Description
Eliminate the infamous 7.3L Powerstroke #8 injector knock and fuel starvation with this kit from CNC Fabrication. This kit is designed to eliminate the Parker style vibraloc fittings who's rings are prone to failure and are a huge bottleneck for fuel delivery. All the lines are made of mandrel bent 304 stainless steel and are double flared to ensure a proper seal. IMPORTANT NOTES: This kit will allow the factory fuel bowl to stay in its place. If you want to get rid of the fuel bowl later on, you can add CNC's Fuel Bowl Delete Manifold, PN: CNC-7.3-SD-FBDB. By removing the fuel bowl you will need to supply your own 1/2" fuel line from the pump to manifold block. If you are wanting to convert to a 4-line feed AND remove the fuel bowl all at once, we highly recommend this option from CNC-7.3-SD-VMFK. Version Options: Choose your model year for the correct version: Early 1999 or 1999.5 to 2003.

Reviews

CNC Fab HPOP lines

"I had been having trouble with my HPOP lines. I had tried everything and the cheap ones just kept leaking. I purchased the CNC Fab HPOP lines and followed the instruction carefully and no leaks. Highly recommend them."

Dietrich O. (5/5)

Hoop lines

"The age pop lines were wonderful no doubt a little pricey, but I think they’re worth it in the long run. The one that had issues is with the up pipes they’re really hard to install. They don’t reach the manifolds. I think y’all should change brands or fabrications whatever y’all call it This I would say it was a rip off. I do not like them."

Jesus V. (5/5)

15% Quieter

"Works great. Super easy to install. HPX seems to have quieted it at idle by 15%."

Josiah B. (5/5)

More power than ever and

"More power than ever and smoothest it’s ran with its 615,000 miles and still clacking away I couldn’t be happier"

Morgan H. (5/5)

Never got my core charge back

"It’s been 3 months and I’ve called 5 times they always say yeah it’s on its way but still never got my core charge back"

David G. (1/5)

Install was great

"Did it myself. Just like the vidio. They dont leak & look good also. Kit came with ample instructions. I had a serious oil leak but not anymore. . . . thanks guys"

Mark C. (5/5)

Pump works great. I had

"Pump works great. I had other hoses on, they leaked but these have make a better connection cause the have a washer the pushes down on the o-ring better then just your normal flare. So far runs great and no leaks!"

Daniel S. (5/5)

High Quality

"Part looks good and install was pretty simple expect for cleaning sludge and fixing some pre-existing leaks around the HPOP reservoir. Hold pressure just fine with Full Force 180/30s and Jelibuilt tunes."

Tyler Q. (5/5)

Fits great, didn’t blow up when I floored it

"I’m definitely happy with my purchase, seems like nice stuff. I think some loom or a silicone protective finish would go a long way, as well as a cheap line disconnect tool."

Chris H. (5/5)

Worked perfectly and was easy to install.

"Worked perfectly and was easy to install. The lines did seem a little longer then needed on all three."

Q&A

Does this kit fit the Early 99 7.3?
Thanks for asking. Yes this kit will work on an early '99 Powerstroke.
Does these fitting come with o rings don’t see them,
This line kit will include everything needed for installation.
Is there a way around removing the turbo during install or turbo 100% has to come off?
Technically this can be installed with the turbo still in place, but it is significantly easier to do with the turbo removed.
Can I run this hpop with stock injectors?
You can use this stage 2 Hpop with stock injectors, however if you are not planning on upgrading to much larger injectors in the future, I would recommend the stage 1.
Is there a difference between this kit and the SKU #: CNC-422013 kit as far as an early 99 goes?
Early 99 routing is going to be different from the 99 and later style connections. -Mark
