For Proper Installation follow the listed instructions.
• Use 37 o JIC flare fittings.
• Use a non-hardening thread sealing compound.
• Prefill (prime) the pump on long runs to reduce dry running time.
• Check all unused pump fittings for tightness.
• Bleed system. Open bleed port approximately one turn.
Bleed for 15 seconds after clear oil begins flowing out of port.
Close bleeder valve tightly
• See page IV-1 if pump fails to prime or deliver
It is suggested that you DO NOT do the following:
• Install by-pass plug. (Will damage seal.)
• Use compression fittings. (Will eventually leak.)
• Use Teflon tape. (Will void warranty.)
• Use check valves. (Especially on gravity feed systems.) See Thermal Expansion, page III- 12.
• Exceed 10 psi (manufacturer) or 3 psi (NFPA) inlet line pressure.
• Exceed 6" hg. running vacuum (for Suntec “A” and “B” fuel units) or 2" hg. running vacuum (for Suntec “J” and “H” fuel units).

One pipe installation:
The by-pass plug must not be installed.
The excess fuel is returned back to the inlet.
Two pipe installation :
The steel plug of the return port must be removed, and the by-pass plug must be inserted in the return port, allowing excess fuel to be bypassed back to the tank.
The return plug must not be reinstalled.
Bleed : In one pipe operation, the easy flow bleeder valve must be loosened to bleed the system.
Bleeding in two pipe operation is automatic, but it may be accelerated by loosening the easy flow bleeder.
The by-pass plug must not be installed.
The excess fuel is returned back to the inlet.
