L4150DT Algae Nightmare Cannot Bleed Motor

nightowl490 · Apr 15, 2014

Pushing brush, moving downed trees, prepping foot plots, then she coughs and sputters. No fuel in sediment/filter bulb, pulled off tank line at pet cock and an algae turd comes out then gushes fuel. re-attach line, remove filter, some algae goob but not blocking filter. Re-Bled bulb and began bleeding process......... I cannot cannot get it do any more than cough. I have had fuel lines removed/replaced and have bled before but something feels a miss this time. I kept battery from draining and kept up the 10 second bleed process but no luck...... I have posted on this before but am hoping for some new tricks.

Also, by the way, I talked to Ronnie at Tractorsmart (Great Guy) and he no longer offers specialty parts for Bota. Looks like it's on to Messick's? Thought I would update a few things on tractor for the year.

Anyone??

Lift pump supplies fuel to the injection pump; it most likely is air-locked and needs to be bled first. Pull the hoses from it (2) and see if you can pull fuel through it.

Good luck, Fred

If you have algae in your fuel tank you must clean it out completely.
Drain the tank, rinse it with some clean diesel, then re-fill with fresh fuel and add some biocide treatment that will kill any remaining algae.
You might have to change the filter a couple of times before all the gunk is gone.

Update

Couldn't take it anymore, pulled off lines as recommended., had good pressure but lots of bubbles.. Completed bleeding process and whaallaaaa.... Coughed and fired, ran for two hours no worries... never underestimate bleeding process!!
