[Zmagnette] leak at fuel line float bowl connection

[Steven Trovato]

My Magnette recently decided to spit fuel out of the overflow on the 
rear carb.  The floats were fine, but I took the opportunity to 
replace both floats with the new nitrophyl type.  I also replaced the 
needles/seats with new spring loaded viton tip kind.  I used new 
gaskets and washers from a rebuild kit.  When I got everything back 
together I had a leak between the float bowl lid and the fuel line 
banjo fitting.  I took it apart again and carefully rubbed the mating 
surfaces using emery cloth on a piece of glass.  With this treatment 
and tightening the bolt with a lot of force, I finally get it all 
back together with no leak.  Before anyone asks, yes, the banjo 
fitting is the right way around, with the recessed side facing the 
bolt head.  The washers provided in the kit are not very thick and 
they are pretty hard.  Is this what everyone uses here?  It seems 
like there should be something a little thicker and more flexible.
