if ya can't find it, post and I'll take a pic
do let me know if it's a 3 cyl or 4 cyl.. COMPLETELY different machines..
if the 3 cyl, i can get a pic of the pump for the independent pto model, on my ford 4600. my level check plug is in a different palce than yours.. but if you find the pump cover.. you will find the plug.
onthe 4 cyl, it's just a plug on the back of the trumpet.. but i can get a pic for you there as well.
post back.
