32 'Tanks' gas tank - fuel surge/starvation?

I'm running a 'Tanks' gas tank on my '32 sedan, which has no front-to-back baffles.
I get a problem when I accelerate hard from standstill sometimes, with a minor fuel starvation at the carb. Ease off and it comes back on line.

Haven't tested my theory, but it seems to be happening when the tank is half full - and I wonder if fuel surge means that air is getting drawn in - especially as the pick up pipe is straight down, at the front edge of the tank (ie facing front)

Has anyone else had similar problems? Any suggestions? Is this baloney and I should re-check my hoses etc? I can;t fit that foam mesh stuff as the gas sender is the usual swinging arm type and would get caught

Any advice appreciated, Limey

BTW I'm running a crate 350 SBC with manual Mr Gasket chrome pump into an Edelbrock 600 cfm carb/Performer intake. I;ve checked floats, pump, lines, filters etc already

Maybe Install a Surge Tank?

When searching Google for Edelbrock Pro-Flo installations, I came across an interesting site. In it, among other aspects, this fellow built a "surge" tank for his 34' Ford Street Rod. He uses a low pressure Holley red pump to prime the "surge" tank, and then a high pressure pump for the EFI system. You could try building tank or buying a small RCI fuel cell and build a similar system. Use the low pressure electric pump to prime the small fuel cell and your mechanical pump for the carb. Then now matter what the situation, you will always have an adequate fuel supply. If you have any questions regarding this install, try emailing the author. I did regarding my Pro-Flo and he responded. Good luck! Ed www.edgesz28.com
