This thread is almost 8 years old, but while searching for a Fuel Pump for my Farm Tractor, this subject popped up, on a site that co-incidently, I'm a member of.
I'm still in the process of researching but it seems like this is the correct Part Number for a Fuel Pump for a GM 2-53 Detroit Diesel.
I have a 2-53 Detroit in my original '59 John Deere 435.
