Any recommendations for a 6 volt electric Fuel Pump?

[auburnseeker]

The Hudson is running fine,  but I would like to buy a spare electric Fuel pump for it as someone long ago (assuming when the engine was installed with dual carbs) removed the original mechanical pump and set it up with an electric one.  That is now probably atleast 20 years old and has who knows what kind of crud in it and could fail at any point.  

Thanks for any recommendations.

Airtex. Available at Summit for like $35 and they come in both 6 and 12 volts versions. The original mechanical pump or that old electric pump can pull through it so theres no need for a bypass. Grounds to the frame so you just hook up power which I always put on a seperate switch and make sure its on the ignition so it doesnt run when the car is off. Comes with a bracket and attaches with standard fittings and hose barbs. Also its quiet. I cant even hear it running on my Olds. I put them on all my cars.

Sounds good I'll order one in for a spare.

Be advised, the 6 volt come in two different pressure outputs.  The Airtex E8011 is rated 5-8 psi.  The E8902 is rated 2.5 to 4.5, which is a closer match to the output of many early mechanical fuel pumps.

 

I have a customer who someone put a higher pressure pump in the car and it once jammed the float needle. He doesn't dare use it full time, only for priming. Whereas the original mechanical AC pump on his car is rated at 2-4 psi output, with the E8902 he could run it full time and not have to worry about over-stressing the float & needle. 

 

Plus, anytime you change the fuel pressure, you also change the float level in the carburetor.  For a backup pump, you want the electric pump's pressure to be close to that of the mechanical pump's pressure so that  it doesn't change the float level a lot when you have to switch on the electric pump.

There is a pressure regulator in the system as well already.  But I'll be sure to order the lower pressure pump.
