I'm running a sportster tank.. With the sportster petcock work???

[NatiKiD]

I'm still new to these bikes, I have a 1981 GS750L that I got from a buddy for a project. I couldn't find a price worthy stock gas tank for it, so I bought a brand new sportster tank w/ petcock. Will that pet cock work? or will I have to have the stock one some how custom integrated into the sportster tank? I'd appericate the help.

I'd say that's going to be the easiest part of mounting that tank. Hook up the vacuum line if it has one, and block off the vacuum port on carb #2 if it doesn't.

It only has one port for fuel. So I should be good to just run the main fuel line to the sportster petcock, and just block off the vacuum line?

I'm a little surprised the sportster doesn't have a vacuum petcock, but I see no reason why it wouldn't work - fuel fittings same diameter? Solenoid?

Yes...run that to the fuel tee and cap the vacuum port on carb number 3...or stiick a golf tee in the vacuum line.

Thank you!

Yes on dont forget to turn it off ...even for just a short time off the bike. No sense in testing fate and getting even a little fuel into the crank case.
