Upgrade your worn or heat-damaged vacuum harness assembly with our high-quality replacement. The check valve and filter match the original micron rating and are constructed from Viton material for enhanced durability. Additionally, the check valve features an integral orifice to help prevent cap implosion.

Key Features:

  • Optimized Vacuum Flow: Our harness assembly is designed with the correct vacuum orifice, ensuring optimal vacuum flow without risking distributor damage.
  • High-Quality Construction: While not original equipment from the manufacturer, our harness is crafted to closely match original specifications and appearance. We use high-quality vacuum hoses and fittings for durability and reliable performance.

Please note: Minor variations may occur due to component availability.

Installation Tips:

Attaching the vacuum hose to the distributor cap can be challenging when the ambient temperature is below 85°F. To ease installation, we recommend using a non-silicone-based lubricant, such as WD-40 or CRC.

Great daily sunscreen with lightweight feel
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
I’ve been using this sunscreen daily and I really like it. It feels very light on the skin, absorbs quickly, and does not leave a greasy or heavy feeling. It also works well under makeup and does not cause breakouts. I feel my skin is well protected from the sun and it’s gentle enough for everyday use. I highly recommend it for anyone looking for a reliable sunscreen.

Great for oily acne-prone skin
Size: 3 Fl Oz (Pack of 1)
I have oily, acne-prone skin, and this sunscreen has worked really well for me. It doesn’t feel overly greasy or too dry, and it sits nicely on my skin without making my face feel heavy. I’ve been using it for a long time, and honestly, it’s the only sunscreen I keep going back to because it works so well with my skin. It feels comfortable for daily use and gives good protection without causing extra breakouts for me.

Great for oily skin!
Size: 3 Fl Oz (Pack of 1)
Definitely leaves white cast, I’m pretty fair skinned, makes me look like a ghost. Just rub it in your hands first, breaks into the mineral so minimize the white cast look. It feels lightweight and as someone with pretty oily skin it does a pretty good job!

Great for Oily, Rash-Prone Skin, But Be Wary of the Residue
Size: 1.7 Fl Oz (Pack of 1)
This sunscreen is a really solid option if you have sensitive, rash-prone, and oily skin like mine. I’ve found it’s one of the few sunscreens that doesn't cause any irritation, which is a huge benefit for me. On top of that, it leaves a truly matte finish, so I don't feel greasy or shiny throughout the day. The only reason I can't give it five stars is that it leaves behind small, dried white bits on my face. They can be a bit annoying and make the application look a little messy. Overall, it's a good sunscreen that works well with my skin type, but the white residue is a definite drawback.

This stuff is magic!
Size: 1.7 Fl Oz (Pack of 1)
I farm and garden. I spend hours outdoors in the summer, and for years, I’ve hated wearing sunscreen because it made my face feel hot and sticky. This sunscreen is none of that. I received a small sample tube of it from the dermatologist and instantly fell in love with it. It goes on smooth and covers well. But the thing I love about it is that I don’t feel like I’m wearing sunscreen once it absorbs into my skin. I forget about it! It doesn’t combine with my sweat and run into my eyes, making them sting. It doesn’t irritate sensitive skin or clog my pores. This stuff is magic and I will be using it daily. It’s not the least expensive sunscreen out there, but it’s worth it!
