Tri-Fuel Propane Natural Gas Conversion Predator 3500 Inverter Generator

I have an older Predator 3500, before the CO shut off and fuel indicator on top of tank. The fuel adapter took about 5 minutes to install. I used a clamp on every connection because I'm overly cautious, so I had to buy five for my set up. I used the teflon tape on all the screw on connections. I added a quick disconnect so I could leave the male connector inside the generator and access it through the oil change door when needed. I used a screw on clamp to secure the connector (https://www.amazon.com/dp/B00835H50C?psc=1&ref=ppx_yo2ov_dt_b_product_details). Then added about 3 feet of hose (https://www.amazon.com/dp/B09GM2X3TH?psc=1&ref=ppx_yo2ov_dt_b_product_details) with female quick disconnect (https://www.amazon.com/dp/B00DE8U6AY?psc=1&ref=ppx_yo2ov_dt_b_product_details) and connected the other end to the regulator with clamps on all the connections. I now store the adaptor inside (with the two dust covers the regulator came with still in place) and keep it next to my transfer switch and cable. When the need arises I will simply remove those caps, screw the high pressure regulator into a tank and then use the quick connect. A push of the low pressure regulators primer a half pull of the cord and I'm golden.When running on propane I can't get the generator to produce a constant draw more than about 2800 watts. It may be because propane is less energy dense than gasoline or because the quick connect I used was only 1/4" inside diameter. The nut on the primer/regulator is only one thread in so I'm definitely getting it all the propane I can.Storing propane is so much easier than rotating gasoline so I'm very happy with the kit. I wish it came with a quick connect but American ingenuity (and $50 in parts and clamps) can make this an awesome kit. I searched for a long time to find the parts needed so I put the links in the review. I hope Amazon doesn't remove them because this post should make your life easier!

I have no idea why I was asked to rate it's "stretch", I am sure not going to stretch a gas line.Use it on a Harbor Freight 3500w Predator inverter generator for my travel trailer. Using propane is much easier than gasoline and not having the odor of burning gas is nice. I do have to turn off the AC before using the Microwave, but other than that, very happy with the setup.I wish the kit included a quick disconnect assembly, that is something I plan to purchase and add as not being able to remove the propane hose kit is annoying when moving the generator around and storing it.

easy to install, and runs my predator 3500 on LP and NG just fine.

My 8 month old 3500 generator from HF the carburetor is not where the Youtube shows. it is buried inside and bu the time you figure out from the front and the side to get to it and take the cover off, you can put the plate in but when you put the cover back there is no thread left to start the nut and there is nothing you can do extend it unless to plan to dismount the whole thing since the bolt comes through the engine housing. very frustrating. so much hope...:(.

I tried several different methods of installation. I had to buy some additional parts. The company was good about communicating with me but I had to take the kit off. It wasn't safe even with the additional parts. It would just vibrate loose and start a propane fire.It's best to just buy a generator that is already dual fuel.

Exactly what I needed and simple to install. Could`nt be better.

I could not get my new Predator 3500 to run under load using this fuel conversion kit.I tried every solution that Nash Fuel Systems offered over text, to no avail.
