HI THERE

the fuel probe in the Lancair 4 is installed from the tip.

there are no serviceable p= arts in the probe=3B it is about ten feet long and is shipped
by truck in a 12 foot box an= d shipping costs about the same as the probe

i have been dealing with an intermittent for about = six months and located the wiring issue an the
head of the probe. could move the wires aroun= d and get good indications... for part of one trip
tried tie wraps=2C tried loose=2C tried= tight=2C tried epoxy. i got good at removing the wing tip

NO GOOD=2C
 =3B =3B =3B =3B =3B = =3B =3B =3B =3B =3B =3B =3B we removed the probe an= d nothing we could do. ordered the twelve foot box shipped from California<= /font>
=
that's more than i want= ed to know about fuel probes.

a sad side note is that the very early Lancair 4 airplanes had the p= robe installed from the wing root and to fix them it is necessary to remove= the wing. that was a bad idea from the get-go
