I would think with the pump pushing its 3/8 shouldnt bother it much... Could always enlarge it in the press and tap for 1/2 fittings. But I really don't think 3/8 will be an issue

IIRC I used 3/8 to 1/2 push loc on mine. But no it isn't an issue I've experienced yet.

The system just needs a positive push in the supply line. The cp3 doesn't care if its 1psi or 10psi.

I will say, on my lb7 when I changed it to an lbz cp3....(obviously the tune was adjusted) but every time I would slow down it would lope real hard. I logged rail and it was going to like 15,000psi off throttle. I turned my airdog down to 4-5psi and it fixed it.

I looked at fed ex tracking and the weight on my package is 0.2 lbs...... Looks like I will be filing a claim with amazon when I get my package.

I will let the seller respond first. His add clearly stated part number 12-125 holley black fuel pump for 40.04.
I think he realized the mistake and is trying to cover his ass by sending out a similar part number and saying thats what it was supposed to be.

I would say that's pretty much a guarantee. There's a good reason I didn't buy all of these when I saw it first mentioned, but I was hoping the best for the rest of you.

Call amazon. Don't deal with the seller. I just called amazon and asked them for direction on the situation. It clearly states we are purchasing a billet fuel pump. Not fittings.

I'm not worried. Between amazon and Visa I'm covered. Shipping weigh on ad says 4 pound . The description is the same one then on Holley's site
