it shouldnt hurt anything, the sump just lets you get the fuel out of the bottom of the tank, right? try it and if it doesnt work, put it somewhere else.

I had my cell with the sump to the pass. side, when I would get leaned way over to the drivers side, it'd lose fuel in I was below 3/4 of a tank. Personally, I wouldn't do it again like that.

Do the bottom-sump setups give you a way to have any sort of weighted pickup, so it'll move to the side you're leaned to? Or is it a true "sump"?
I'm guessing (no real experience here with it) that with the sump at the rear, you still might starve the engine at side angles if you're moderately low on gas?

No weighed pick up in mine. It would starve if it wasn't damn near full. But I usually spend more time on 2 tires than 4.

A weighted pickup from a top-draw tank sounds like the best solution to me?

Those sumps are designed with a drag racer in mind to allow them to pull fuel from the rear/bottom of the tank under acceleration.
Ive penciled out many tank designs and unless you do baffels or dual pickups etc.. IMHO the best tank design is a tall wide skinny tank, similer to what the TJ guys run behind the rear seat.. Seems to be the best compromise etc..
That said ive started on a tank project that will have a lower baffled sump compartment to allow for the off camber stuff..
Rich i also played with the weighted pickup stuff, i had a large brass weight and with a good hose the weight wasn't enough to pull the hose where it needed. And a light hose would not hold up. The other thing to consider is to verify the hose is rated to submersion in gas.. If its not rated the hose will start to delaminate and separate in layers.. Normally they use a flimsy sold dip hose..
Also just having the center pickup on a hose it may not reach where you want it to.. And any extra length easily prevents it from swinging the other way..
I did a pile of research on airplane inverted tanks and various DIY designs and many had a very narrow swing to allow for that 0 or 180 operation with not much in between...
Anyway here the plan of the tank im working on..

Did some research today, and this seems to be the solution...

This is the same as the now defunct Holley kit, which I just ordered one of for a good price that was sitting on a dusty shelf..
Everyone that has one says it cured their issues 100%.
If I do wind up switching back to gas, they'll be installed in something along the lines of the 2171A..

on my dads cruiser we mounted the sump to the passange side because of a size and location problem (didnt have a better option). Sometimes on good side hills, he gets air in the system and loose power. We then just push it over or winch it back over to get fuel back to the system. Kinda a pain. When it used to be "steet legal," you could actually stall the motor on sharp turns as the fuel sloshed....if you were low on fuel to start with.
On my truck...it is mounted in the back. I personal havent had a problem yet. And i wheel fairly hard...
Suggest, always start the trip with a full tank.

Thats what I'm talking about. Those are some good responses guys. So I'm gonna go with it to the rear because there is no weighted hose. I've had to spend a small fortune in AN fittings though. However, I am putting the cell on the passenger side to offset my weight when riding alone.
