WARNING: MSD’s Push-Lock fittings are designed for
use with the MSD fuel hose only. Do not use
the MSD fuel hose with other fittings. Do not
use MSD Push-Lock fittings with other fuel
hose. Compatibility issues may cause fuel
leaks. Fuel Inlet Fittings and Cross-Over
Line: LS engines require a cross-over fuel
line to route the fuel from one bank to the
other. This is typically done at the front of
the engine. Due to the variety of intake
manifolds and accessories a cross-over
line must be made for each application.
The supplied MSD Push-Lock AN fittings
are designed only for use with the supplied
fuel hose (Aeroquip AQP FC598). We
do not recommend mixing Push-Lock
style fittings and hoses from different
manufacturers. Doing so may result in
fuel leaks and expose other dangerous
incompatibilities.

MSD supplies a length of fuel hose and two 90° -6AN
fittings to prepare a fuel crossover line. The fittings utilize
Push-Lock technology and are designed exclusively for
use with the supplied hose. These fittings do not use
clamps, however it is imperative to follow the installation
instructions.
Proper installation begins with a clean, square cut of
the hose. A hose cutting tool or new razor blade are
recommended. When installing the hose it is important
that the hose is pushed on all the way to the thin beauty
ring (Figure 20). This means the hose should fully overlap
the inboard barb. Too little engagement, as well as over-
engagement, will result in a compromised connection that
is prone to failure.
1. Determine the length of hose needed. Mark the hose
and cut it using a hose cutter or new razor blade.
There should be minimal disturbance of the outer
jacket, braids and inner liner. The cut plane should be
perpendicular to the hose axis. (Figure 21).
2. Before installing the hose to the fitting, it is important
to anchor the fitting. Proper installation cannot be
achieved by holding the hose and fitting in your hands.
For best results, the hose should be installed with
minimal twisting or pausing.
3. Apply a light coat of oil to the barbs on the fitting and
to the inside of the fuel hose. Use care not to get oil on
the outside of the hose as it will be impossible to get a
firm grip on the hose.
4. With the fitting anchored securely, push the hose over
the barbs. The hose is properly installed when it is flush
with the thin edge of the beauty ring (Figure 22). At this
point, the hose end should have rolled over the inboard
barb.
