Description
The Bostech DEC021616 High-Pressure Oil Rail Ball Tubes (Set of 8) connects the fuel injectors to the high pressure oil rails in your Ford Powerstroke. Also included in this kit is an oil rail ball tube installation tool. This tool is needed to install the ball tubes and works as an alignment tool. Leaking O-ring seals in the oil pressure manifold will allow high pressure oil to blow by the base of the ball tube that connects to the injector. Oil traveling into the opening of the connection will blast away at the injector seal until it eventually fails. Eventually the seals can begin to leak which can cause hard start or no start conditions. All Bostech products are designed to maintain or exceed OE specs.
Features:
- Direct Replacement
- Attaches Fuel Injectors To High Pressure Oil Rail
- Installation Tool Is Included With Kit
Manufacturer Warranty*:
13-Month / Unlimited Mileage

So so
Jason | May 18th, 2026
Overall, I’m 50/50. 4 out of the 8 cups had scratch/dent marks on the bottom of them. I ended up just using the O-rings and reusing the Ford cups. The tool I never used; it was not set up for a torque wrench, unless using a crowfoot wrench. I had high hopes for this kit but was disappointed and didn’t have time to inquire about replacement cups. O-rings felt solid, and maybe it was just quality control issues, but purchase replacement O-rings or cups to be sure.

Mostly worked

5 of the 8 in my kit worked great, I had 3 in my kit that the tool wouldn't fit over, so I couldn't tighten the nuts down properly. I ended up reusing 3 of the old ball tubes that were going to be replaced; I just ended up replacing the o-ring on those instead. The ones that went together nicely worked great, but I wasn't stoked about the ones that didn't go together. Truck is back up and running, and my customer is happy about that. I think they make a nice product when it works the way it should.

Seems to work as intended. Took the truck on a 500 mile trip this weekend with no issues. Fixed my long cranking issue.

It worked with some banging
Timmywu (Utah) | November 21st, 2024
The socket tool didn’t fit over the new nipples without some force. I had to use a hammer to get it to slip over and tighten them down. Almost felt counterproductive but the truck is up and running smoothly now.
