Upgrade your worn or heat-damaged vacuum harness assembly with our high-quality replacement. Our assembly includes the correct micron filter, check valve, fitting, and hose to suit GM ventilated Optispark distributors.  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.

Burns eyes
I am sad to say it burns eyes. The old formula did not. This one does. My eyes are burning so bad. I can’t even keep them open to read a book. I see the trick now. Bottle reads won’t run into eyes, not won’t sting eyes.

Tears free sunscreen
Perfect for my little ones- busy at sports, this one holds sweat and tears! It does require you to apply with patience otherwise they are white ghosts until it fully absorbs but no tears and they do sometimes wiggle so it goes everywhere lol Easy to wash off and does its job protecting their kids skin nicely from the vicious sun - I would recommend!

Easy squeeze bottle
These bottles are easy to squeeze. They aren’t too thin or cheap but still a durable plastic bottle. The lotion is easy to shake to the top for a smooth squeeze. The sunscreen isn’t overly thick. I would call it somewhere between medium to lightweight. It provides good protection as long as it’s applied before sun exposure. It rubs into the skin easily. Recommend.

Works well to prevent sunburn and stays on while working.
Size: 6 Ounce (Pack of 1), Style: Spray
This sunscreen is great! I've worked outside in New Mexico sun for the past few years and this is a life saver. Goes on evenly and doesn't come off while I'm working in the heat.
