10.3 Fuel Pump Installation
DANGER! NEVER GET UNDER A VEHICLE SUPPORTED ONLY BY A JACK. SERIOUS INJURY OR DEATH CAN
RESULT FROM VEHICLES FALLING OFF OF JACKS. BEFORE WORKING UNDERNEATH A VEHICLE,
SUPPORT SOLIDLY WITH JACK STANDS.
Most in-line high-pressure fuel pumps have limited suction characteristics, so they need to be mounted as low as possible and
should be mounted no higher than the bottom of the fuel tank. The pump can be mounted either horizontally or vertically. When
mounting the fuel pump, check to make sure that you have the fuel flow in the correct direction. This may sound like a foolish
reminder, but it is a common installation error. To prevent damage to the fuel pump before the fuel system is filled with fuel,
drip/spray some light lubricant (such as 10w motor oil) into the inlet side of the pump.
1. Make sure fuel tank is properly vented.
2. Mount the electric fuel pump as close to the fuel tank outlet as possible. Mounting the fuel pump in this manner will insure
that the pump will prime easily and purge fuel vapors in the fuel lines to insure faster starts.
DANGER! TAKE PRECAUTIONS TO ENSURE THAT ALL FUEL LINE ROUTINGS ARE AWAY FROM HEAT SOURCES,
SUCH AS THE ENGINE, CATALITIC CONVERTER OR EXHAUST PIPES. A FIRE OR EXPLOSION HAZARD
COULD CAUSE SERIOUS INJURY OR DEATH.
DANGER! ENSURE THAT THE FUEL PUMP MOUNTING LOCATION WILL NOT INTERFERE WITH ANY UNDER THE
VEHICLE COMPONENTS, ESPECIALLY AT THE EXTREME LIMITS OF THE SUSPENSION TRAVEL. A FIRE
OR EXPLOSION HAZARD COULD CAUSE SERIOUS INJURY OR DEATH.

Connect the pump to the tank using 3/8” I.D. fuel hose. Connect the outlet of the pump to the steel line which runs to the
front of the vehicle with 3/8
” I.D. fuel hose, depending on the diameter of the steel fuel line. All fuel hose used must meet
SAE J30 performance standards.
10.4 Fuel Line Mounting
DANGER! FAILURE TO USE A FUEL HOSE THAT MEETS SAE J30 STANDARDS COULD RESULT IN FUEL LEAKS. A
FUEL LEAK MAY RESULT IN A FIRE OR EXPLOSION HAZARD, WHICH COULD CAUSE SERIOUS INJURY
OR DEATH.
1. If using existing fuel lines, inspect and replace any hose, clamps, or fuel line showing any sign of aging or does not meet
SAE J30 fuel hose specifications. If you are not using existing fuel lines, you will need a fuel line routed to and from the
engine compartment and fuel rails. Use a 3/8
” steel fuel line available at any auto parts store. All steel fuel line must meet
SAE J526 standards.
Any time a rubber hose is connected to a steel fuel line, the steel fuel line must have a “barb” or
“nipple” on it to properly retain the hose (along with hose clamps). Either use the proper tool to put a “nipple” on the end of
the tube (similar to the ends of the fuel filters), or use a compression fitting and a barded fitting adapter that is the proper
size for the lines used. Clamping a rubber hose to a steel line that has the end squarely cut off does not ensure a safe
connection.
DANGER! FAILURE TO USE STEEL FUEL LINE THAT MEETS SAE J526 STANDARDS COULD RESULT IN FUEL
LEAKS. A FUEL LEAK MAY RESULT IN A FIRE OR EXPLOSION HAZARD, WHICH COULD CAUSE SERIOUS
INJURY OR DEATH.
DANGER! TAKE PRECAUTIONS TO ENSURE THAT ALL FUEL LINE ROUTINGS ARE AWAY FROM HEAT SOURCES,
SUCH AS THE ENGINE, CATALYTIC CONVERTER, OR EXHAUST PIPES. A FIRE OR EXPLOSION HAZARD
COULD CAUSE SERIOUS INJURY OR DEATH.
DANGER! RIGID FUEL LINE TUBING SHOULD BE USED FOR UNDER VEHICLE RUNS, SUCH AS ALONG VEHICLE
FRAME RAILS OR UNDER FLOOR PANS. FAILURE TO DO SO IS A POTENTIAL FIRE OR EXPLOSION
HAZARD, WHICH COULD CAUSE SERIOUS INJURY OR DEATH.
2. Anchor all fuel lines securely to solid chassis members at 1 ½ foot intervals using rubber coated steel clamps. Use of only
approved steel fuel line tubing will afford maximum fuel line protection against road hazards, gravel bombardment and
premature wearing due to flexing, temperature extremes, road salt, weather, etc.
10.5 Fuel Filters
WARNING! It is very important the fuel filters have the proper flow capacity, burst pressure rating and filter size. The
flow capacity of the filters must at least 60 gallons per hour (gph), and the filter size must be no bigger
than 10 microns for the high fuel pressure filter and not bigger than 75 microns for the fuel pump inlet
filter. The high-pressure fuel filter should be rated for at least for 150 psi burst pressure.
