Am I missing something?

Hi Bobcat guru's,

I've got a Bobcat 863 that I'm replacing some leaking O rings on, however in looking around I found what looks like a broken off pipe. Looks like it's situated on top of the fuel tank, just inboard off the fuel return line.
The Bobcat is currently bogging down hard under heavy engine load but still runs, does smoke a bit though.
I was looking through the right side inspection plate trying to find the fuel pick up line when I saw this other fitting.
Any ideas what it might be, and am I in the right area to find this fuel pick up?

Cheers all

I think that's the connector for the fuel gauge.

Awesome, thanks mate. Part ordered

Its not uncommon on the 63 series for the fuel pickup tube to deteriorate. Another thing that will cause it to fall on its face is the main drive belt slipping. I have a 763G and its been pretty good.

I was looking at it this morning and was wondering if I could relocate the fuel pick up entry to just above the drain plug as this is easy to get to, allowing for quick cleans of the filter on the end of the pick up tube?

Edit- After thinking about it, grommet wouldn't seal well enough to stop fuel pushing out due to weight is fuel in tank

I went through the "fuel pickup" thing on an 863G not that long ago. I found it impossible to reach the fitting on top of the tank. My understanding is access is gained by removing the engine. You've got to be kidding me. We fought the problem for six months or so and it came back two or three times. The last time it happened I tried a work around. I removed the fuel filler cap/neck from the hose leading into the tank. Inserted a length of 3/8" copper tubing down the hose so it nearly reaches the bottom of the tank. Put a 90 on the top end and brought it out the breather vent fitting on the filler neck. Attached a length of rubber fuel line to that leading to an electric fuel pump in the engine compartment. Worked like a charm. Has been probably a year or more now with no problems.

I just finished installing a reman engine (Kubota) in another machine and it has much more room to access the fittings on the tank. The Deutz in the 863 was just too tight. I could barely get a fingertip to the line but couldn't do anything with it.

Mine has the Kubota and while not a breeze to do it is doable. Have never worked on one with the Duetz.

This is a good work around, might try this.
The electric fuel pump was to assist the mechanical pump on the Deutz? How did you go about wiring it in.... off a constant hot wire in the engine bay or down to battery and up to a switch?
Cheers

Just tied it to the fuel shut off solenoid. Key is on, shut off solenoid is on, pump is on. Simple.

In fact, I put a pump on the Kubota engine I just installed on another machine. I never cared for Bobcat's idea of the primer bulb for the fuel system. I put the electric pump on the Deutz engine some years back. It just makes things so much easier.
