I bought an Interstate 51R 500 CCA battery in 2001 or 2011 and am just now deciding to replace it (after I add some distilled water and try charging it up again! Your Experience may vary, but since you asked I decided to share my experience. I also own a B7800 Kubota.

Yes and it works (apparently - clicks with the switch, etc.) and the mechanic that picked up the tractor checked that when he arrived.

They replaced the mechanical fuel pump and gasket. I have the part they claim was my old one. They claim the diaphragm (in the pump) has a leak in it because there was gasoline in with the diesel fuel. They charge $89/hour for 4.5 hours of labor.

Well, for nearly $700 I have a new fuel pump and should get the tractor back Tuesday. 4.5 hours of labor to change a pump that was held in place by two nuts and two hose clamps! What a racket!

UPDATE: Just paid close to Seven Hundred Dollars to a Kubota Dealer to replace the fuel pump! Sixty Dollars in transport fees and 4.5 Hours of Labor at $89/hr! The mechanic said "You had gas in your fuel tank and it destroyed the fuel pump. Makes NO SENSE to me - if the pump did not work...

Thank you for the links. The dealer came and took the tractor today. The mechanic seemed to think he'd replace the mechanical fuel pump first (he heard the solenoid click - but allowed he might need to replace that as well). I guess I expected more of a firm diagnoses s opposed to suggesting...

I appreciated this thread BUT, I have NO IDEA where the Fuel Pump is located or where this Solenoid is located. Is there a diagram I might look to?

"...a restriction in the fuel line..." When I installed the new fuel filter, fuel poured out as soon as I hit that little valve up inside the fuel filter assembly. As well, fuel ran out of the filter assembly unless I clamped the small center hose coming in from the side (upper, front) of...

OK, the new fuel filter and gaskets arrived and was installed. Also had added anti-Algae chemical as suggested. This did NOT solve the problem. Ran for 15 min or so, and then slowed down and died. Waited 20 minutes or so and started it up and drove it up the hill and into the barn. Anybody...

"you have pressure in the tank (blocked vent)" I have removed the Tank Filler Cap - so how is there "pressure" (other than atmospheric, of course) in the tank? One thing I noticed was that the 'innards*' of that cap are not secure and have fallen out a couple of times during this filter change...

"a little check valve" I found it - after a while. For reasons I do not unnerstan, once I removed the bowl and filter, fuel ran consistently from inside the top of the fuel filter. I pinched off the left tube (it seemed most likely to be connected to the fuel tank) but that did not stop...

Thank you all. OK, some suggestions t check out. I had been hesitant about unscrewing the fuel filter bowl for fear all the fuel in the tank would rush out. I appears there is a mechanism that prevents that (read in another post after searching for Alge!). I will look to the fuel filter and...

My B7800 has begun shutting itself down – and it is NOT a faulty seat switch. I’ll be running it for a while – maybe as much as an hour – possibly only 30 minutes (I have yet to actually time ‘it’). This happened the last two times I’ve had it ‘out’ and working. The engine seems to stall...
