I Just cleaned out the pre filter on the ole 92 cummins. i noticed that the o-ring on the housing is all dry rotted. Looked for one @ the local napa. and walmart, figured i could get an o-ring off an oil filter to work but no luck.....anyone know were i can get this? I asked the dealer about it and he said there was no such part. I belive i am correct but correct me if i am wrong, the "Pre-Filter" is on the bottom of the "Fuel heater" wich acording to the dealer there is no "fuel Heater or Pre-Filter" Anyway i have had it in my hand and need an o-ring for it. any help would be apriciated.

 

Cummins has them - I believe they should be the same as on the p-pump Cummins but Im not 100% sure
