The oil capacity will vary depending on the particular model within the GP Series. The specifications for your particular model can be found in your owner’s manual under the “Engine Specifications” section.

Question

Fuel Leaking

I received this generator as an early Christmas gift. Started it once to verify everything worked and it did. A month and a half later I went to start it and before I could, gas started leaking from the carburetor the second I turned the fuel switch on. Why is that?

I get the "don't store with fuel in it" deal, but were talking a month and a half. Fuel was new when I put it in. So now what?

Can this be something else. I have read alot on the internet about this model leaking fuel. Is there some sort of recall on a specific part?

Any help would be greatly appreciated.
Thank You

The fuel bowl works much like your toilit. There is a float with a 'needle' on it, when the bowl fills up with gas the float rises and the needle closes off the fuel flow in the 'seat'. The needle and seat are two machined surfaces with no room for anything else between the mating surfaces but fuel. A small particle can cause the float to 'stick' open and the needle not to close fully. This is what it sounds like has happened to you. You said the fuel was new, was the gas can also? Was it clean? We have seen something as small as a dead spider in the fuel hold open the needle. I suggest you take it to your local Generac dealer and have them inspect the carb.

There are no provision to add an oil filter to the GP series generators. Oil filters also (usually) indicate a oil pump or pressurized lubrication system, the GP series are a splash system like those used on most smaller engines. If you maintain the correct service on this unit there is no need for an oil filter.

The GP5500 model 5939 is different from the model 6110, as the 6110 comes with a 20 foot extension cord. This accessory included with the unit causes the model numbers to differ, but the features on the unit itself are the same.

Question

Is the generator damaged by running it to empty gas in the carburetor?

The manual reccomends running the engine until the gasoline in the carburetor is gone. This causes the generator to run rough for the last minute or two. Does this damage the system?

For our portable units it is recommended to allow them to run dry. Doing so will not damage the engine. Running the unit dry will keep the carburetor from becoming gummed up with stale gasoline if left to sit unused for an extended period of time.

Question

Running an RV from a GP5500

Has anyone run a RV off of a 5500? I am looking to run the camper and it has a 15k Btu air conditioner. It will not run on a 20 A circuit at my house. Needs a 30 A circuit. Please let me know if any of you have run a circuit of more than 20 A but less than about 30 A off of the 120/240 V output on this generator. The spec sheet says that circuit will deliver 28.6 A. Thank you.

The GP5500 portable generator is rated for a continuous output of 5500 watts, with a rated amperage of 22.9 amps at 240 volts. You will want to ensure that all of the items you intend to run will not exceed this rating. Please keep in mind that some campgrounds have strict requirements for noise regarding generators. Unfortunately, because there is no industry standard for testing sound levels on portable generators, we do not currently list a decibel rating for any of our portable generators.

Question

Power Surge Strips

I blew out two power surge strips on another brand of generator. I bought a new Generac GP5500 and also new power surge strips. The instructions that came with the surge strips said not to use them with a generator. Why would this be and is it true of power surge strips in general or is unusual for strips not to be used with portable generators?

It is generally a good idea to use surge protectors for any sensitive or expensive item such as TV’s, computers, or stereo systems, regardless of whether you are running on utility or generator power. However, Generac does not manufacture surge protectors and therefore we are unable to comment as to why the particular surge protector you have purchased states that it is not for use with generators. You will want to contact the surge protector manufacturer to inquire as to why they do not recommend it for such use.

The GP5500 has one 240 volt capable receptacle, the L14-30R. The 120/240 receptacle will put out the voltage that is required by the item or cord plugged in to that receptacle, as long as a properly rated cord is being utilized. The attached diagram will show the outlet location.

Question

Some specific maintance questions for my GP 5500

OK, I like over a million people on the east coast was out of power for several days this last week. My GP 5500 ran flawlessly for the whole time (albeit louder than I'm sure my neighbors like (but what the heck, I had power!)) Anyway, now I want to give it some good PM so it works flawlessly again next time. Here are my questions.
1. When checking the oil, do you screw the cap all the way in to get a reading, or just place it in the hole without screwing?
2. The manual says to check the valve clearance after the first 50 hours... I definitely exceeded that, and now want to do that, but can not find any decent instructions on your site on how to check the valve clearance. I'm pretty good at this kind of stuff with instructions, but don't want to attempt this without them.
3. What is, and where do I find a fuel stabalizer because I see in your answers to other questions that you do not recommend draining the fuel, just adding the stabilizer.
Thanks in advance for your answers.

For the GP5500 when checking the oil, you will want to screw the cap all the way down to obtain a proper reading. Just setting the cap into the opening without screwing it in will give you a false reading and can cause the oil to be overfilled. We do recommend checking valve clearances, however, we don’t have any further instruction other than what is located in the manual. If you are unsure of how to check valve clearance, we recommend having it done by a Generac certified service technician. When preparing the unit for storage, we do recommend a fuel stabilizer if emptying the fuel tank is not feasible, but it is stated in the manual to be sure to empty the fuel tank. If needed, a fuel stabilizer can typically be found at your local hardware or automotive supply store. We also recommend that the unit be started at least once every 30 days and be allowed to run for at least 30 minutes. If this cannot be done and the unit must be stored for more than 30 days, the unit should be prepared for storage per the instructions in the manual under the section titled Long Term Storage.

The type of extension cord described above can typically be purchased at a local hardware store or electrical supply store. You will want to ensure that the rating for the cord is listed for the amperage and distance you are interested in. If you are looking for a cord to utilize with your 30 amp receptacle and you have a minimum distance of 35 feet, you will want a cord that is rated for 30 amps at 35 feet, or 30 amps at 50 feet, etc, depending on your distance requirements.
