Ok yesterday I asked about fuel pumps put the new one in, work great for about 50 miles then started starving for fuel again. More throttle dies harder. Can go about 25 mph , sharp turning makes it die also. Stopped for 1.5 hours started and ran good again. Any ideas

There was one people were talking about that was set for too low a pressure. Thinking that may be it. But not sure.

Yeah when we see 43psi it’s time for a new pump . Definitely needs to be set to 52 to 55psi.

Is maybe the new pump faltering when it gets warmed up? You said it did ok after cooling off. Did you have to up the fuse size for the new pump? Was the fuel tank clean when you replaced pump?

I didn’t have to up the fuse. It loses power after riding on rough trails it will only go about 22 mph before missing. It will also die more if I turn sharp either direction.

The tank is perfectly clean.

I was in the north woods with no cell signal so it took me a while to get back to any one. I just ordered a new fuel pump regulator. Thank you all for the info, I will find out in a few days

The other half of fuel issues is air. Mine died on the trail this winter and after changing the fuel filter and pump, pressure testing, pulling and cleaning each injector, I finally checked the codes and they pointed to the t- map sensor. Ordered a new one, plugged it in and it fired right up.

When it happens try loosening the fuel cap and see if it runs better. If a breather is clogged it can starve the engine of fuel and can act like that.

That’s a good idea.
