Which is better to provide a constant flow of fuel; a sump pick up on your gas tank or an external swirl pot (surge tank)? Is there any point to having both? Do you even use in-tank pumps in conjunction with sump pick ups?

It depends on application and your budget...



If you can afford it, run a big fuel pump off a properly sumped pick-up from the gas tank.

KISS rule.



Swirl pots are an ingenius method to get big fuel delivery with minimal modification of the stock fuel system.

So budget aside, a sump pick up is the way to go. With a sump pick up is there any need for in-tank pumps? And swirl pots are just over kill at this point, right?

No need for in-tank...

Most of the sump pick-up "systems" I've seen are for drag racing.

The sump pick-up "shelf" is welded to the rear portion of the gas tank, since heavy acceleration tends to slosh the fuel toward that area.

Pick-ups are facing rear-wards, and hoses feed the fuel toward the front (first to the fuel pump of course ).

That is correct.

Thank you, That's what I thought, but I figured I had better ask. Ryan.
