Drain 770 Tank
What’s the easiest way to drain a 770 fuel tank, bearing in mind the outlet is at the top?
Thank-you.
Thank-you.

I used to syphon the fuel out using a large syringe or an airline to start the process.
Re: Drain 770 Tank
How is the 770 tank different from an 880 tank? I was thinking, that my 880 has a fuel shutoff valve in the line to the feed pump. This is a type of valve that can be taken apart by pulling out the valve core once a stop screw is removed. Fuel will then flow out of the valve body. A funnel or a suitable hose may then be used to catch the fuel.

Re: Drain 770 Tank
I could be wrong but the fuel delivery system to the sediment bowl on the 770 is different to that of the 880. There doesn't appear to be a shut-off valve, and the pipe leaving the tank for the engine isn't at the bottom of the tank as per the 880, but is at the top.
Re: Drain 770 Tank
The 880 Implemtic had the pipe fitted to the bottom of the tank and had a shut off valve. All Selectamatic models had the pipe fitted the front top of the tank. The 770 is a Selctamatic. There is no shut off valve in a Selectamatic and there is no 770 Implematic.

My 880 Selectamatic has the fuel pipe leaving the bottom of the tank to a shut-off valve before making its way to the sediment bowl.
Problem solved with the 770. I just disconnected the pipe at the sediment bowl and the diesel flowed out. I thought it was going to be a bigger job than envisaged.
Thanks for the replies.

That's what I find with my 880 Selectamatic too. Perhaps there are differences between delivery regions.tractorfan wrote: ↑Fri Feb 15, 2019 8:28 pmMy 880 Selectamatic has the fuel pipe leaving the bottom of the tank to a shut-off valve before making its way to the sediment bowl.

Re: Drain 770 Tank
What was the design idea to have the fuel outlet at the top of the tank? Was it in a confined space?
