Upgrade Your 7.3L Powerstroke’s Oil System with Confidence

If you’ve spent any time around a 7.3L Powerstroke, you know the high-pressure oil system is the heart of the injection setup. Over time, the stock quick-connect oil lines can become a headache—leaking, failing, or just not keeping up. The DieselSite HPOL73 High Pressure Oil Lines are a reliable, long-term upgrade for your 1994 to 2003 Powerstroke. These lines are built with stainless braided hoses that feature an anti-abrasion coating to protect against chafing and wear, even in the harshest engine bay conditions. They’re not just tougher than the original—they’re smarter too, designed with threaded stainless steel ends that eliminate the weak points of factory-style connections.

Designed to Fit Right and Last Long

This kit includes everything you need: two pressure lines, pump and rail fittings, and spare O-rings if you choose to use alternate ports on the rails. One line is built with dual 90-degree ends for the passenger side, while the other combines a 90 and a straight fitting for the driver’s side. They’re engineered to follow factory routing or offer flexibility if your setup demands it. Installation is straightforward with the help of included guidance, and once in place, you’ll have a leak-free, rock-solid connection that holds up under pressure. Whether you’re building a workhorse or simply tired of oil seepage, this is the kind of upgrade that brings peace of mind every time you fire up the truck.

Fits: 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 Ford 7.3L Powerstroke

Install Tips:

• The line with two 90° should be installed to the passenger rail using the rear most pump outlet.
• The line with a 90° and straight should be installed to drivers side rail using the front most pump outlet.
