My VMI fuel probes failes when the spacers on the anode slid down and allow=
ed the anode to touch the cathode.  Since the circuit has proven to be unre=
liable.   I got Princeton probes from the inventor/distributor/sales : Todd=
.
ISSUES: The VMI probe is 1/2" diameter as are the existing holes in the two=
 ribs that hold the probe.    The EI probe is 3/4" and will not fit the hol=
es=2C at least not on mine.     The Princeton probe is only 1/4" OD.
The Princeton probe (616-245-7700 x233) is superior to the VMI probe in eve=
ry way=2C except=2C the 1/4" diameter leaves it vulnerable to bending when =
under load such as turbulence=2C coupled with a nearly empty tank.  =20
Thus=2C I reused the old 1/2" outer tube from the VMI as a "carrier tube." =
  I reused the old VMI spacers after drilling out the hole to fit over the =
1/4" Princeton probe and reduced the OD a bit to allow fuel to flow easily =
within the 1/2" tube.    Plus=2C I ran some tests on the spacers and found =
they put off a cloud of contamination in 100LL=2C therefore=2C I coated the=
 spacers with a thin coat of  Hysol (Proseal just as good).
Tricky part!    When making a carrier tube out of the old 1/2" VMI probe=2C=
 the small hole near the bottom of the Princeton probe MUST BE exposed to t=
he fuel unrestricted by being covered by the carrier tube!!  Or you will ge=
t to do it over a 2nd time like me.
Tricky part #2!   Tell Todd at Princeton that you want the 48" probe with o=
nly ONE set point (empty).    He knows why and can explain it to you=2C bas=
ically=2C it reduces the need to fuel/defuel/fuel in the calibration proces=
s.   It is simply just going to give you a linear fuel read.
Shaping of the carrier tube:                   The Princeton probe should s=
tick out several inches past the end of the carrier tube.                 T=
he carrier tube can be shaped to a curvature at the sensor "puck" to allow =
the tube to dip down a bit before it starts back up hill.   With careful us=
e of the dremel=2C you can allow for the carrier tube to have a bit of a co=
llar around the puck terminus and yet still dremel out enough material off =
the bottom of the of the carrier tube to expose the small hole at the botto=
m of the Princeton probe.    Again=2C it's critical that the small hole is =
NOT covered by the al of the carrier tube.
Each Princeton probe is somewhat custom made=2C and I asked that the bendab=
le portion of the Princeton probe be fairly short=2C about 3"=2C to allow t=
he small hole of the Princeton probe to be as low in the tank as possible=
=2C given that the geometry was already dictated by the probe placement ang=
le at the opening as well as the holes in the ribs.
