I've been welding up a new steel petrol tank but I'm not sure how to get petrol out of it.

I'm planning on using a single HP pump with no swirl pot or lift pump. The tank has baffling so as long as I'm not running on fumes, I don't think fuel supply would be a major problem.

My first idea was to put two connectors on the side of the tank at the bottom with some pipes inside going to the very bottom. If I were to do that, what would the best fittings be? How about welding some steel tube in?

The other idea was to have supply/return on the top of the tank with pipes on the inside going down to the base. Would a HP pump be ok lifting fuel up like that? I'd be mounting the pump behind the seats near the bottom of the tank.


The tank as it is now:

I think someone forgot to cut the two end pieces properly. It gives me some extra material for the baffles anyway.

A small 2" deep cylinder, say 3 or 4" diameter, welded to the bottom of the tank, with a smaller diameter hole in the tank (2" maybe) to feed it, and a take off from the side of that cylinder is how I'd do it. Well, its how I did do it. makes a self fed swirl pot,
Mines carbs, so add you return in anywhere on the tank and you're sorted
