I am currently replacing the Auto pump housing on one
of my I-Converts....they run 25-30 psi before the
check ball valve releases, per the factory manual...

the purpose of the pump
is only to circulate fluid through the system for
cooling, right? I
suppose we could do some testing. I looked in the
McMaster-Carr catalog
today. They have a gear type pump with Delrin gears
and a 12VDC motor for
about $47.00 I'm not sure how a fuel pump would
work, but this gear pump
would probably work good on ATF. Rated for 13 fl.
oz./min 20 PSI or 63
fl. oz./min @10PSI on 200 CPS fluids. Max temp 200
degF. 1.6 amp draw.

For guys that maybe aren't familiar with
McMaster-Carr, they are a huge
industrial supply house. Probably every
manufacturing plant in the US has
at least one of their big yellow catalogs in the
maintenance or
engineering office. They have a great web site too
http://www.mcmaster.com. I buy lots of MC stuff
from them too. Loopframe
tool box locks, vibration mounts, various hardware,
fateners of all
types. Order online and they ship it fast!

 but what flow rate is the stock pump putting out?
can't be much..
 1 amp, seems like a big draw on the convert's
electrical system...

 Solid state Facet fuel pumps are rated at about
1 amp on a 12
 volt
 system (www.pegasusautoracing.com) for race
cars. The lowest flow
 rate
 15 gal/hr @ 1 psi with a maximum fuel pressure
of 2.4 psi - 4.5
 psi.

of

maybe 6" long,
 3"diameter..if

that would work, i'd

over
 
 it....

 I think I've heard about that bike. He's
using the pump so
 the
generator
 
 
 is in the stock location and he has a stock
looper timing
 chest cover.
 
 
 Interesting idea. Greg, do you know what
kind of pump he is
 using?

 i saw an ambassador vert setup at the ohio
rally which had a
 fabbed
 
 
 
 up tank
and an electric pump. vert tranny, ambo
motor. tank was
 just like
 
 
 
 a
chopper oil tank...
i'd like to put an electric pump on a vert
project i'm
 building
 
 
 
 (pump is
missing from timing cover...) anyone done
this yet?
 
 
 
 
 
i have 2 verts with the lighter flywheel
(one of which is
 the one
 
 
 
 i'm
building above..), i have a spare heavy
flywheel, but
 haven't used
 
 
 
 it..
they say the lightweight flywheel is
unreliable, i haven't
 had a
 
 
 
 problem
yet. but then again i only have maybe
10,000 miles on the
 vert..
 
 
 
 
there is a yahoo group for verts, that
someone may know
 more..
 
 
 
 (mgconvert)
is the group..
