Replace your driver and passenger side 94.5-97 OBS 7.3L Powerstroke high-mileage OEM High Pressure Oil Pump lines with a CNC Fabrication™ upgrade!
*Crossover line in the engine picture is not included*
Disconnect the battery grounds before installation to avoid accidentally arc'ing the line on the glow plug relay or the alternator charging lug. Use pictures from the product webpage for routing example. The fittings are marked with numbers to match installation location (see below for reference). After installation, be sure there are no other lines/wires that are touching the lines that could potentially rub through and damage either the HPOP line or the other line that may be touching it. Use a small section of wire loom protector or a larger piece or rubber hose to wrap around the contact point. Many will remove or bend the engine eyelet on the driver side as a precaution, but it is not necessary. Sealant is not necessary, but IF you choose to use any, use Loctite 680 or Permatex 64000 retaining compound (green) only on the fittings installed in the HPOP. If you are unsure of installing yourself, seek out a competent and qualified technician to install the lines.

Just finished installing the HPOP braided lines, they really do fit nice. Even in 36 deg weather they still had plenty of flex in them to get them in with ease. I do wish I would have replaced them when I resealed my HPOP. The truck already had the driven diesel oil crossover hard line. If you have the same crossover on a OBS, you will need to swap the short line to the passenger side and the long line to the driver side.
