A: No. The R12T is a sealed unit with a non-removable filter you must upgrade to the R12H assembly to use replacement cartridges. This is why the R12H saves you money long-term. Q: How do I install the replacement element? A: 1) Shut off fuel supply. 2) Unscrew the R12H housing. 3) Remove the old element (may require a firm push). 4) Insert the new element. 5) Lubricate the O-rings with clean fuel. 6) Reassemble and fill with fuel before starting. Q: Does this include O-rings? A: Yes. Each filter element ships with the required O-ring gaskets so you can replace the seal at the same time. Q: How many elements come in this package? A: This listing is a single (1-pack) replacement element. Q: How long does one filter element last? A: Replace every 100 hours of operation or annually, whichever comes first (roughly 15,000 km in diesel applications). Replace sooner after any fuel contamination event. Q: Do I have the R12H assembly? A: If your fuel water separator has a detachable aluminum housing with a replaceable internal cartridge, you have the R12H. Need the assembly? Shop here.
