2. FUEL PUMP ASSEMBLY:
With fuel pump assembly
on bench, loosen and slide
up the lower plastic clamp
on top of fuel pump. Now
disconnect the electrical
connection.
On the bottom of the fuel pump there is a fuel strainer sock. Make
note of the orientation of the fuel strainer sock on the stock fuel
pump so that you can attach the supplied fuel sock in the same
orientation on the new pump. Remove the strainer sock.
Use a small flat blade
screwdriver to gently pry
around strainer and it
will pop off.
Carefully
slide the factory fuel
pump out of the
assembly.
Install the
new fuel pump supplied
in the kit into this
assembly.
NOTE: There is a kit supplied with the new fuel pump. Install
the 3" length of fuel hose onto the 3/8" steel tubing where the
old fuel pump junction hose was previously. Use the 3/8" hose
clamp to secure hose to steel tubing. The fuel line will be a very
tight fit over the 3/8" tubing. It may be necessary to lube the
tubing with some spray lubricant to ease hose installation. You
must use the supplied 3” length of hose. DO NOT use the stock
rubber fuel hose.
Slip the 5/16" clamp
over the rubber hose,
then insert fuel pump
barb into hose and
secure with 5/16"
clamp. Be sure there
is adequate clearance
between the metal
hose clamp and the
electrical connections
on the pump.
Some shortening of the rubber hose may be
necessary for proper alignment of the pump with the pump hanger.
Use the new rubber base gasket for fuel pump. If the big O-ring in
fuel tank is OK, (not torn) you may reuse it. If necessary, replace
with original equipment O-ring from a GM dealer. Make sure to
grease large O-ring with
white grease or
equivalent.
Making
sure clamp is tight and
electrical connector is
connected, install the
new strainer sock into
same position as noted
earlier. It will push on
by hand. No tools are
required.
Install the complete
assembly back in the
fuel tank.
Make sure
you don’t bend anything
while reinstalling. Lock
assembly back in place
by rotating lock ring
clockwise until it hits its
stops. Now tighten fuel
connections and hose
clamps. Make electronic connection and ground connection. Re-
install fuel tank (Suburbans, etc.). Do not re-install bed on pick-up
trucks at this time.
See Performer Multi-Point Fuel Injection installation
instructions for remainder of system installation.
Alternate Procedure: Lowering the Fuel Tank
Suburbans (or trucks that you cannot remove the bed), require
removal of the fuel tank(s). The fuel tank must be lowered from
beneath the vehicle. First drain the fuel, then disconnect the
ground wire and the weather pack electrical connector. Then
disconnect gas fill hose and vent hose.
Let the tank drop enough to gain access to the fuel lines, then
disconnect fuel lines and remove tank from vehicle. Most
tanks have two mounting straps which must be removed.
