6. Lubricate the external O-ring on the valve using mineral oil or other suitable lubricant.
7. Install the WPLLD valve [Figure 4-2] in the Mechanical LLD pump port.
IMPORTANT! Do not overtighten the valve when installing into the pump. Overtightening the valve can cause it to
stick resulting in a flow restriction in the line! Seal the NPT threads only with a UL-classified non-toxic thread seal-
ant suitable for the fuel involved.
