Which transfer pumps are being used to drain gas tanks? Was thinking about investing in an electric one. Any recommendations?
Are you going to be doing it often? I bought a fairly cheap one last year from autozone because I only needed it once. If it's something you will be using every time you're at the track I'd spend some money on a quality pump. Check Summit Racing.

Going to use it multiple times a weekend at the track so rather find something reliable. Was just curious what everybody else is using
I have one of these for putting fancy gas into the bike. https://www.ebay.com/itm/Water-Pump...558157?hash=item287b50650d:g:LeIAAOSwcOtcrERl Use it to pull out as much as it will from the tank, then use a simple bulb siphon to get the rest out of the tank.
I built one for about 15 bucks. I used a generic fuel pump, 6 feet of fuel hose, in-line fuel filter, a battery tender type line with connector and a foot of metal brake line all ordered off of amazon. I can run the pump off my z125 battery tender plug or my jump box with a cigarette plug adapter. Whole set up fits in a small ammo box I got at harbor freight on sale for 5 bucks. I can get 99 percent of the fuel out of my gas tank no problem.
Same set up I use, including the HF box with the exception I have access to a lot of fuel pumps based on what I do for a living . I use a pump that is meant for export / desert markets. They are damn near bullet proof and won’t burn up as quick from running dry. I use ones spec’d for v8’s as they flow more but don’t have as much pressure. Just make sure you know where the lowest spot in your tank is, you’ll thank us all later. Also be careful if you have foam in the tank. If you do I’d go the route of draining via the fuel line from the tank, you don’t want to be jamming a hose down through foam as it will clog your fuel filter sooner rather than later. You can easily make something up with a t fitting and a quick connect cap for this.
Fuel injected bike? If so, we used the pump in the tank to get the job done. We had a harness lead for the pump and tubing for spigot that went into a clear VP can.
I don’t think adding basically a hole in your pressurized fuel system is the best/ safest thing... dumping oxygenated fuel onto a hot engine doesn’t work out well....
at the lowest point of the tank? The tsnk isnt pressurized just everything after the pump is. Putting a petcock in allows for passive draining vs a traditional siphon.
This is what I was going to suggest. Ensures the most amount of fuel gets removed and does so rather quickly. I would think it rather easy to wire up a separate switch to provide 12v power to the pump when the ignition isn't on. From there use a high-quality T or Y-valve to route a separate line away from the tank to a spot easier to drain from, preferable away from heat sources.
We used a quick release pin for the tank and had it off and on a small stand in a minute or so. Then used a 12v battery tied to a fuel pump connector so we could power the pump when it was on the stand. Had a spare fuel line connector also plugged on the pump when it was on the stand. Quick release tank pin was key to making it an easy process. Picture of the tank on the stand.
Liking the ideas. But I'd much prefer to get an electric pump that I can stick into the tank rather than having to remove the tank each time. The hand pump ones keep breaking. Few good ideas on building them here
I put one together using a cheap inline fuel pump for a car, basic rocker switch and old MC battery. Takes a few minutes for a 5 gallon transfer but it was $20 or less. Used heat shrink and zip ties to hold pump to battery and switch.
