97 F350 7.3 PS
I have a '97 late production F350 7.3 PS. It will start and run fine if I use it daily. If not then a 1/2 second squirt of ether and it will start and run fine for the day. If it sits for more than a couple days between starts, the ether is the only way I can get it started. My mechanic mentioned something about a fuel line check valve located somewhere near the filter. His research found this part to be obsolete by Ford and the only source he could find was International, (400 bucks +) and even then he wasn't sure this would be the fix. Any ideas?
