Can you identify this tank? Efi conversion

Can anyone tell me what tank this is. Looks lime a blazer tank but the drop off in the tank top is wider than any I have seen. Is there a fuels pump/ sending unit that will work with this tank?

Hello Door Doctor. What are you trying to do? For EFI, you can always add an external fuel pump. Also, most EFI tanks of today, have a baffle for the fuel sloshing around. The sending unit can be modified to accept a fuel pump.

An example of modified EFI sending unit, with a stock fuel tank, is in the LSx Swaps section on this site. "Another way to skin the cat". The member is dayj1. It's a very good read. I hope this helps you on your quest.

Don't use an external pump. You will regret it.
Most tanks don't have baffles but instead use an internal assembly like the picture that keeps the pump submerged in fuel even when the tank is almost empty. This keeps the pump cool and cuts down on noise.
