 Posted: Wed Jan 26, 2011 4:50 pm Post subject: Who has fuel pipe experiences I can use on Europa- |
 |
|
1/ Europa system with "rubber" hose, I am put off by permeability & 5 yr life,
couple of inches of ptfe to link sight gauge considered if I need to fit any
flex connections.( replace sight gauge tube with single capacitance system in
uk, I am considering flow measurement also)?.
2/ Versatube -6 3/8" aluminium fuel systems seem good but special tools for
flaring, have heard of Swagelock fittings used instead of AN fittings,
would they be approved or fail UK rules.
or -3/ Nylaflow Nylon -6 3/8" tubing used with brass (flareless)Polyflow elbows
and fittings (with tube ferule inserts) (Listed as fuel pipes pge 103 & 105
aircraft spruce USA 2011 catalogue.(I am aware of history with PTFE fuel pipe
static discharge perforations prior to aeroquipe 666 carbon conductive tube, but
seems to be due to tracking to stainless steel sheaves, are you aware of any UK
restriction on use of Nylon )?
For price and durability combination of the above is currently preferred, using
Aeroquipe 666 firewall forward with fire sleeve insulation (as per Europa heat
insulation mod).
Fuel pump Facet 40106 4-6 psi 30 gph, I do not want to install in back of a/c ,I
believe x xxxx has his fuel pumps for 914 forward LAA mod approved, ( less
fuel line and fittings) any thoughts/objections.
The existing Europa fuel tap would be rotated 180 degrees so outlet faces
forward & the pump... probably move selector valve vertical and the LH /RH tank
inlets would come in on the horizontal (Tri Gear so electric flap actuation, &
tunnel is available for pumps and pipes)
Fuel filter..I would prefer to fit a single combined gascolator incorporating a
large capacity filter firewall forward ( rather than two small filters liable to
blockage under seat pans with more joints) I have the Europa mod water drain kit
.pair of drains and would do shortest practical run down and out.
Practical experience and facts more than welcome, would prefer to install for 10
to 15 yr durability, also any available club 37 degree flaring tools? or anyone
prepared to purchase as syndicate, or dies I could copy to use with my brake
line flaring kit...
Regards
Kevin

I have fitted 5/16 aluminium pipe for all my pipe runs except the tank
drains which are in 1/4 and use 2 of the same type of fittings as supplied
with the tri-gear brake kit . I have used AN fittings through out because
they are easy to find and if you have to replace in service again easy to
source.
As my inspector pointed out, the Rotax engine does not burn a lot of fuel
and has 2 carbs so there is not much fuel flow and very small jets in the
carbs so greater chance of a fuel blockage. I have fitted the 2 in line
filters Europa supplied as well as a gasolator with drain .
I would have happily lent you my flaring tool [£68.00 from LAS] but it was
stolen in November along with all my tool and any copper they could find !
Good luck Richard

Kevin,
I have a flaring tool and I'm part way through installing my fuel system at the moment (914 trigear too). It seems easy enough to use, and you are welcome to borrow it if you live locally or can wait long enough for me to finish this bit!
I'm between Milton Keynes and Aylesbury 01296 689165.
Regards
Bill
