BX 2370 stops

[ottobond007]

I have a BX 2370 after about 20min of run time it stops. if you let it sit for 20min then it will start. If you keep the tank full then no issues, fuel pump ?

Floating debris inside the fuel tank will cause fuel starvation. Debris is further away from the outlet port when the tank is fuel. The lower the fuel level the easier it is for the fuel pump suction to draw the floaters down and start blocking the outlet port. Clean the tank, consider a tank inlet screen to catch junk during refilling and change the rear filter or do both to match replacement time.

yup, Lug66 said it best !
one test though... unscrew fuel cap and run...a really,really long shot is the cap's not venting, forms a partial vacuum, stops fuel flow. Unlikely but easy to test.

With the key in the on position - do you hear the ticking noise of the fuel pump?

IF so - then you have the problem the others have said.

IF there is NO ticking of the fuel pump, the tractor is running on gravity flow, once the tank is lower in diesel the flow is reduced.

Yes I tried that and did clean the tank to no luck.

Yes I do hear the pump running, just thought maybe it doesn't have enough pressure.

The pump diaphragm might become defective. Replace the pump, it isn't that expensive.

The pressure on that pump ..... is very small, like 3 psi.

As mentioned - floating debris, best way to "find" this is - get under, pinch fuel line before first filter - pull filter and allow to flow into a clear container. The flow should remain constant - any slow down will show a restriction in the tank.

remove fuel line at injector pump, place in container, turn key on....tick,tick,tick...fuek should flow into container.
if not, maybe 'gelled' due to cold ?
