<VV> Help needed Silver solder fuel fittings

[Paul Michalczyk]

I'm making up some fuel fittings for a fuel injection system and need to 
make up a Tee fitting for a fuel return. I would like to silver solder 
some brass bits together. Will today's crummy gas affect the solder? I 
can silver solder but brazing (my preference) would have to be done by 
someone far away. The solder would not be the sole means of mechanical 
connection, but will add support and sealing. Thanks.
