Mechanical Fuel Pump Swap question

[phlegm]

So I am still getting junk in my fuel filter so I ordered lines and a fuel pump. I finally figured out how to change the pump but not sure I got the pin in the right spot. Here is what happened.

I put the plate and plate gasket on with the little screws, I had the rod held up in the block using one of the bolts through the front of the housing. Once I got the pump in place I screwed down the remaining bolt till it was attached on one side but snugged. Then I Pulled the bolt out of the front of the housing and got it in place. This is where things went a little off the rails. in trying to get everything lined up the pump moved out a little bit (about a quarter inch)... after wrestling around to get everything lined up etc.. I finally got everything snugged down. My question is when the pump moved out the quarter inch was that enough for the rod to slide into the wrong place? Is there a way I can tell? Or do I just wait till I try to crank it and when I am not getting gas that's when I know I have to redo the install??

Thanks all
