fuel overflow

Ginormous · Apr 2, 2012

Hi guys,

How much and when should fuel come out of the overflow tube? I noticed today that I have fuel weeping from my overflow tube. This is the tube that comes off of the second injector. Does this indicate a partially clogged injector?

Good question? I doubt it is a problem injector but on mine the return (what you call an overflow?) goes into the fill neck of the fuel tank. I cant tell you how much is normal it cant be much though jmho.

Is something missing or what is what I am thinking at this point about it. The return on some (mine) goes into the TS system and then to the tank.

I bet his hose rotted off and does not connect back to the tank. G, your lines should connect the injectors back to a nipple in the fuel tank neck to return it to the tank, it will dribble a bit all the time from what i understand.

Hmmm, I didn't know that. Thanks!

Can someone post a picture of the return hose connecting to the fuel tank? There is something on the base/side of the threaded part that the fuel cap screws onto. I thought that the "something" was a pressue relief so it wouldn't form a vacuum in the tank as fuel was used. There's a hole in it... like where you could push a hose in.

The hose on mine is very flexible in the part that comes off the injector, then there's another piece of hose spliced onto it that is very stiff. I tried to shove this stiff hose into the thing on the fuel tank. I got it in, but I don't have any confidence it will stay. I put a ticket in with Hoye to find out if they have the hose/fitting on the fuel tank.

I think there is a little metal nipple that goes into the tank that the rubber line then goes onto. My tractor is 3 hrs from me now so i can look. There wont be a vacuume in the tank because the vent is a slit or space in the neck under the cap and the rubber washer thats there, trust me it vents through the cap, thats why u just wanna snug the cap up and not wrench it down like your tighning a car lug nut!

Here is mine.

Thanks, Winston. Looks different than mine, probably because I don't have the thermostart -- wish I did! I have a small (~1/4") diameter host coming off of the second injector. I'll see what Hoye has for me...

My Tank was getting pressured up and leaking at the Injector Return when it was full or close to full of Fuel. You could actually see the Air Bubbles blowing the fuel out. Didn't like that at all

I done two things first I used a piece of old Vacume line to seal the return and new if I done that there would be no way for the pressure to escape so the Fuel Cap Ghetto rig. was next. It works great. It's off an old ATV or dirt bike gas tank

The Blk. cap on my TS is there just to keep it clean. I Only have to use my TS Rarley and it just takes a secound to add or remove it

you prolly have the plastic tank like me, it is a small plastic barb on the LHS below the thread for the cap. the hose goes from there to the closest injector then from the other side of that inj it goes to the further one. job done, and it only dribbles a tiny bit depending on how hard you are working it.:thumbsup:
