7/32" X 72" length of new OEM replacement vacuum tubing for 1984-1987 Buick Grand National, Turbo Regal and 1987 GNX.
This tubing is a special rubber polymer made to factory original GM6148-M specifications for composition, pressure handling, durability, fuel and oil resistance. It has the highest pressure rating of any non-reinforced vacuum tubing we have found. This unique, hard to find tubing is not available at any aftermarket auto parts sources that we are aware of.
Another outstanding product only sold by Highway Stars.
NOTE* This is NOT SILICONE and will not tear or blow off under boost pressure like silicone.
