It is a 59-61 Lark tank that can be converted to be used on other models by using your old neck in the proper location. If you want to use this tank for a fuel injected application you would have to figure out a way to mount an in tank pump inside the tank.

I suppose alternatively a high pressure pump could be mounted outside the tank.

It depends on what you mean by "Converting to FI"

The easiest way is to add a high pressure pump outside the tank attached to a pickup in the tank. That lets you use the original fuel gauge sender, etc. Pretty straight forward by using the original openings.

More difficult if you use an in-tank pump. I added a complete SBC TPI pump/sender unit to the 54 which required a 5" deep sump added to the tank and also the Chevy tank top mount welded to the top of the tank with an attendant hole in the floor of the trunk for access.

For originality use the outside pump, I used the in tank to minimize fuel starvation, which is death to a high pressure pump.

I should have been clearer: I was thinking about a SB Chevy with a low pressure TBI setup as used on 1987-95 trucks.

The TBI uses under 20 PSI so you have more latitude to use hoses and clamps on the system.

The main question is about originality and How much fabrication do want to do?

I'd bet that a pump located outside would be just fine if you don't run the tank too empty. Be sure to put a filter between the tank and the pump.

I used a 91 Caprice 9C1 police tank assembly that was originally a TBI setup but replaced the pump with a TPI high pressure unit. It's a fair bit of fabrication.

I can send a few shots of what I did if you are interested.

I have FI in my '53. The car the engine/trans came from ran 2 pumps, a low pressure in-tank and high pressure booster outside on the frame. Later years of that car used a single in-tank high pressure pump. I have a low pressure external pump (intended for carb'd apps) mounted to the tank along the front below the centerline of the tank. That pump feeds a high pressure one midway under the car. In selecting the low pressure pump I tried to match the flow and pressure specs for the original in-tank pump as much as I could. This system has a return hose from the TBI unit on the engine. I had scored a NOS wagon tank from sasco back when they still had some (fit a C/K pretty well with some filler neck tweaks and moving a hanger) and drilled 2 holes in the upper front of the tank and soldered brass fittings there. Then I have 3/8" brake line tube with compression nuts going through those and down into the tank. The ends sticking out are flared and I just have fuel hose attached. There is also a filter between the suction line and the low pressure pump. So far, this setup has worked pretty well. The only problems I had were the original low pressure pump would intermittantly cut out (it was bad) and starve the high pressure pump. Sometimes it would stall the engine but often was just a stumble. Drove me nuts trying to troubleshoot it since it would work perfect most of the time.
