Oil & Fuel 3400 fuel leak

[bigballer]

tonight after i changed out the hydraulic inlet hose i ran the tractor for a few minutes and turned some manure, when i put it away i noticed fuel dripping at the bottom of the pump assembly. there are 2 hoses there one coming in from the filter bowl and another going out to the injector pump. i'm thinking one of them is leaking but when i cleaned it up and ran it some more i didn't see any fresh fuel surfacing around the connections. odd that it was dripping noticably then just stopped. i'll keep an eye on it..

Check the black plastic housing the hoses and bowl are connected to for cracks.

I had a l3400 at one time and I think I had something like this happen. But it was with when I changed the fuel filter the housing is not for a better word sort of finicky. Has to be put put together sort of delicately?? Other than that it was a Great tractor ended up trading it on a L4400

Sounds like that dang Murphy guy. Fix one thing and another fails.

Hope it was a fluke.

i figured it out, it's the line between the fuel pump and the injection pump. i tried to tighten the clip on the connection but didn't help much, i guess the line is hardend or cracked. i'll be ordering a replacement line and will probably just swap out all the fuel lines while i'm at it.

in case curious, i've attached a picture of the part - it's 120/130
