Upsidedown fuel pump??

[Bandit67]

Guys on all the video's of fuel pump replacement I've seen, the fuel and vent lines are on the underside. I've a 1986 Custom Deluxe and removed the fuel pump with the gas and vent line on the topside. Now I'm having issues holding the pushrod up, to get the pump lever under the pushrod. I've asked around and the consensus appears to be that I'm trying to install it upside down! Also there's no screw on the block to screw into to hold the pushrod up and the smog pump bracket hole is a blind hole so that's not it either. Any help would be appreciated.
thanks
