I use a Hemi type pump on mine but it has a max of 7.5 psi pressure. Carter has several. The #4589 pump has a 3/8" inlet. I use the 3/8" Hemi fuel line from the tank and am planning to switch over to the 6.5 psi #4845 from my current 7.5 psi Hemi type pump. You can get whatever you want from Summit. It's not a bad deal except for the mandatory $9.00 handling charge...or is it more now? Check out the available Carter pumps on the link below. Click on the part number for the specs.
