INSTALLATION INSTRUCTIONS

AND TECHNICAL INFORMATION

RETURN LOG

PART NO. 4302

1. Mallorys fuel return log features a built-in adjustable return

regulator. The pressure can be adjusted while the engine is

running. There are no shims to change and the fittings do

not need to be loosened to adjust the pressure. The pres-

sure is adjusted by loosening the jam nut and turning the

adjustment screw.

2. Fuel pressure is adjustable between about 3 PSI and 12

PSI. Exact range depends on the size of the fuel pump and

return line size.

3. All fittings are included. The center-to-center distance of the

outlets is adjustable to allow use on most Holley carbs.

4. Thread sealant may be necessary on the 3/8" NPT fittings

and on the 1/8" NPT gauge ports.

5. Repair kits are available and include all necessary O-rings.

These kits can be used for repair, or to convert from gaso-

line to alcohol or from alcohol to gasoline.

Use Kit #3173 for gasoline applications.

Use Kit #3174 for alcohol applications.

Lubricate O-rings prior to assembly.

6. If AN-8 (or 1/2" hardline) fuel lines are used, the AN-10 fitting(s)

can be replaced with AN-8 fittings (such as Earls PN 985081).

7. Assembly is shown with the inlet at the rear of the carb. As-

sembly can be flipped over so that the inlet is near the front.

IMPORTANT NOTE

This fuel log is assembled with o-rings for use with gaso-

line. O-rings are also included for use with alcohol fuel. If

you use alcohol fuel, disassemble the Mallory Return Log

and replace the installed o-rings with those supplied.
