HIPA GX390 188F Generator Dual fuel carburetor LPG CNG conversion kit 4.5-5.5KW manual choke

This is a great piece of equipment to turn your single fuel into a dual/tri fuel generator with limited mechanical skills. I have a newer Predator 9000 and as mentioned in other comments I had to make some slight mods and workarounds in order to make it fit but again with limited mechanical skills I did this in an afternoon and it runs great! I would recommend using some RTV silicone gasket maker to secure the seal between the air box and the new carb. Also removing the bracket that secures the propane regulator to the carb gives you more space to connect the air intake hose without having to cut the nipple. I just used zip ties to secure the regulator a cross bar and longer propane hose tubing cut to size with a razor knife in order to connect the regulator to the carb instead of using that short elbow tube provided. You'll need new hose clamps as well to make sure everything stays in place. All of this will make sense once you see it up close. All in all I would say this was a skill level 2/5, very simple but a little time consuming if you have newer model Predator 9000 because of having to make mods vs the older model where it's plug and play and everything fits perfectly.Materials used: 10mm ratchet, 9mm ratchet, RTV silicone gasket maker, small rotary saw, duct tape and/or JB weld, screw driver, zip ties, propane hose tubing, razor knife, hose clamps.

Did exactly it's job. Converted a gasoline engine to TriFuel. Did have to modify air box slightly to get it to fit onto my Champion 6000w/7500w generator. Other than that, highly recommend. Also recommend setting up the propane/natural gas hookup with braided, reinforced piping. I ran the primary tubing through sime larger diameter tubing as well, just for extra protection as I had to run the piping on the outside of the frame. Planning in going back and redoing it to run on the inside of the frame for better protection. Recommend using 3/8" quick connect brass fittings to hookup to propane/nat. gas. Will udate with pictures and video of install process.

Bolted right on and works flawlessly! Much easier than trying to rebuild the original gunked up carb and now added the option to run on propane!! Very happy with purchase. Had to re-use the choke arm attaching bolt from the original carb as this one did not include one... no big deal. No modifications necessary on my 8750 Predator genny.

Worked great on my Powerstroke 6000. Installment was less then 15 minutes with no instructions. Even if I had not taken the carburetor off in the past, which I have , it would have been a quick install on this powerstroke generator, as it was a perfect match and fit. One exception on the fit, the fuel line on the original carb was larger then the jet on this carburetor, but it’s an easy correction with a small section on the fuel line. I ended up replacing the last section, about 4 inches of fuel line that goes into the carburetor jet/ nipple to the fuel filter, with a spare fuel line I had for my other generator. I’m also not a big fan of just running the propane to the nipple of the regulator and securing with a clamp, but I guess it will work. Make sure you have , or buy a spare grill to tank hose for the propane tank that you can dissect. For $35.00 and 15 minutes of your time it’s worth the purchase.

As many have stated this carburetor is a fantastic item and is actually cheaper than replacing a clogged original carb, plus you get the added advantage of duel fuel use. Win win! There is a slight catch 22 here though if you happen to have one of the newer Predator 8750s like I do. Evidently Predator changed the location of the air intake hose on the 8750 to the back of the air box. Again, as stated the carburetor is a perfect fit but it will require some modifications to the air filter housing. My workaround was to cut the problem air intake “nipple” off the back and relocate it to the side of the box. It is tapered (one end smaller than the other) so I drilled the hole on the side of the housing just large enough to push the small section through from the inside of the air box to the outside. I actually used a heat gun to heat up the area around the hole to make it “pliable” enough to force the nipple through and snug up tight. I also had to use my Drimel tool to shave off a little extra plastic from the back of the housing where it hits the new carburetor. I used JB Weld to plug the hole where the original nipple was.Anyone with just basic handy man skills can accomplish this and there are several YouTube videos that really helped me. I would have probably never attempted the work around had I not seen some of those videos.

The media could not be loaded. Installed on a predator 9000 purchased in summer of 2023. This model has the metal airbox and there was zero interference in installation. Was able to run two 1875W hairdryers simultaneously without issue and only the expected draw on the generator. I used 12’ x 3/8 ID airline hooked directly to the carb with a 3/8 barb x 1/2 NPT adapter connected to 1/2 NPT x 1/2 quick connect. Works awesome!

Very slick and a much better conversion than the more expensive ones. It's a full replacement for the carburetor and the choke lever. There are no instructions! But I got it installed in about ten minutes with a bit of thoughtful tinkering. Or you could take it to your local lawn mower repair guy - he replaces carburetors all the day long. You need to attach a propane hose and regulator to attach to a propane tank - I scavenged one from an old barbecue. Attached a fresh tank of propane and the generator fired right up. Propane much cheaper than gasoline(which you can still use in a pinch - it's a dual fuel carburetor) - and propane burns much cleaner than gasoline - better for your generator and for the environment!There are wires coming out the bottom that I suspect is for electric start versions - I plugged them together and stowed them and the thing works fine.
