I just inherited my son's Fiero which had the engine rebuilt an then parked for 4 years. It turns over produces oil pressure but the fuel is skunky. What would the easiest/fastest way to dump the fuel from the tank? I have the shop manual for it.
Thanks a Million in advance.

If the fuel pump still works jumper it at the aldl connector and run the fuel pump to pump most of it out. It is probably best to drop the tank and clean it and replace the fuel pump and filter sock though.
Save yourself the trouble and just add fresh gas to the old gas (if there's no need to drop the tank). I've done this with several Fieros which have sat for years, including one with eight year old gas.
I did try that at first by adding about five gallons of new fuel, but the smell of the stale gas is very strong even after I added the high test fuel .. I think I may just add some more fuel and check for fuel pump activity and now I think I'll have a look at the spark situation with a timing light.

If you've already added five gallons of gas, don't add any more unless you're positive the fuel pump is working. Can you hear it hum for two seconds when you turn the ignition key?
And don't worry about the smell of the stale gas. As long as it hasn't turned to goo or contains water, it'll burn just fine when mixed with fresh gas.
Actually no I didn't hear a humm at all ... I cracked the input to the plenum and no fuel so I am suspicious of the fuel pump ... going to check it out in about an hour after I finish my chores around the yard.
Sounds like a toasted fuel pump if there is no hum. You have to drop the tank anyway to replace it so I would just dump the fuel out then. I would check with your local village to find the best place to give your old fuel to as most places have a drop off point.

Hang on...hang on... why such a hurry? It hasn't even been suggested yet to check the relay!
Try by-passing the relay and connect 12v to the proper ALDL connector for the fuel pump. If the pump works, you may not need to drop the tank. If if doesn't work, get ready for some fun.
Thanks for that ... relay (where'd I find that little puppy?) Let me guess under one of the headlights or under the ashtray. Man this little beast is fun ... just joking I have a manual for it ... I've noticed some rat residue and I wonder if the critters have chewed up a wire (or two).

I do not doubt that adding good gasoline to bad will allow the engine to start and run, but do you really want that old crud circulating through the fuel system? I would think that doing it this way might cause a clogged injector.
