#8-002ex Extended HPOP O-ring kit with pump hose fitting repair kits

Product Review (submitted on July 9, 2016):
This kit is absolutely amazing! I ordered all except the cylinder head repair kit. My HPOP was leaking from the mounting gasket so I decided to order everything else due to the convenience of having it out of the truck. I highly recommended this kit, the mounting gasket when installing I would recommend a gasket adhesive to keep it on the pump when installing back into the truck. I did not remove the fuel bowl when I did this. There are videos on youtube with good removal instructions. My only issue I have is with this website is torque specs. The bags are labeled with location for the o rings but they should also be labeled with torque specification for that particular o ring. The websites instructions only have a couple torque specs but not every particular part that you can remove which is the only down side. I recommend this kit. My leak has been fixed since and so far it has been a week with no issue. Dont forget to fill the HPOP reservoir back up with oil before starting.
