Can anyone advise?, I am using a earlier Blazer gas tank in my build. What will I have to do so I can use the intank fuel pump with a carbureted V8?.

You need to give more information to get a proper answer to your question.

If the in-tank pump is for a fuel injected engine, it will be too high pressure for your carburetor and you'll need a fuel pressure regulator.

If it was for a carbureted engine, it may work without modification. The best way to go is to remove the in-tank pump and put a hose that feeds off the bottom. Then you can use the mechanical pump on the block and/or an in-line electric pump. That way if you have fuel issues you don't have to drop the tank.

Lets say it came from a fuel injected motor,I don't know. With the S10 frame the machanical engine fuel pump will not fit with out cutting into the front crossmember. Is a fuel regulator between the tank and carb. the answer?

Fuel pressure regulator is easy to install if you are unsure of the pump pressure. On my setup ( Edelbrock Carb ), its set at 6 psi.

Do you know what year the frame is? What motor are you running and I assume your truck is a 49?

We've done 3 of these swaps now, 2 with 455 buicks and one with a 454 (in a 52 chev), and I've never seen issues with clearance between the mechanical fuel pump and the frame, especially the crossmember.

What we always do with the in-tank pump is remove it, and put a piece of rubber fuel line on that reaches to the bottom of the tank. This eliminates issues with the stock pump, especially if you don't know what year or engine it's from and need a replacement in the future. Then you can run an in-line electric pump, or a block mounted mechanical pump. I would much rather have an in-line pump than an in-tank pump, for accessibility reasons.

Yes, Yes, Yes! When that in tank pump quits, and that's when not if, you will wish you had an inline or mechanical pump.
