| H-SERIES FUEL TRANSFER PUMPS
INSTALLATION AND OPERATION MANUAL
Do not use additional check valves or foot valves unless they have a proper pressure relief valve built into them.
Please be aware that additional check valves will reduce flow rates.
A pressure-retaining fill cap can be used to reduce fuel loss through evaporation.
Threaded pipe joints and connections must be sealed with the appropriate sealant to prevent leaks.
Use caution to prevent cross-threading during installation which can cause damage to either or both the inlet flange
as well as storage tank bung.
In all tank applications, be sure the tank is properly secured per tank manufacturer’s guidelines.
Installation
Your Fill-Rite pump is designed to be mounted on a fuel tank via a threaded inlet flange supplied with the pump. Typical installations are shown in Diagram 1
and 2. Your pump features an integral bypass valve to recirculate the fluid when the pump is operating with the nozzle closed.

Stationary Tank
For stationary fuel tanks, the pump mounts to the tank bung by way of
the pump inlet flange. Given the different sizes of stationary fuel tanks,
a custom suction or inlet pipe may be necessary. We recommend 1” NPT
black iron pipe that is extended to a length of at least 1-2” from the
bottom of the tank, with the bottom of the pipe cut to an angle between
30-45 degrees for improved flow.
A stationary tank must be equipped with a vent cap. (Diagram 1)
Mobile Tank
For mobile fuel tanks, the pump mounts to the tank bung by way
of the pump inlet flange.
For Telescoping Steel Suction Pipe
Allow telescoping tube to extend fully to the bottom of the tank.
For Custom or PVC Suction Pipe
To avoid penetrating the tank, we recommend leaving a minimum of 1-2”
of the pipe off the bottom of tank. We further recommend cutting the
suction pipe to a 30-45 degree angle for improved flow.
The mobile tank must be equipped with a vent cap. (Diagram 2)
