I had an interesting chat the other day with a gentleman by the name of Brett at Aeromotive[913-647-7300,Missouri].
I had a question about my 11101 pump I bought used from a board member here.
Something was "tinking" inside the pump when you held it in your hand and rotated it end for end.
Hmm?Maybe a loose internal H/P bypass?
During the course of my conversation with Brett,I found out that Aeromotive had problems with the magnet structure and the armature windings when they were exposed to alchohol on a regular basis.
That's something that I always wondered about with most injectors and pumps,fuel lines,etc.
Seems what was happening with the Aeromotives was the epoxy that held the magnets in place would break down and the varnish would come off of the wire on the armature windings.
Of course the pumps would then stop working like they used to and guys would get P.O.'d and get another brand of pump.
Well,I can tell you after talking with Brett that he told me for $98 American they will rebuild my pump with new magnets and armature.
The magnets are now retained mechanically[crimped in a metal frame I believe],and the armature has more windings with better varnish on them to withstand the alchohol.
I was told the rebuilt pump would put out 100 GPH at 70 PSI[the old charts show 475 LBS/HR].
100 GPH translates to 610 LBS/HR~.
Quite an improvement if the # I was told is accurate[I guess I could get it checked afterwards].
The 475# was reading off of the 13.5 volt line,and I'm assuming the new quoted figure would be at 13.5 volts as well[no voltage level was stated or implied during the converstaion I had.].
Maybe that'll clear up some issues for some of you guys.
Hope it helps a bit.....later.
