Stainless Steel HPX for Ford 7.3L 99-03

The Stainless Steel High Pressure Crossover is meant to allow excess oil pressure to flow between both heads allowing for better supply to the injectors. By allowing the oil the flow to the opposite head, the issue of pressure spikes are less.

    Leaks

    Posted by Eric on Jul 21st 2021

    Quality felt decent, but the flare was leaking between fitting and crossover tube, so I took it off. Didn’t make any difference on my truck anyway.

    truck seems to run quieter. will probably replace hpop with adrenaline one day, which at that point i won't need this item any longer. But for now it works great. Easily installed in about 15-20 minutes.

    Ive had it on my 00 7.3l for 3 days now and its a great product well built great fit, pretty simple install. I noticed the “7.3 clatter “ isnt as bad, runs smoother . Even talked my dad into getting one for his 01

    Crossover Tube

    Posted by Pete on Jun 30th 2021

    First thing I noticed was my 7.3 Econoline idled smoother was much quieter and has slightly better acceleration. Also notice my fuel economy went up about 2 mi per gallon from 17 -19 mpg. The cost of the tube will pay for itself in saved fuel. And installation took about 40 minutes which was very easy.

    Quality and functionality

    Posted by Shawn on Jun 2nd 2021

    First impressed by the fit up. Tubing bends, length where spot on and quality of material was excellent Trucks idle is noticeably quieter and smoother. Throttle response seems to be improved as well. Once again happy with RiffRaff products.
