A s/n would help.
Is this what you have or should have.....
OM, yes that is the set up, ser # 98J415 i have the same photos in the books but the only drain line on this machine is under the acc housing to drain the transfer pump should the seal fail, i thought since there were no other external drain lines the filter housing might have a internal port that shares the same drain as the transfer pump,that may be plugged up in the filter head. before i take it apart to see for myself i was hoping someone had already come across this issue. thanks for the reply OM, i know in reading past post your not all that fond of the D333 engines and since this is my first time with one i will hold judgement on them until i spend a few days discing the hay fields with it, i've spent a lot of years on my 9U working ground so hopefully this D5SA will be a bit of an upgrade and the 9U will fall into a backup position.
There are a couple of versions of the fuel filter on the D333's, some had an angle valve on top of the filter housing with drain line connected to the valve itself?
