I own a 2003 Regal Commodore , twin gas 4.3 Owing over a year .
Burping issues has plagued me on/off during this time .
Fueling very slowly , seems too help but time has come too resolve this dangerous issue
I am retired and use my boat 3 times a week, local waters .
I top off often
Filling slowly , holding fuel handle at all times.
Filling slowly helps, but at times fuel burps . Indication is while I am fueling it will shut as if its full. Knowing it is not, I back away and the fuel shoots out all over swim platform .
THIS IS WHAT I HAVE DONE
On the regal vent line stands alone . Filler hose & two gas lines for engines
Vent line clear .
Was removed, re- installed , blowing air thru. Hull vent cap is also clean & clear
Thinking the L shaped fitting that mounts into fuel tank and connects vent hose,
Obstruction once loosed can not come up & out . That fitting has no ball just a vent connector, and leaving it alone
Other day while fueling, started too burp, I was able too look into engine room and at tank & hoses and nothing was expanding ?
FUEL FILLER CAP
a small threaded extruding piece of metal just before the rubber gas hose connects gas cap with a chain
This piece stops the fuel nozzle from going all the way into the fill
Hose only goes in a inch or so,
My thinking since its not all the way in air could be getting into line with fuel ???? causing the burping ???
Biggest issue is movement & ability too see and fix anything in engine room, but yesterday while poking around and moving gas hose felt a softer area within the black rubber fuel hose ?? Was not at a bend , might have been at one time and the softer area is causing the burping ?? SOME THOUGHTS
