LPG Fuel Systems

Regulator Drain Plug

Preventative Maintenance

The regulator is preset at the factory and generally

requires no further adjustment. No periodic service is

required. Over time, depending on fuel quality, operating

environment, and system performance, fuel deposits

can accumulate inside the regulator. Those regulators

containing a drain plug (Nikki) should be drained every

500 hours to remove any accumulated deposits. See

Figure 5A-23.

Figure 5A-23. Regulator Drain Plug (some models).

1. Turn supply valve off, run engine out of fuel, and

turn off ignition switch.

2. Disconnect and ground the spark plug leads.

3. Remove the 1/8" pipe plug from bottom of

regulator and drain any accumulated deposits.

See Figure 5A-23.

4. Reinstall plug using pipe sealant with Teflon

(Loctite

592 or equivalent) on threads and tighten

securely. If required, a replacement plug is

available as Kohler Part No. X-75-23-S.

Regulator Service

Every 1500 hours it is recommended that

disassembly, cleaning, and resetting of the regulator

be performed using the regulator rebuilding kit

available. Specific instructions are included in the

rebuilding kit. Perform the regulator service following

the instructions provided. As all adjustments and

settings must be reset using specific test equipment,

this must be performed by qualified LP personnel only.

the regulator every 1500 hours, or whenever cleaning

and servicing is required.
