Fixing up an old 7 that hasn't been run in a long time. I'm gonna replace the fuel filter, but i think there's still bad gas that i need to drain but i can't find a drain plug. what should i do?

What an effin' mess man, I had to drain my tank a few months back, it sucked.
What year is your 7 ? I have an '84 and their is a drain plug right on the bottom of the tank.

1979 limited edition. i looked, but didn't see a plug anywhere.

Alex-7

Well then, I think your left with no choice but to drop the tank (I hope it's not too full, if it is than be shure to put a jack under it) Just undo the two metal straps that hold it in place, it's a fairly self explanitory process once you get started.

why couldn't you just siphon most of it out the filler hole?

dont mean to hijack here
but how would one drain the oil on a 1979 SA
when the plug wont budge

Alex-7

Your gonna have to budge that plug, either that or drop the pan.


as for siphoning gas, thats a good idea too. I was thinking along the lines of a major tank cleanup (ie sludge removal) but I guess you could just siphon it out and change your fuel filter every so often for a while.

its gonna be a HUGE mess if i drop the pan

To get the old gas out. Disconnect the hose from the carb or at the metal line and put in a long hose, Put it in a jug and turn on the switch, The electric pump will run it out for you without any trouble.

what do you mean by "turn on the switch?" does that mean turn the key without actually starting the engine?

Alex-7

Yes.

Hades12, I thought the fuel pump in 12A cars wouldn't work unless the engine was running ???

Correct me if I am wrong, but a 1979 would be carburated, and the fuel pump should pump when the key is turned on, so the float bowl fills before you start the car. The 84-85 FUel Injected SEs fuel pump doesn't come on untill you start the car. Do you agree?

Hades12

on the 84 and 5 12a cars the fuel pump only works when the engine is crainking 83 may be the same way. 79 to 82 will run with the switch on. I dont know about the EFI cars.

I use this method to drain the tanks in all my junk cars. did an 85 the same way just knocked it out of gear and spun it till it was empty. Luckely it only had a liter in it.

Hades12

That is what I mean.
