Hello, I am still sorting out our 1973 914 1.7L. The fuel pump is seized up and I can not find a cross reference for a proper replacement. The pump that failed is a Carter 4K17A. I can not find any information on this pump. I assume the webers need 3 psi fuel delivery to run well. I have found a low pressure Bosch unit at parts geek but hesitate to purchase until I get suggestions from others on this forum.

Any suggestions/recommendations?

Thanks

I have used this one from CB performance."3193 Rotary Fuel Pump"
Matt

that's the way to go

Another great high quality option is the Pierburg 7.21440.51.0

only one to use,seem to remember the CB Performance one is in fact a Carter pump anyway,if you buy as a Carter it's actually cheaper than the CB one,I use a regulator (Holley LP ) and 7.5 amp fuse with mine,mounted on the steering rack it is fairly quiet but still enough to hear when its running.
