I think I need to replace my fuel pump - the truck stalls when it's hot (after about 30 minutes of driving). I have searched this forum and find different answers for the right fuel pump model for a 1967 305e V6.

Some people suggest a Carter M3955, while others suggest the Precision M20021 from O'Reilly's. They look similar to each other, but neither comes up in a search for the 1967 305e engine. They look similar to the one that is in the truck, but the pump lever is straight on those units, whereas mine has a curve to it, as you can see in the attached picture.

O'Reilly's suggested a Precision M16105 (shown as correct for a 1968 305e), which is like a Carter M4503, and has a little short, curved pump lever that would not seem to touch anything whatsoever in the engine block on my 305, so I cannot see that being the right pump.

I seem to recall a thread about this very thing a while back, but I cannot seem to find it.

Can some wiser soul shed some light on my search? Do I use a straight-arm pump lever like the Precision M20021 (from a 1966) or do I need a pump with the curved arm that seems to be unobtanium as far as I can see?
