little vacum bleeders work well for this, but if all is off,
compressed air works but is messy.
Diffinately, do those double lip seals on the tranny
If you want to replace those rubber drive shaft boots, please send certified check for 12k for first two, price drops quickly for the next set-------
which would be mine
Now that you have this car, it will take all your time, so to help you out,
I will take a couple of those old fibergalss boats off your hands---like that Scimitar and the Fishy one with those ugly fins
Congradulations---------
