My old mans went on his 2011 350 at like 15 hours. He bought an aftermarket one for around $80. My '17 450 is still holding strong...

Did that fuel pump come with an ounce of weed inside it ? Damn... that's a pricey pump ! 
On a serious note, I had a '14.5 and 15.5 FE450 and never had an issue. I put new filters inside the tank at 20 hrs after reading of others having issues with the filters clogging up.
Cut your filter in half and check out what the pump gas did to it, I was shocked at how much crap was inside.

I have never had an issue 2013 250sxf and 2016 350sxf but I have only put non ethanol in the tank which I think helps.

I've never had any problems with it.
I had 60h on my 2016 Factory Edition and i have 50h on my regular 2017.
Filter the fuel and there shouldn't be any problems.

California Cycleworks sells them for half the price , back in 2011 and 12 we go through about 3 a season it seemed like 13 and up they had the problem fixed .
We started changing the inline filters every 10 hours, the in tank filter every 30 and ran fuel system cleaner in the bikes all the time and we never had one go bad after that you can get the in tank filters at an auto store for $3 instead of spending 30 through KTM I could post the number later I believe it's for a 78 Yugo

Today's fuel supply is very dirty right out of the pumps. I have found that the use of a "fuel sock" in the bikes fuel tank is the only true way to keep this junk from entering the bikes fuel system and thus damaging the fuel pump. They are cheep and work very well. Also keeping the bikes fuel filters clean helps. Be sure to also use Sta-Bil in your bike fuel.

My buddy's 17.5 450FE bike has been acting funny, starting hard and on occasion not starting at all. I pulled his filter at the races 2 wks ago at the races and it had a ton of crap in it. I popped one of my spares in and it started right up and ran fine the rest of the day. It didn't start for him at a local track this wk and he brought it to the dealer. They're saying that it's his fuel pump and also to stop running race fuel. I've ran straight Renegade SX4 in all 3 of my 450FEs and they've all ran awesome and had never missed a beat ever.

Instead of Sta-Bil, try Star Tron. Much better product. I use it in everything. Non-ethonal fuel is hard to come by around my area.

Did you contact KTM? There was some fuel pumps with kinked lines. Not sure if that caused your failure. But maybe they will replace it for you if that was the case.
I replaced mine at 75-80 hours, the line was slightly linked but never gave me problems.

I called my guy at KTM yesterday they called the dealer and I'm not sure what's going on other than bike is still at the shop and he's not happy that he might miss this weekends race.

When I pull my filter out it was was clean ! But we both run 1/2 and 1/2 race gas , maybe that has to do something with it?

I have a 2016 KTM 450sxf and have had two issues with the fuel pump in less than six months. The first issue was caused by a broken fuel line on the pump, were the fuel tube fits over the plastic part of the pump. Had to buy a new one. The the new fuel pump installed, the second issue was caused by low fuel PSI output. According to the local shop, the fuel pump was pumping 7 psi and it should have been pumping 40 psi. I've never had fuel pump issues with any of my bikes prior to this one. I haven't bought a replacement yet. This is LAME.

My 2017 250sxf just failed at the track today. The pump does not come on and the fi code is 4 long and one short. The bike has 18hrs on it so I am hoping Ktm will help me out. I disconnected the battery to clear the codes and it fired up and just bogged out from lack of fuel . Same code again.?

Bike has 18hrs on it and I purchased a new jug for fuel when I bought this bike . I got the bike in July so it's only 6months old . The fuel pump just stopped priming. I don't think the bag would have helped this.I guess I am headed to the Ktm shop soon.

My pump filter on my 17 Husky 350 split open after 15 hours. Ran like it was under water and had no throttle response. Took it back to the dealer and they had it fixed under warranty in an hour. Before spending $$$ on a new pump, check it out. There are a few vids on youtube showing how to check your pumps.

They are known for fuel pumps failing. Keefer has discussed the issues he's had on several different KTMs.

I bought a new KTM streetbike this year. It was back at the dealer the next day (at 120 miles) getting a new fuel pump. Warranty covered it. Rough start but the bike now has about 13000 miles, flawless otherwise and is a beast

There was a year or 2 around 2015.5- 2016 I think, were some of the fuel pump lines were linked inside the tank.
It’s an easy fix, just not a cheap fix. Takes like 15-20 minutes to change it out. I swapped mine out before it went bad and the line was kinked.(2015.5 250SXF-FE)
