149-2513 Fuel Filter 10 Micron for Onan QD Generator HDKAH HDKAK
This is the fuel filter that hangs under the Onan Quiet Diesel generator in an RV, on the HDCAA, HDKAH, HDKAK, HDKBA, HDKCA and HDKCB models. It is a box-style metal filter that stops 98% of the abrasives in diesel above 10 micron, and when it loads up the generator shows it as a hard start, a surge under load or a shutdown at the worst moment. It replaces 149-2513 along with BF-806, FF236, 33063, PF-888, P50033 and 25010487.

❓ FAQ
Often it is. A loaded filter starves the injection pump under demand, which shows up as long cranking and a surge when the air conditioner or a microwave loads the generator. Change the filter first; if the symptoms stay, look at the fuel pump and the lines.
Change it with the oil and the air filter rather than waiting for the hour meter to hit its interval. A generator that sits over a winter can load its filter with condensation and debris before it has run many hours, and the filter is the least expensive part in that chain.
Yes. 10 micron is the rating this generator is specified for, and the media is high-flow so restriction stays low. Going to a finer filter is where people run into fuel-pressure faults, not staying at 10.
It fits the Quiet Diesel models listed here: HDCAA, HDCAB, HDKAH, HDKAJ, HDKAK, HDKBA, HDKCA and HDKCB. Check the model plate on your own unit against that list before ordering, since Onan also builds models outside this range.
They are the reference numbers this filter is sold under, from Baldwin, Fleetguard, Wix, Purolator, Luber-Finer, Caterpillar and GM among others. If the number on your old filter is in that list, this is the part.

Description
Product Overview
Onan mounts the 149-2513 filter under the generator, on the pressure side, ahead of the injection pump. It is a box-style metal filter rated at 10 micron with 98% efficiency, it is the part that decides whether grit reaches the pump and injectors. On an RV that sits between trips the filter can load up before the hour meter suggests a change, so hard starting and a surge under load are the first signs to act on. It replaces the cross numbers BF-806, FF236, 33063, 3063, PF-888, P50033 and 25010487, fits the Quiet Diesel models HDCAA, HDKAH, HDKAJ, HDKAK, HDKBA, HDKCA and HDKCB.
