Hi, I have a Kubota u15 2007, i have had the tank off and cleaned, also all fuel filters, run well for a couple of months but now has a fuel starvation problem.
I did fit a new fuel pump a year ago, when ignition turned on you can hear fuel pump ticking, cannot see any leakage but used almost full tank in 4 hours which is strange. Set off yesterday running rough, then ok for a couple of hours, running rough now. Any suggestions what to check next. Raggy

It’s what I do!
1. Could be the pump is fitted the wrong way round! 2. It’s running by gravity until the weight of fuel gets less the it starts messing around. 3 the filter top is blocked in the 90deg fitting!

If an electric pump I can't see any way that it would let the fuel past via gravity? Not had one apart mind.

No you are right I was giving some examples from experience, I have had an electric pump get crap in it and the one way valve gets stuck open, which when it ticks away on a full tank it’s basically running by gravity supply but making all the right noises!
