5/16 fuel line double shut off disconnects

[97tiger885]

I need to put some quick disconnects on the fuel lines on the 85 K100. Fuel line is 5/16 inch and the lines are pressurized for fuel injection. Any tips regarding material such as choosing among plastic, brass and steel?  What about type of seals used?

It looks like I need to order 4 5/16 fuel hose barbs with male threading and 2 pairs of male/female disconnects with female threads to match those on the hose barbs.  AND I NEED DOUBLE SHUT OFF, not straight through disconnects.

Space is limited on these lines.  The intake line is about 8 inches long.  The return line takes a 90 degree bend immediately under the tank.

How do I know the disconnects will work with gasoline and ethanol?

Advice appreciated.

When I got mine (2004 Girly) I couldn't find any 5/16" so I used 1/4" together with 1/4" (6mm) bore pipe. You need chrome plated brass and Viton O rings.

why do you need disconnects?  you can easily remove the tank /lines without spillage.  they're not pressurized when it's not running, and i don't recommend removing the tank when it is.
