Is there any performance gains with this method....or is it just to totally drain the tank for milage?

Not sure if it matters pulling through the Draw Straw when the carb sits on top of the motor......it still has to pull up regardless.

Some racers pull from the bottom without a tube/straw. Basically you turn the tank upside down or drill new fitting holes in the bottom. Performance gain.. don't think so but it does help insure that a hose or the clunk does not come loose and put you out of the race.Is there any performance gains with this method....or is it just to totally drain the tank for milage?

Well think about it this. the pickup is always going to be in the bottom, but with the tank upside down there is less room for slosh. Even upside down i prefer a pickup tube as well, as for you can direct it exactly where you want it.to pull fuel from. remember we are turning left.

Gravity is such. it is free flow by fuel volume weight.

On another thought you have more places for a fuel leak to appear.MY.00000002 worth. not much.

They still have the tank pressurized from the carb too.

Tim....are you saying they don't vent their tank? I thought the only return to the tank was from the primer...and it only returns fuel when the button is pressed for priming.

I noticed some of the BIG guys had their tanks this way....I was just wondering if there was some sort of secret gain......Hey we are all looking for that little extra umph right?

Tanner,

I'm sure he meant return from the primer. The pressure from the motor works the carb and does not go to the tank.
We turn ours with the plug/ cap on bottom so there is a little resouir to get ever little bit of fuel out and to minimize the sloshing. The tanks are still vented. Close off the vent and fill line and see how fast it dies! LOL

Make sure if you add the fittings there to find the thick part because there is a thin part and it will be hard to keep from leaking. (took me a couple to make one last a while):thumbsup:

Joey

dont like the idea of pulling trash down lines easier i will stick with my top feed instead and if you drill that resivor and make one the filler the other the vent you can completely fill the tank with a little extra left in the overflow line and fill line:thumbsup:

Now Will,

you know there would be no trash in there if your fuel didn't melt everything it came in contact with, Whats it called, Black death just like the comm drops. LMBO HAHAHA HEHEHE:woohoo:

Have not heard from ya and figured I needed to strike first.

Yes, what Joey said. It should have read primed... I will edit my post.Tanner,
