Autopulse Fuel Pump on Chevy 216

[Pete Ashby]

I ran a a modern electric SU pump on my C15A for years I converted the truck to 12 volt but I believe you can get 6volt pumps if you look on the web Owen.

Regarding location I located it on the inside of the chassis rail under the cab in the main fuel line to the mechanical pump when switched on the electric pump will push fuel through the mechanical pump into the carb when switched off the mechanical pump sucks through the electric pump if you draw the layout out with the spring loaded inlet and outlet valves you will see how this works.

I would be wary of a 70 year old auto pulse pump use a modern one that will be compatible with modern fuel. I found my pump invaluable for priming from cold and for hot starting when vapour lock can be an issue it could also be flicked on while on the road when climbing hills at low speed to give a bit of a boost to the manual pump. I used the location of blackout toggle switch on the dash board so everything looked correct.
