electric fuel pump for 6 volt v8 flathead positive ground
 

My fuel pump died, bought a new one and still Not pumping. I checked the line and it is not clogged. I'm considering an electric fuel pump. I see summit has a Airtex 6v pump.
My question is will work on a positive ground system? Anyone have any experience with this?
Thanks for your help

I have the Airtex 3 psi model on 2 vehicles and they perform well...I use them for starting after the cars have been sitting for a while.....

I'm not sure if polarity matters on the pump, my guess would be it doesn't. But no reason to not wire it up with the correct polarity, the (+) terminal on the pump would connect to ground and the (-) terminal would connect to power. That should keep the electrons happy. :)

Works perfectly on my '47 6v with (+) terminal on pump connected to ground and (-) to power.

Rock Auto has Airtex for a reasonable price.

I replaced a bad pump on my 50 a couple of months ago for the same reason, it seems that the diaphragm stretches more than OEM or the arm travel is not as well designed on after market pumps. A friend that has worked a lot on flatheads said to add a piece of leather in the cup of the pump arm, said it would improve pump action.

The Airtex pumps do have a life, albeit reasonable. J. Seery is correct. The 6 volt pumps will work on either a positive or negative ground and his explanation of how to wire it is spot on.

Send the pump to charlie ny for a rebuild with an ethanol safe diaphragm. No need to mess with half-assed fixes.

You won't be disappointed with the Airtex. Good little unit !

Which idea are you talking about? A electric pump is all that will work on some applications, a lot of people have installed a electric to assist on hot starts. The leather I mentioned was to test the pump action, not a repair. If the leather makes the pump work the arm is not designed correctly as I stated. Everyone has their own ideas how to make things work.

E8902 is the correct Airtex pump for these Fords.

I have the airtex on my 6 volt positive ground. Works great.

Sadly, my Airtex experience hasn't been as good. Pressure-side fuel leaks around what appears to be a pressed-in female pipe fitting on a new unit. Jack E/NJ

I found rock auto by mistake..their prices are very good for the products they sell and delivery was quick, even down here to NZ.
