Default Draining an EFI Fuel Tank

I have a small shop and work on bikes from around the area. Something I dislike is removing the fuel from an EFI tank when removal of the tank is necessary. No matter how careful you are some amount of fuel will spill causing a mess. Deciding that there should be a tool for this procedure, I made one. Using an old fuel line I cut off the quick disconnect and added a long hose to it. To drain a tank, I simply disconnect the bikes fuel line, connect my drain tool and drain the fuel into a gas can. Quick, simple, easy, and no mess.

where the heck was this a month ago when i put my apes on , i thought i had 99.9 percent of the gas out, ran it about 15 miles after the fuel light came on but when i took off the line off there was probably 1/4 -1/2 gal of gas pour over my shed floor...........oh well now my shed smells like a shop , but nice to know next time does that drain all the gas out when doing it that way ?? im gonna be putting on some air shocks soon and will have to take off the tank again, u should make a step by step list on how to do it with that set-up

I just pinch both ends of the crossover with needle-nose vise grips near the elbows then cut the hose in the center. Direct each cut end into a funnel or larger hose and release that vise grip. I hardly spill a drop and a new piece of hose is less than a buck.

Jam436,

Your method works just as well, however many of the bikes I receive have a custom braided S/S crossover line installed on them.

You would have to use your fuel pump to push the gas out of the tank,
this is not a gravity drain connection....its the discharge from your fuel pump to your injectors.


A lot of tanks have a second conn. (plugged thrd. conn.) next to your high press. fuel pump conn.
Just pull the plug and add a petcock there for a drain.

I saw that too and passed.
Not only because of the $$ but because I didn't want the hose still connected while trying to lift the tank off.
It's tight enough lifting it off with nothing attached...

To revisit this.

Am I right in assuming that just using this hose the o.p. Came up with will not work?
Because that connection works off of the fuel pump ?
