Tech Tip- Slipping Boost Hoses

[PeterT]

Lately we have had a number of vehicles in our installation department that have experienced problems with a loss of boost due to slippage or complete loss of connection of the boost hoses. This is not just on those vehicles with aftermarket enhancements, but also on vehicles that are stock, sometimes brand new!

I thought it might be helpful to offer a tech tip for those that experience this problem. If a hose joint has come loose on your truck, remove the silicone connecting hose and the adjoining tube from the vehicle. Clean any oily residue from the hose and the tube with a non-oil-based cleaner such as acetone. An oil based cleaner such as solvent will leave an oily residue which can allow the slippage to occur again. Rough the surface of any painted components with sandpaper before reassembling. On particularly troublesome hose joints, a coating of Gaskacinch or weatherstrip adhesive may be helpful, although this should be considered a last resort, since you would most likely destroy the hose the next time it needed to be disassembled.

It is also a good idea to check all the hose clamps at each hose joint on occasion. The hoses can take a set and the hose clamp can wind up somewhat loose on the hose.

Hope this is helpful to someone who has had this problem before.
