Question Fuel Pump Orings 2004

Does anyone know the correct orings that go inside of the plastic pump housing for the fuel return and pressure line going to fuel rail? Both of mine are leaking after sitting for an extended period of time. Am looking for part numbers so I can replace both. Already have pump disassembled. Turns out that's the easy part. Thanks.

The only thing I can suggest is go to a local hydraulic supply, they usually have every size known to man... take your old ones in to match up as best as possible.

yes the return line fuel fitting is removable. Just cut 6 pieces of shim stock or old feeler guage into strips about .5 inch long and just a little narrower than the width of the retaining fingers. Gently pry back plastic retainer finger and insert shim stock/feeler guage. after all fingers are held back push fitting stem down and out of housing. First note what direction the fitting is facing for reassembly.
