## Questions & Answers

**Q: Is this for a 1996 mh with onan marquis 5000?**
A: Not sure but it fits a 2001 Onan Emerald 4000

**Q: does this cross reference to A054X497?**
A: Not familiar with number you're trying to cross reference to.
When I ordered the Cummins filter to fit my Onan LX790 20hp engine, the box had a label attached referencing to the 1220645 oil filter. The filter I received had different dimensions and the gasket was much narrower than the one's I previously purchased.
Through some research I found that the FRAM PH3614 oil filter was a great substitute.
I've ran my tractor since last November and the oil is still clean and transparent on the dipstick. When I used the Cummins Filters the oil would have been very dirty and dark on the dipstick by now.  I feel the FRAM is a much better choice if it will fit your application.

**Q: Does this fit the Onan E140h motors?**
A: Probably but not absolutely sure

**Q: Will fit wheel horse 416h**
A: IDK but the one you need for that machine is 83-283
