Here's the pump I originally used, and am using again now - it's
really cheap ($12) and worked great for over a year until the orange threaded top cracked. If it breaks again, I'll just get another one. You can cut the feed tube to length and screw it into the drum hole as I did with my first one, but now I just unscrew the drum cap, stick it in and use it, then pull it out and reseal the drum again. The gas stays fresher, I don't have to go nuts getting the feed tube the exact length, and the threaded piece doesn't even get used.

Avoid the pump below (Tuthill SD11) like the plague . I tried for three months to get it to pump reliably and not spray fuel all over me and my bikes, and finally gave up:

There are really expensive rotary pumps that look like quality units, but I would only consider buying one if I knew for a fact it worked well. I wonder what the factory teams use?
