## Description

Camco FEMALE QUICK CONNECT x ACME PROPANE HOSE. Hook up a quick connect grill valve to a 5 or 20 lb. propane cylinder. Designed to be used only with low pressure gas appliances such as the 5500 grill (Coast #57607). 6 feet regulator hose with shut-off valve.

Review: My Onan generator is located in the lower section of the motor home. And the orientation of the air filter system makes for a rather difficult change-out. The Onan filter is of the proper design so that it can be set in place with minimal added effort. Other general-purpose filters would not fit as well.
Review: Fit like a glove

## Questions & Answers

**Q: Should I oil the out foam section**
A: No need to oil the filter

**Q: Will this fit onan 5500?**
A: I would honestly say, take out your old filter(if it's accessible) and look at the numbers.  This is honestly what it did and I bought the same one that was on there.  Sorry couldn't be more helpful:-)

**Q: can this fit the onan marquis 5000 ?**
A: You will need to take a picture of the data plate located on the generator and do a search, such as:  Filters for Onan Marquis 5000 model number XXXXXXXXXXX.  Very easy to find the correct filter.

**Q: Does this fit 4000 Emerald plus?**
A: Fits models around 86 to 9u
