Notes:
To install, simply locate a factory vacuum hose leading from your intake manifold. Cut the hose and splice in a "T"fitting. Run nylon tubing from the T fitting back to the VDO gauge.
Requires nylon tubing and 1/8"NPT barb adapter, sold separately. VDO nylon tubing kit is available from NEUSPEED. 1/8"barb adapter can be found at most auto parts stores.
