Subject: Europa-List: Fuel system info please
| Getting close to bonding in Cockpit Module, figure should sort out the
game plan for fuel system.|
| Have a few questions. Will be using 914 on XS Monowheel.
| 1) Instead of using the supplied filters, has anyone used 2 Andair
Gasculator/Filters, one for each fuel pump? How many hours flight time, ever
have any clogging or flow problems because of the fine mesh?
Ron:
I took my stance from many hours on a T6 (Harvard) . The tanks hold
fuel from one flight to the next. To establish if water has develloped in
the staorage, we dripped the bottom of the tanks (water drains) - so I
installed the Europa mod water drains, one for each side. To find if water
has develloped in the rest of the system, we dripped the gascolator (Andair
if you wish) which was the last thing to serve the engine, thus catching any
in the lines - so I installed an Andair gascolator in the feed line.
The drains catch the water (mostly) and the gascolator catches water
plus solids in the cup. So the routine is to drip the drains before every
trip and then the gascolator. If you refuel enroute, the chances of the
drains collecting water in a hurry is more remote but the gacolator can be
dripped, or the cup emptied for foreign gas bits.
I am not ready to fly, but that's my plan anyway.

| 2) I am not too keen on having vent on the top of the fuse. Would like to
install on
| the bottom.
| A) What size vent line to use that pokes out the bottom of the fuse?
| B) What shape vent line, Straight with a 45 degree cut off facing into
the wind or
| a bent into the wind vent?
| C) How far below the fuse to let the vent stick out so it is not under
a vacuum?
| D) Has anyone run 2 vents instead of 1?
| E) What is a good location of vent on Mono?
|
| 3) As far as routing the vent lines, you need to go up and if plumbed into
the filler,
| it would act as a siphon break. What is a good way to somehow plumb into
the filler
| neck and get a good seal?
|
| Thanks
