Fuel Filter Part Replacement

2006 Fleetwood Expedition 37u - Freightliner XC - Cat C7 Diesel Pusher

Primary fuel filter part number is P/N ABP/N122-R50418.

I have a new filter on the way, but I can't for the life of me find the clear plastic bowl that screws on the bottom with release valve. Anyone know where I can get a replacement? Old one looks a little rough.

Thanks in advance!

The filter you have coming , may not require it .

Many suppliers have done away with the plastic bowl and gone to pet cock fittings on a steel housing .

EDIT : Part name is " water ( or sediment ) collection bowl "

Thanks everyone!! Have the Racor bowl on the way. I like having some visual feedback so went that way. Hopefully everything goes together ok.

Received my fuel filter and bowl kit.

Filter Part Number 03-43976-000 and bowl kit RK 30051

Unfortunately they don't seem to be a match. The filter looks like it will fit my existing spot, but the bowl kit doesn't thread onto the new filter. Filter is about 4.25" outside diameter.

Any advice? Feel like this should be easier for me than it is. 😕 Thanks!

Call Freightliner parts in Gaffney, SC and give them the last six digits of your VIN number and they will be able to tell you the fuel bowl and filter part number combination that originally came with your chassis.
