Air in fuel line of glow engine
by Rob
(Chandler, AZ)
Hello again.
I noticed that I have air bubbles in the fuel line before and after the carburetor. After reading some past posts, I followed a suggestion and submerged my tank under water and blew through the crab line and then muffler line to see if I get any air bubbles.
Sure enough I got some. Although very small I would like to eliminate them.
The problem for me is that the air is coming through the rubber plug openings where the brass tubes come out. I am not sure what to use to seal it/them.
First I thought I would use window caulking but would nitro fuel eat through that???
Second idea was 5 min epoxy, but that turns solid when it dries. Would the vibrations break apart the bond between rubber and brass???
Or should I buy a new rubber plug??? Any ideas??
