Gas bubbling in clear filter

Post by oldfrogdiving »

Ok gentlemen here is a slight issue I have just uncovered in my 66 D200 slant 6 carter single BBL, Np 435, I have been driving all morning stop and go traffic, no problems no overheating, when I got home I was doing a routine oil check (slightly below full) and I noticed the clear fuel filter bubbling. I checked my water level its topped off and not low, no water seepage from pump, belt tight, fan Aok, I'm running my stock oil bath type cleaner. I have never noted this, the truck is running fine and its about 85 degrees here today its winter you know? I have never noticed this before but cant imagine its normal, I fired it up and checked for water circulation which has never been high volume. I do have a replacement water pump. As usual your thoughts appreciated.
Thanks
Frog

Engine heat boiling the gas. No problem, unless it boils completely into vapor, then u have "vapor lock".
