Damn! Feeling a little Ramboesque are we?
Don't get your panties in a bunch, Dude!!!

 

If you get a small tank you'll want one of these...

 

and one of these.

 

Nope, it's an 06

 

I put my petcock on the left side. I made new mounts, tunnel & bottom to be a true flat bottom. I'll take some pics of it tonight.

If you're talking about the vacuum line that runs to your petcock now, you will eliminate that with a custom tank unless it uses a stock-style petcock. All it does is shut your fuel flow off should you leave the petcock on. If you're talking about the vacuum line deal on the right side of the actual tank that's just an extension of the overflow in your current filler neck. Your cap is vented so you don't need that anyway.

I can also do these tanks (or any tank for that matter) on EFI bikes with a stand alone fuel pump/regulator/return set up I put together for a bike I'm working on now for some other guy. He hasn't decided on a tank yet so it's not installed.

 

This is all before final weld

flat bottom



petcock (chopper style) if it was any where near stock location right or left I would leave unused fuel in the take and run out



brass vented gas cap

 

I need one of those asap, Mike.

 

Mike, what do you think your tank holds?

 

Stock tank on a sporty 48 don't hold much looks good
