Kubota u15 fuel starvation

[raggy]

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

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!

any banjos in the fuel lines on these @Mick-the-fitter ??? could be our old friends the banjo gauze filters blocked?

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!

Not sure on that set up but the banjo bolt on the pump looks big enough
