I agree with Josh's suggestions. However I had a Carter rotary fuel pump which stopped pumping. Seems that the vane just stopped turning which I was told had happened to others running this pump. I replaced it with electric 6 Volt piston pump from Airtex Products which produces 2.5-4 PSI. Part # isE8902. Additionally, I would also recommend that you block off all water to the intake manifold. I don't drive my Cord in the winter so I don't need heat to the carb. In doing it don't overlook the small hole in the bottom surface of the manifold. You can tap it and install plug.

Hi Mike,
I was running a Carter electric pump for a number of years and it quit on me. I talked to others and found that they had the same problem. Seems that the rotary part of the pump would get gummed up or some thing and stop rotating. It was recommended that I use a 6 volt piston pump (Part #E8902) made by Airtex Products. It puts out 2.5-4.0 PSI. My local parts store couldn't get it for me so I order it by going to their web site. It really puts out the fuel.

Hi Mike,
I'm not sure what you want to know. The pump I had been running was a 6 volt Carter rotary pump. When it quit working I started asking around. I found out that others had problems with them too. They seem to think that the rotary got gummed up and stopped turning. They had gone to the Airtex Products pump and were quite happy with it. It really puts out the fuel. Hope this answer your questions?

The Airtex pump, and all the identical others sold under different brand names, is a diaphragm pump. Check Tech Talk in the Newsletter you should be getting any day now.

And I would be careful about the dry intake manifold. After years of pondering I closed off the hoses between the thermostat housings and the intake manifold, as well as the hose from the manifold to the water pump. And the little drain hole that Tom mentions. My engine temp does appear to have dropped an average of about 10 degrees. That's good. But with the dash temp gauge at 160 after a long run last year, I used an infra-red gun to check temps. All parts of the cylinder heads and the radiator top tank were in the 150s to 160s. That's good too. But the thermostat housings (both) registered over 250 degrees! Don't know what's going on in there, but something doesn't like the dead end created when all the outlets are blocked. Remember that in stock form the water is always moving -- either thru the manifold or thru the radiator pipes. Opinions solicited.

Josh,
I was told that it was a piston pump but looking at their info on it, it doesn't say that it is. I email them that question and will let all know when I find out. I like their E8902 as it's pressure is 2.5-4.0 PSI while their pump E8011 is 5.0=8.0 PSI, which is way too high.
