I have a 2017 Polaris 450 ho. It idles fine and starts fine. But when I press the throttle the engine light comes on in the engine bogs down. I do use seafoam in my gas no more than 3 ounces at a time I change my oil often air filters clean. Any suggestions or ideas thanks in advance.

When you open the throttle you giving it air - the fuel system is responsible for adding the proper amount of fuel to the air to support combustion - if it's bogging, it's because it's not getting fuel - check the fuel pressure, the fuel pump is probably bad - happens frequently in vehicles running alcohol blended fuel and especially in vehicles where the fuel is run low in the tank - the fuel pump is cooled by the fuel and if the fuel falls below the pump, it will overheat and burn up

Seems that Polaris has an issue with their OEM fuel pumps. Not sure why it's not getting addressed. Starting to see A LOT of complaints about this issue.

To the OP: Quantum fuel systems....

I just had to replace the fuel pump in my Merc Grand Marquis @ 40,000 miles - got 200,000 on the F150 with no issue, but I use non-ethanol fuel in the truck and it is driven every day - the wife doesn't pay attention to what she puts into the Merc and it takes her two months to use a tank of fuel - I've tried to get her to put non-ethanol in when she get's gas, but she says it's a pain to find it and she just wants gas - in addition, I've tried to get her to just put in 5 gallons at a time - she only uses it to go to the bank, grocery store and her brother's place (all within about 10 blocks of our house) - since I gave her a BP card and I'm paying for the gas, she always fills up so she doesn't have to stop so often, bur I guess a $120 fuel pump and $350 installation is not bad - the car is 15 years old and nothing runs for free - it needs maintenance every so often :unsure:
