Vortech Maxflow Fuel System - Manual (Page 4)

C. Fuel pump and fuel filter mounting/Feed hose, (cont'd.)
minimum bend (the hose length may need slight trimming so
that the hose remains straight when it is installed onto the
filter with 90
°
hose end).
•
Using the filter bracket as a guide, mark two spots where the
holes are to be drilled to mount the filter bracket. Centerpunch
and drill the marks with a .14 drill. Mount the filter and bracket
to the body using the two supplied #12 hex head sheetmetal
screws.
•
Orient the filter assembly so that the Y-block sits vertical
and points toward the center of the vehicle (see schematic).
•
Remove the -10 x 90
°
hose end from the filter inlet and slide
into the -10 hose coming from the tank pickup. Reattach the
90
°
hose end and hose to the filter inlet and secure.
6. Cut two 6” lengths of the supplied blue "push-on" -6 hose and
attach one end each to two of the supplied -6 x 45
°
"push-on"
hose ends (see outlet side of filter in schematic). Attach both
of these hose assemblies to the -6 fittings on the filter Y-block.
7. Attach the T-Rex fuel pumps to the supplied pump mounting
bracket using the pump clamps and #10 x 1/2” bolts, nuts and
washers (see schematic for proper orientation).
8. Temporarily position the pump bracket assembly up to the
rear/outer spare tire well to allow points to be marked for
mounting holes. Using the rear bumper as a reference,
center the pump assembly (left to right) in the car. Also make
sure that the pumps are located in the proper vertical (up and
down) position (see Photo 3). When the pumps are properly
positioned, the center of both pumps together must line up
with the fuel filter centerline (see schematic). With the
pumps in position, mark and center punch the four mounting
holes. Drill through with a 3/16” drill.
9. Attach the four supplied rubber isolator mounts into the four
remaining holes in the fuel pump mounting bracket (opposite
side of the bracket from the fuel pumps) using the #8 nuts and
washers. Mount the pump bracket assembly to the outside
rear spare tire well through the previously drilled holes (make
sure that the rubber mounts are sandwiched between the
body and the mounting plate) and secure with the # 8 nuts
and washers from the inside of the trunk.
10. Slide the two blue "push-on" -6 pump inlet hoses onto the fuel
pump inlet fittings. Trim the hose length if necessary. Secure
hoses with the two supplied # 4 hose clamps.
11. Cut two 7” lengths of the supplied -6 hose and attach one end
each to two of the supplied -6 x 120
°
hose ends (see outlet
side of fuel pump in schematic). Attach both of these hose
assemblies to the -6 fittings on the discharge side of the fuel
pumps.
NOTE: Marking and drilling the four mounting holes
may be done two ways. (1) Remove the bumper
cover and bumper and then mark and drill using the
bracket as a template. (2) Mark two holes on the
outside of the spare tire well with a scribe or felt pen
and then measure from the outside floor bottom to
the mark. Using that same measurement, but from
the inside floor bottom, mark the four holes by using
the pump bracket as a template.
