There are only 2 for these rigs, one is longer than the other. I'm betting the reason he wants to know is because one is about half the price of the other

I'm pretty sure they both have the same fittings, just one is longer.
I can't get the info right now, but you may find the answer on
www.zuwharrie.com - there's info there(on the BBS) on fuel pumps, and a 199x Honda Accord fuel pump is the exact same and much much cheaper. If you were to search "honda accord" in their IFS section, I bet it would be on the top of the list!
