1971 and 1977 Ford 302 Fuel Pumps Are They Different?

I had posted earlier w/ a fuel problem that turned out to be a bad fuel pump.

I thought it was corrected when I replaced the defective pump but the other seems to have a low flow rate and I am wondering if I have the correct pump.

My car is a 1971 w/ 302 motor and was wondering if I was given a 1977 fuel pump as they look alike.

I am not sure of this yet but does anyone know if the pumps for a 1977 and 1971 are different.

If so what are the differences?

the bolt line ups and gasket profile are the same but I am wondering if the lever and its bend might be different on the pumps in some way?

Any help would be well appriciated as this is driving me nuts ( and its a short drive)

i believe the pumps from 1974 to 1978 are differnt from 19641/2 to 1973

Went to Summit and pulled up a fuel pump for a 71 and a 77 they are both the same. Here is a link to check it out. Do you know what the motor came out of? Maybe that matters, but when you buy motor parts you will need to buy for whatever motor you have not the car. Hope this helps
