as illustrated. With the vacuum gauge mounted on the outlet side of the

filter, the gauge will indicate any suction line restriction including a dirty

filter. A pump inlet manifold is supplied for direct connection of the filter

to the inlet of the pump.

The 50 psi relief valve supplied with the pump and a return line of 1/8”

NPT black iron pipe must be installed as illustrated.

The discharge line between the valve on the outlet side of the fuel pump

and the heater should be 3/8” O.D. copper tubing with a minimum of 1/32”

wall thickness with 45° flare fittings. The discharge line must continually

rise. A lift height of up to 15 ft (4.5 M) is acceptable with a maximum total

length of 60 feet (18 M) of tubing.

Do not install manual valves in the supply line.

Connect the fuel line to the heater at the connection on the corner of the

service tray.

All piping should be protected from possible damage and be rigidly fas-

tened in place in a workmanlike manner. Do not use TEFLON

based pipe

dope or TEFLON

tape at the connections in an oil line. Use an oil-resis-

tant pipe dope. Do not use union connections in the suction line (line be-

tween the oil supply and the remote pump).

NOTE: Care must be exercised to ensure airtight connections.
