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.

Absolutely recommend for active dogs or puppies

Absolutely recommend! I have a 10 month old puppy and he has been obsessed with this since the day I bought it a few months ago.

Base of you is very durable
Color: Blue
Overall this is a fun toy. My German Shepherd loves it. The ropes were chewed off within the first hour which was disappointing. Using it for treats did not work because the opening is so large. It has become only a chew toy and it is very durable. Since I bought this to enjoy the extra features, I am disappointed. I was able to buy three chew only toys for the same price. I still give it four stars because my dog likes it so much.

The dog will destroy the ropes and eat them be careful with this
Color: Blue
The rubber part is very durable but the strings or ropes are not. Puppy is eating the strings and having a hard time pooping them out. Just cut them off close to the knots and watch for them to eat the strings they pull off.

Is not as durable as they say for large dogs
Color: Multi-colored
My dog loved the fact he got a new toy and he loved the toy itself. Carrying it around and shaking it, that is. The ropes are small and pop right back out of the ball. They are more for a small dog to tug on. The suction is strong but still not strong enough for a 100 lbs Rotti. He kept grabbing the eleasic ropes and pulling off the floor.

Even the rope is awesome!
Color: Multi-colored
The suction power on this wasn’t the greatest. Even using the sticky patch provided didn't keep it stuck to the floor. I will say though: I was terrified it would destroy the cheap flooring I put it on, but the sticky stuff didn’t harm the floor at all. The toy itself has been fantastic. My pup loves to chew on all parts of it (the ball, the suction piece, and the rope) and it’s held up against his jaws of steel. I will be purchasing another one of these once he’s finally destroyed the original (we’ve had it almost 3 months with just about daily use).
