Fuel return nozzle leak
By: Dadog13 Date: February 28, 2022, 9:39 pm
---------------------------------------------------------
Hi all,
Had my tank off for a while and now on install I have a leak
from the fuel return nozzle (bottom of fuel pump) around the
nozzle base before pipe joint.
It had some slight movement before taking off so hasn’t changed.
Does the fuel system need to be primed and full of fuel before
nozzle makes a seal or is there damage?
Any one else had this problem.

Gidday DD, thinking the forum was dead but not quite. Yes and
no to having that problem. No to the system needing to be primed
to assisting the sealing. Return line is lowish pressure and a
simple barb fitting so shouldnt be a problem to seal, you do
have to be a bit carefull that it is not being kinked when you
seat the tank fully home. Is it spit at join?
Did have an issue a few years back when I had refitted the
supply line, gone for a dyno run, ridden at Phillip Island then
went for a short ride from home only to have that line pop off
and drain the tank while riding and rear tyre sliding around,
just got home as tank emptied. So watch that the supply line is
on fully and that the connector has clicked into place.

Hi Mate, I've had no issues at all with the return line. Its a
bit tight under there so make sure the hose is pressed home
fully and as Graeme says not split. Its low pressure so should
be an easy fix. My problems have been with the pressure supply
side. The high pressure supply side has snap on connectors which
can be a bugger to undo. I butchered the one on the underside of
the tank and had to replace it. The fittings are Yamaha specific
and expensive so be patient with them. Cheers Steve

I had the same problem as Graeme, after having the tank off one
day I replaced it and went out for a ride with no problems doing
quite a few miles. Next day went out again and after 3 or 4
miles thought I had a rear puncture because it was moving around
all over the place. I pulled over and could smell petrol and saw
all the smoke, hit the kill switch and got off bloody quick, I
really thought it was going to go up in flames. Turning the key
on again after it had cooled down I could see the fuel spraying
out all over the place and could just about see that the
connection had blown off. An easy fix but that connection is a
pain, whether it’s getting it off or putting back on.
