WARNING: PLEASE READ ALL INSTRUCTIONS BEFORE PROCEEDING. PROFLOW WILL NOT
BE RESPONSIBLE FOR ANY DAMAGE AS A RESULT OF THE INCORRECT INSTALLATION OF
THIS PRODUCT. IT IS RECOMMENDED THAT A QUALIFIED AUTOMOTIVE TECHNICIAN
PERFORMS THIS INSTALLATION.
Description:
Proflow Performance’s mechanical belt driven fuel pump utilizes o-ring sealed -10AN ports
which do not use thread sealant. It is recommended only to lubricate the o-rings on your fittings
before use.
A 100 micron fuel filter is recommended to be installed between the fuel tank and fuel pump
inlet as well as either a 10 or 40 micron fuel filter after the pump outlet (PFEFS301B).
Ensure this pump has a good gravity feed from the fuel tank to ease priming. A minimum fuel
line supply and return size of AN10 is recommended. A high flowing fuel pressure regulator is
highly recommended (PFEFS13110 or PFEFS13113).

PROFLOW LIMITED WARRANTY
This Proflow product is warranted to be free from defects in materials and workmanship for a
period of one year from the original date of purchase. No warranty claim will be valid without
authentic, dated proof of purchase. This warranty is to the original retail purchaser and none
other and is available directly from Proflow and not through any point of distribution or
purchase. 2
Typical Installation:
This mechanical fuel pump should be mounted as low as possible on the vehicle to ease fuel
pump priming. The fuel pump should turn at roughly half of the engine speed. It is
recommended that a 28-tooth pulley on the pump and a 14-tooth pulley on the crank shaft is
used.
1. Relive the fuel system pressure and disconnect the negative battery terminal from
the battery.
2. Find a suitable place on the engine to mount the Proflow fuel pump. Make sure the
location of the pump is clear of all hot engine components and is clear of any other
moving drivetrain components.
3. Determine which direction the fuel pump shaft will rotate. The direction that the shaft
is rotating will determine which port is the inlet and which is the outlet. Using the
below example figures as a reference, identify the inlet and outlet ports.
If the fuel pump shaft is rotated in a clockwise direction as viewed fro the rear of the
pup, the inlet and outlet ports wil be as shown in Figure 1a. If the fuel pump shaft is
rotated in a counter clockwise direction, the inlet will now becomes the outlet as seen
in figure 1b.
4. Connect the fuel cell to the fuel filter inlet with a minimum hose size of AN10 and
then connect the fuel filter outlet to the fuel pump inlet.
5. Connect the fuel pump outlet to the vehicles fuel system while using either a 40 or 10
micron size fuel filter.
6. Turn the engine over without starting the engine to allow the fuel pump to prime for a
few seconds and check the fuel pressure. If there is no fuel pressure, wait 60
seconds and then turn the engine over again until there is fuel pressure detected.
