Dan, did you add a new hole or just enlarge the old ones? Any problems with
leakage?

There was not a hole in the top of the cap so I drilled one per the
plans. I am about to go fly and check it out but I do not expect to see
any difference since I did not have any problems before.

I am just guessing here but..... The caps Zenith supplied with my 801 ki
t were vented but not to the top, they have small holes that breath unde
r and outboard of the top surface. After my 801 stained my paint on the
first flight I quickly surveyed the whole situation and bought two more
caps from Zenith. Those I epoxied up the holes to make them non vented s
ince my fuel system incorporated additional venting to the tanks termina
ting under the wings. No siphoning of the fuel out the top of the wings
now and after 270 hours and a few thousand gallons burned not a hint of
venting issues. YMMV.

Ben,
The 701 tanks are not vented, except through the cap.

I figured that. The 801's are not either. Because of the 801 crash in Te
xas a few years ago I purposely ran multiple vents in my fuel system so
as to not repeat that exercise..

Is it common practice to do a fuel flow test before first flight? I had an
article on this somewhere but now I can't find it. Basically, it entailed
filling the tank with fuel, disconnecting the fuel line at the engine, and
measuring the fuel flow. I think the idea was to make sure that the fuel
system would supply fuel at the maximum consumption rate of the engine
(times some reserve factor). This is done with the airframe tilted to
represent max and min incline. This might highlight a venting problem as
well.
