Tid Bit. Draining your gas tanks for storage, or service

[Bob Dunahugh]

Drain plugs get hard to pull out if you don't know some tricks. And sloppy. I have a drain port in the gas line that goes from the tanks, to the engine. Makes no difference what, or where your pumps are. I put a tee in the rubber hose, Then a very small gas valve. If you have your pumps at the rear like I do. I have a manual switch ( SPDT). That's close to the port. ( Also, Handy to test your pump flow/pressure ). To drain the tanks. I just put a hose on the gas valve. Open the valve. Then turn the pumps on. One at a time to fill your gas cans.
If you don't have electric fuel pumps. Get an electric gas pump, SPST switch, hose, 2 conductor wire, and 2 alligator clips to connect the wires to your 12V battery. ( Check polarity).
I Also have these same setups on the 4 COPO Yenkos. And on all our cars that are in our (too many ) restored convertible collection. I keep everything. Including the GMC. In clement controlled buildings. Year around at 70 degrees. So spilling gas IS NOT an option. This setup is a must have for the cars that are in that collection.

Some people have attempted to use a hex wrench to take out the plugs and stripped them.
When this happened to me I used a very small pipe wrench on the two or three threads of the plug that were exposed and I was able to turn out the plug.

Thanks for the tip. I have full tanks of gas that’s going bad and didn’t want to try and dump the tanks via drain plugs because of the mess. I was
thinking of pulling a line from the TBI and running a line from it to gas cans and using the electric (in tank) pumps to drain. Where about is your
gas valve located?

Thanks

An aside - Bob, if it matters (it would to us) Knocking that 70 down to 60 or even 55 when you aren't in there - or if you are - will save a bunch of
money in heating costs without hurting the equipment.

Just a side note. When pumping gas with an electric pump connected with alligator clips be careful of making sparks. They don't mix with gasoline.
