Title: Fuel leak...
Post by: Iver on April 19, 2009, 12:59:31 AM
Well, I finally got around to starting up the coach today.  After sitting since last October my newly rebuilt 8-92 fired up right away. Good!  So I decided to back it out of the shop and maybe take it for a spin.  As I was backing out, I was watching the driveway and apparently I was leaving a trail of drops of some liquid.  Not Good! I quickly returned the coach back in the shop and went back to the engine and noticed fuel dripping from a fitting supplying fuel to the left bank.  A brass adapter from pipe thread to flare had a crack all along the side.  Curious that there was not a leak in the system when I put it away and now one simply developed.

I don't have a problem with changing the fitting, but will I lose prime by disconnecting the line to change the fitting?  Will it help to close the valves on each side of the fuel filter?
            Thanks,  Iver.

Iver,
   I changed a similar fitting on our 8V71 the other day (on the right cylinder).  I picked up the new fitting and had it ready. I started the engine let it run about 1 minute and shut it off. I removed the line, changed the fitting, re-connected the line and immediately started the engine back up.  It never missed a lick.  YMMV
   Over the years, I have replaced several brass fittings that have cracked. I think this occurs due to the fittings being overtightened and fatigue in time.   Jack
