How do I Modify mark 20 to 25 fuel pump?

[Chris696]

Chinewalker mentioned it's easy to change the 2 line to 1 line fuel pump from a MK25. What exactly are the parts needed? Can I just use the pump and lines/connector from the MK25 and bolt them to the 20? Just need to know ALL the parts I'd need to do that, and how to do it. Thanks

After no reply here, I subscribed to fiberglassics.com and after 1 day I recieved a post to check out http://www.aomci.org/askamember/index.html They had some info there that helped me. For those checking themself, try these other forums as well. You will get a reply!! Found out MK25 will work with my motor. Attached some pix. of what and where it goes. Hope this can help someone else.
