I think they are compression fittings, so try tightening them down a little more.

No, they actually have little o-rings on them called olives. PM type4 because he can get them for a good price.

Contact any diesel repair shop.........Navistar dealer should have them.

You need three seals:
1 EA..... 3/8 ID for the lift pump to filter header line.

2 EA..... 5/16 ID for the filter header to IP line.
