Pre Serp PAS Help Needed

[wixer]

I've asked this queston before and I'm still struggling for info. I'm going to convert my Pre Serp Griff 500 to PAS, I've got almost all the bits but what would be really helpful, would be some pics or diagrams that show where the PAS pump fits on a pre serp engine. Guillotine kindly sent me some pics of his but as his has aircon, the whole setup is different again. Any info would be gratefully recieved.

Thanks
