Small block Fuel pumps??

[ck5566]

Is the only difference's in fuel pumps being the bottom inlet & outlet lines Orientation setups in which way they are pointing & is the threaded outlet all the same size. I am having a tuff time in finding a line setup that will work with my 1989 305 ci eng. from a Pont. Firebird. Most to all Catalogs only go up to 87/88 for trucks not cars. I know I am going to have to do some modification to the line closest to the carb ( its a Holley) thats a given there. any help or direction would be great, thanks.

My truck is a 68 C10 lwb coils all around
