I'm running a Holley 4150 4 bbl double pumper carb. . . I was actually asking about the inline fuel pressure gauge in the engine compartment.

But if diagnostics is the only use, that easy enough to check with a diag gauge if something goes wrong. . . I have too many guages in the dash already. . .

Do you think it is still important to have with a carb?
