Volume is needed on Eddy carbs at no more than 6.5psi pressure MAX. Other carbs can put up with more pressure to keep up with volume. But not an Eddy. You can have less than 6psi, but you better make sure it pushes some volume.

I've had the best luck with using their own (Eddy) mechanical fuel pump (1721 sbc, 1722 bbc). It is a 110 gph unit that puts out exactly 6psi of pressure (no regulator needed).

If you currently use an electric pump only, make sure it meets these requirements. Does it already have a regulator in-line with it? If so, you just may need to upgrade to a larger capacity pump. If no regulator, you will have to find one that puts out 6psi at 110gph or more on its own (or add a regulator).

I also question how close your pump is to your exhaust.
