I had a fuel pump failure last July on my '16 DL1000 Adv, I posted about it and the response which I am still thinking about by one Stromer was that fuel functions as a COOLANT medium the pump is submerged in. This happened a week after riding for nearly 600 miles on a day in 95F weather and 85mph or faster, plus, I tend to max out on my range per fuel fill. In other words, the fuel pump did not like to operate in hard/hot conditions with not much to COOL it ? Does this make sense to you too ? Or was the failure a one in a 'million' occurrence based on a mechanical failure of the pump assembly and not related to conditions described ?
I am wondering if any of you Stromers out there had any fuel pump failures and what is your story ?
Just to be sure, I am thinking about changing my approach to refueling in hot conditions from now on, do not want to get stranded again with an empty fuel tank. Did not pick up on instrument cluster distance-range left reading in tank being way OFF (related to distance already travelled on that tank of fuel // always zero one of the trip meters when refueling), the morning I left the house to commute to work.

Thank you,
Juergen

The air temperature will have no affect as the pump will run hotter than the air but keeping a higher fuel level will keep the pump cooler.

After fitting a PCFC to my V2 I ran out of fuel 3 times in one day (& still 9.2ks from town)(thanks Brucestrom)

Even though I know it's not good for my pumps I always run my tanks down to the limit when possible, just because I hate stopping.

I currently have 43000ks on the clock with no pump issues but I do expect them in the future.

As far as I can tell the "Distance to empty" display looks at your calculated range since fill up to see how much fuel is left (has been used) and then based on the amount of fuel left and your mileage over the last 10 (or so) km figures how far you could go on the fuel it feels is left.

It also is pessimistic in hot weather (ie you usually will get better mileage (range) than the calculation and is pessimistic in cold weather (ie your mileage is worse than it calculates and you mighty run out of fuel before the range to empty hits 0.

It would be interesting to use my IR thermometer and get some temperature readings from the fuel at differing levels but I hate stopping for fuel so I'm unlikely to stop for the readings.

I remember some fuel pumps used to have foam wrapped around them. It was soaked with fuel and helped to keep it cool I assume.

Haven't seen that lately. :confused:
