It's just what my husband needed and he's very pleased with the quality.

This does not fit the EFI Carb at all. Way to long. Because it's metal you can't make it fit either. Disappointing and a waste of money

When I was tightening the fittings to the carburetor the tube twisted slightly and poped the Crome plating off.

Works just like it says it will. Chrome over soft copper tubing. Be careful with it. The small fitting will leak like crazy if you dont take the time to seal it with the right stuff.

Doesn’t fit the 4150 Holley carb it was intended for, don’t want to bend it to fit, as the steel feels very lightweight and cheap

Horrible, does not fit straight and will not seal. Bought this for my Holley carb should be direct fit and perfect since it is also a Holley part. Very disappointing.

Mine didn't leak at all, and fitted great. But on a SBC and normal Holley 4150 without spacer the fuel pressure gauge will be facing the valve cover. I have no idea why they didn't put the gauge outlet on the side. Still, I just bent the tubes up with a small tube bender and works just as well, and I can see the fuel pressure. But I care more about it working than being car-show-ready ;)

This lined leaked. I Teflon tape and it still leaked. I tried returning it and it was past the return date, so no good. It's a paper weight now.

I sure hope my new Holley Double Pumper is better conceived and built that this damned fuel rail! It came to me vacuum packed on a card....ALREADY BENT! That should have been a warning, but of course I went ahead and straightened it, since it was the 90 degree end and not the branch coming out of the fuel block which need the adjustment. Still.....leaked like hell via a pinhole on the long branch on the down stream side of the fuel block. It's going back and I'll build my own system....sure hope that double pumper is better built!Gary Weldele

I put it on following all directions, not tightening too tight, not bending it, the whole shabang. First of all, that thing was the toughest son of a gun to put on the carb, you start one end and try to start the other and it wasnt cooperating, it took a good hour for me to get lined up to start both ends! Second, when i finally got it on and started up the car it was a dang gas geyser!! It was leaking pretty bad and i tried to tighten up the fittings and they were already almost as tight as they could get! so i took that junk off and went with the hose fittings that came with my carb, not as cool looking but at least i dont have to worry about a fire!
