HPSI Silicone Vacuum Hose Kit - Pontiac Grand Prix GTP 1998-2003
Pontiac Grand Prix GTP 1998-2003
This is a very good kit that will help restore lost power,
fuel economy and emission characteristics to your Pontiac.
This vacuum hose kit was designed and made exclusively for the Pontiac Grand Prix GTP 1998-2003. Made from our high quality silicone lines with thick durable walls, heat resistant molding and strong bends.
-This is a pre-cut kit and it includes two small vacuum "T"s for the hoses.
- Replaces: This kit replaces all the vacuum lines under the hood. It also includes an extra twelve feet of hose to allow you to replace your radiator overflow and windshield washer hoses if desired. This is a pre-cut kit and it includes two small vacuum "T"s for the hoses. It's very important to have leak free hoses and connections on the supercharged 3.8. Now that they are old, the factory hoses often leak under boost causing incorrect pressure signals to reach kit the map sensor, fuel pressure regulator, and the supercharger's bypass solenoid and bypass actuator. If your supercharged 3.8 is a little low on power, or has higher than normal fuel consumption or emissions this kit will probably help.
-500F heat resistance, I00 psi without collapsing under pressure.
-Makes I80 degree bends inside itself.
Available in Red, Black, Silver, Yellow, and Blue.
