VANS HAS A KIT WHICH ALLOWS YOU TO PRESSURE TEST YOUR TANKS WITH COMPRESSED
AIR. I USED IT AFTER FINISHING UP MY TANKS SEVERAL YEARS AGO - IT'S
CLASSIC VANS - ECONOMICAL AND SIMPLE AND IT WORKS. YOU SIMPLY MAKE SURE THE
FILLER CAPS ARE NICE AND TIGHT; SCREW A NIPPLE INTO THE VENT LINE FITTING
AND TAPE A BALLOON OVER IT; SCREW AN AIR VALVE INTO THE FUEL LINE FITTING
AND PUMP SOME AIR INTO THE TANK WITH A BICYCLE PUMP - DO NOT USE AN AIR
COMPRESSOR. THE BALLOON WILL EXPAND AND KEEP YOU FROM OVER PRESSURISING THE
TANK. DISCONNECT THE PUMP AND WATCH THE BALLOON. I ALSO BRUSHED SOAPY
WATER ONTO ALL THE RIVET LINES. IF THE BALLOON STAYS INFLATED AND YOU DON'T
SEE ANY BUBBLES - YOU'RE HOME FREE. SURE BEATS FOOLING AROUND WITH 21
GALLONS OF GASOLINE - AVGAS OR MOGAS. I'VE NEVER HAD A LEAK.

Thanks Dan, as I indicted before we did the balloon test several years ago
, but we also know of several fellows that were successful at that test an
d had leaks when gas went in the tank later. Before I spend a bunch of mo
ney on painting and time and effort I want assurance the paint won't be ru
ined by a leak. So who knows can we expect Mogas to move through a leak as
100 LL ? Who knows? Bill

We are planning on a full up test of the RV-8 tanks before final mounting.
Instead of 21 gallons of 100 LL we were thinking maybe just premium mogas
. Will mogas be a suitable substitute for AV gas? Will it show a leak as
well as 100 LL ? We know water viscosity is too great, but mogas it avail
able, easier. What does the smart folks think?, Best regards, Bill
