first thing, dirtiest job:

electric fuel pump install
replace steel lines (http://www.americanpartsdepot.com/fueltank.htm)

https://drive.google.com/open?id=1p8RuceTcTN2iTebQEJn6d5wpm0ZIeCaa

clamp for fuel pump was a little too large so i cut some rubber mat to snug it up.
added a 2.75 inch insulated clamp for fuel filter

Thanks for the pictures.  I'm going through the same project right now with a different kit.  It will be interesting to see how the cars compare versus carb.

Did you replace the steel fuel lines all the way forward of the fuel pump?  Thanks.

. Be sure and seal the cap screws with RTV on the adapter plate or you will have a vacuum leak learned the hard way :banghead:
