VFF30 LOCKOFF/FILTER
REPAIR KIT INSTRUCTIONS
Important: Any maintenance, service or repair
should be performed by trained and
experienced service technicians. Proper tools
and equipment should be used to prevent
injury to the servicing technician, property or
system components. Service repairs should
always be performed in a safe environment
and the technician should always wear
protective clothing to prevent injury.
The IMPCO PPI-4-116 repair kit instructions
will provide the technician information to
successfully repair the VFF30 Lockoff. Always
inspect the major casting pieces for damage,
corrosion or cracks before attempting a service
repair. Be sure the repair kit part number you
are using is correct for the Lockoff being
serviced. Diaphragms are color coded and
have different performance characteristics:
BLACK: Hydrin diaphragm material is the
standard material and is well suited for the
most common applications.
YELLOW: Silicone diaphragm material is the
optional upgrade material that provides
excellent flexibility in cold weather climates
and is more resistant to chemical
contamination.
BLUE: Fluorosilicone diaphragm material
provides excellent high and low temperature
durability with increased chemical resistance.
This material is recommended for turbo
applications.
Do not use Teflon tape to seal any fuel fittings.
Failure to follow this warning may cause
internal leaks resulting in serious injury and/or
property damage.
