When we took out the fuel bowl for my brothers HPOP the bottom had a very gray, milky looking liquid in the bottom of the bowl. Then it looked as if there was a lot but small pieces of gravel in the bottom of it. Is this normal or should he get something looked at or new? Thanks guys.

 

Not uncommon, just crap from the tank. Id clean the bowl if i was you and change the filter.

 

Ok ... thanks man.
