A couple of times previously, I posted a DIY parts list for the Champion 3100 Extended Run kit. After again reviewing the video and getting messages from others, an update to the parts list and screen shots is order.
The main 2 changes are:
1) Decided against the Koeler kit and went with a Honda OEM fuel pump and
2) Video's PCV tube shows a miniature check valve, not an automobile PCV valve.
Both new parts are sourceable at amazon. Total price is now about $74 (up from$55). Tank and Tank Hose if you need them are $87.
Attached here are the two newer, Version 2 PDF files with the parts changed.
File "Champion 3100 Extended Fuel DIY finalv2 materials.PDF" is the correct parts list. Everything sourced from Amazon.
File "Champion 3100 Extended Fuel DIY finalv2 screens.PDF" has a collection of screen captures from the video showing where and how each part is used. The screens are in order from the video left to right.
