If your Engine is in proper tune and the carburetor is adjusted correctly the choke and accelerator pedal is all you should ever need to start in most climates,but In extreme cold a block heater solves that problem.

Gentlemen, I have a G741 1962 and recently I bought a kit a the photo below and what a surprise was missing the elbow nozzle (third one) as it's missing from the photo too. I have a custom made one to make it work but it's not performing good enough

The primer kit should include the following:
Not all of these parts will be required for every installation, as this kit was designed to be used on early G741 trucks with the regulator bracket mounted fuel filter, and on later trucks with the fuel filter in the tank (the supply line for the primer pump is different depending on the filter configuration).

To add to this if you read through the PS - Preventive Maintenance Monthly magazine over at the radio nerds site, there is an article in one of them about the dash primers. It seems they were causing maint problems and for trucks used where the winter temperature did not get below -10 units were instructed to unscrew the T fitting that went to the dash primer pump and insert a metal cap sort of thing and then screw the fitting back on. This blocked the flow of gas to the primer pump keeping fuel from being in the cab and possibly leaking. The cap could be removed later if the truck went to a colder climate.

52 M-42 had a good idea to install a valve in the supply line to the primer pump. I purchased a Weatherhead (Eaton) 6820 brass needle valve for that purpose.
