INSTALLATION:  

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 label install location (see below for reference). After installation, be sure there is 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.  If you choose to 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.

CNC Fab NOTICE:

We know it may be cheaper for those wanting to save some money and have a local hydraulic shop make lines, but in our 20yrs experience, it is not advisable due to the amount of thermal cycling and engine sees.  Normal hydraulic is meant for normal hydraulic use, NOT on the engines. We have sold over 10,000 of these HPOP Hose kits.

DieselOrings Note: We have found to acheive a long lasting repair and seal on the pump, the thread fittings on the pump fittings require application of the LocTite 680 sealant. The seating area on the pump surface is different that what is milled in the cylinder head. The cylinder head fittings do not need the LocTite 680 compound. Allow at least 3 hours for the LocTite to cure before attempting to restart the engine. 

You can add a protective sheath to protect adjacent wires and hoses to the hose kit. The bare stainless steel braid can be very abrasive to items that it may come in contact with during vibration of the engine. Use the checkbox above and we will install the protective sheath on the hoses.
