Fuel Pump question

[jsdoyle]

My fuel pump on my SB350 is leaking oil and gas. So I bought a new one that is suppose to be for a small block 350.

I got it in the other day and noticed that is has a slightly different layout. The one on the truck has a small nipple off the bottom that the line from the tank attaches to (pic 1).

The new one has a different layout. No nipple but two similar openings on the side (pic 2).

I've not swapped one of these out before but it seems pretty straight forward. I've read up on some installs online.

So, I'm hoping first that I didn't actually buy the wrong fuel pump and second if not which hole is the intake and which is the output hole?

I'll have to get me a new fitting to go in the intake side which should be no big deal.

Any advise?

Thanks!
