fuel regulator

Yeah it has a built in regulator that's preset at 7 psi. I didn't see you mention it was a race car but it sounds like it is if it's going to be that loud. If that's the case the noisy pump wouldn't be a issue. I just checked Summit and see the black pump sells for $165 and the HP125 for $200 so for an extra $35 you get a built in regulator that'll save you money buying a regulator and plumbing supplies and the time plumbing it, but you sacrifice some fuel volume. I guess it comes down to whether or not you need the extra fuel volume.
