F. Final Check/Reassembly
1. With all hose fittings connected and secure, “key-on” the ignition
several times in sequence or until normal fuel rail pressure is
reached (35-45 psi). Thoroughly check over the entire installa-
tion for fluid leakage. Make sure that all fuel injectors are dry
where they are inserted into the fuel rail.
2. Check that all hoses are routed securely away from heat and
sharp corners. Do not allow fuel lines to chafe/rub on each other
or anything else. Find and correct any problems or leaks.
3. Reinstall the intake manifold and other components that may
have been removed before installation.
4. Start and idle the vehicle. Double check the installation for fluid
leaks.

Supplement for Stainless steel braided hose/hose
end assembly
(only for use with stainless steel hose and hose ends)
1. Wrap the hose tightly with electrical tape at the center of the cut
location (this minimizes braid flare when cutting). Cut the hose
square (through the center of the tape) using a thin, high speed
cut-off wheel (best) or fine tooth hacksaw. Remove the tape after
cutting being careful not to fray the braid.
2. Slip the cut hose end into the hose end socket (socket must be first
separated from the nipple portion of the hose end). Use a twisting,
pushing motion until hose opening is in line with the back of the
threads inside the hose end socket.
3. IMPORTANT - Mark the socket base where it meets the hose with
a felt pen. This mark will later let you know if the socket has pulled
out during hose assembly in the next few steps.
4. Liberally lubricate the nipple threads and inside of hose with 30 wt.
oil. While gently holding the socket and hose assembly in a vise
and by hand, carefully insert the nipple into the hose. Turn
(clockwise) the nipple by hand into the socket and hose to engage
the nipple and socket threads. Make sure hose does not push out
of socket by observing the mark made in previous step. Thread
the nipple in by hand as far as possible. Make sure threads are
mated properly and not crossthreading.
5. Using a wrench, complete the hose end assembly. When properly
assembled, a small gap of .030 or less should exist between the
socket and the shoulder of the nipple.
6. IMPORTANT - Check the pen mark made on hose in step 3 for
hose pushout. Hose assembly should be cleaned and tested to
twice the maximum operating pressure. Hose should also be
double checked at time of installation for leakage under normal
operating conditions.
