MEP-005a fuel leak

[shanekarl]

I have noticed a fuel leak 1-2 drops per minute even when the generator is off from the following part. (Circled in photo)

I am not sure what this is, photo attached - it does not seem to be anything I can tighten up so looking for advice about how I might fix this or what to look at.

thanks I’m advance

Hi Shane, That knob is the droop adjustment knob. You don't want to turn that at all.
The knurled knob pulls off and there is a small o-ring underneath, but it won't come off without removing the rear end cap which is held on by 4 small cap screws. There is also an O-ring where the control rod guide screws into the body of the pump, ( #77 ) but if it appears to be leaking from under that knurled cap I would bet item# 74 in the picture is leaking.

I've rebuilt a few of those IP's and have some parts around. I may have the O-ring you need, or a complete seal kit is about $35 on ebay.

If you remove the end plate, that houses the thrust plate for the internal transfer pump.
When you reassemble it, make sure the alignment pin is lined up correctly with the hole in the body and the notch in the thrust plate before you tighten the screws. Also make sure the O-ring that seals the end cap to the body is seated in it's groove correctly.
