9. Because Mallory’s Return Log is a return-style regulator,

the bypass at the pump must be disabled. If you are using

a pump with an external bypass (such as Mallory 250 or

500 pumps), place a plug in the bypass outlet.

If you are using a Mallory 70, 110, or 140 pump, the by-

pass spring must be replaced with the bypass spacer in-

cluded with this Fuel Log (See Figure 2). Replace the spring

with the spacer. Apply thread sealant to the bypass plug

and tighten the plug until snug. Do not overtighten. Re-

place and tighten the jam nut (See Figure 2).

If you are using a non-Mallory pump, contact the manufac-

turer for information on how to disable the bypass.
