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 ________________________________ Message 2 _____________________________________ Time: 12:02:39 PM PST US From: "Vince Himsl" Subject: RE: RV8-List: Fuel Tanks Testing 100LL has a blue dye that really helps in isolating the tiny pin hole leaks.

If it leaks down use water and a couple drops of soap in a spray bottle to find the leak -- watch for bubbles. You can use the same technique to test the pitot static system. http://blog.bowenaero.com/?s=blood+pressure -- Larry Bowen Larry@BowenAero.com http://BowenAero.com On Wed, Jun 23, 2010 at 3:09 PM, wrote: > Why not pressure test with air? > > > -----Original Message----- > From: japhillipsga@aol.com > To: rv8-list@matronics.com > Sent: Wed, Jun 23, 2010 6:39 am > Subject: RV8-List: Fuel Tanks Testing > > 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?
