fuel pump selection

[kylep]

I got a 454 in my truck and the fuel pump is going bad. I got a new one and the thing is about centimeter longer where the air hose on the bottom hooks up.

My question is with this new one and the engine mount and the hoses there is no way it is going to fit. I am attaching a picture of the one i know will fit but i am not sure if it is the best one for my truck.

Mine is a lot longer than the one picture but has all the same hookups and i think it would work.
