"I'm going to repost yhis to see if the forum will reconise my changes.
I notice my 40 chokes down if I leave it @ idle. Sounds like a giant hand is slowly squeezing it slower & slower, until it stops. Filter is clean, hatch is open & drive is in neutral. If I increase throttle a bit, it stays running & doesn't sound like it's laboring to do so. Is this the correct proceadure? Fast idle, THEN cut back?
We just completed a 1,000 mi. trip & had no issue with morning idle then.
My concern is this may be an indication of a bigger problem. I don't want to ignore it.
Thanks, Ted"
 
"Disconnect the fuel return li

"Disconnect the fuel return line and let it run into a cannister. If fuel return disappears and engine stops, either too much resistance on suction side or air getting in.It might even be a matter of the fuel pump itself. If engine keeps running without problem -too much resistance in return line somewhere. (Line bent/blocked)."

I have dual tank setup. Can I do this 1 tank @ a time?"
