Hello to all, I have an Onan 7.5 genny model 7.5HDKAJ11451D.I've been able to cross reference the oil filter to napa part number but unable to verify the fuel& air filter numbers. Can anyone help, either the onan part number or a napa filter number would be helpfulListed below are filter numbers that I believe to be correct.If you have filter numbers for this in another brand that also would be helpful etc.Thanks for your helpOil filter Onan part# 122-0833 napa gold 1064Air filter onan part# 140-2897Fuel filter onan part# 149 2513

Oil and air filter part numbers are correct. I could not find the fuel filter listed on the web.www.cumminsonanstore.com

Found your filter here. http://www.ebay.com/bhp/onan-generator-fuel-filter That number is shown in this group of filters and is the one I've used in my generator. Changing the oil and fuel filters is a messy job and I've decided to have it done at a service center rather than do it myselfron

Thanks for the confirmations on part numbers.First time servicing it since purchase, as far as mess goes, the DW says that I'm a magnet, now I'll be an oily magnet.

Our last genny was a emerald series, pretty simple to service. From what I've read it appears that the fuel filter is located close to drain plug for the engine oil.Otherwise i'm open to help

Hint. If you don't have line wrenches, get a set. You do not want to round over the fuel line nuts.

Metric or standard flare wrench?

The fuel filter part# for the 8KW is 149-2513. It is no where close to being the same as the 7.5 filter
