It used to have a Holley blue but it was leaking so I thought it'd be a good time to upgrade to the Holley Black. It was leaking like a sieve when I first got it so I didn't get a chance to see if the blue was performing properly. It does have fuel gauges for each system but they're currently mounted on the motor so all I can see id idle pressure--which iirc is about 5.5. Remounting them on the hood vents is on my "list of things that I should do but never seem to do."
