Fixing torn copper screen gas inlet
What glue would work to glue copper to brass (or copper?) and would
continue to work for years when almost continuously under gasoline?
(Only if I ran out of gas would it not be below gasoline**
A couple other questions further down.
I need to repair the reserve inlet from the gas tank of my new 1969
Honda CB450 to the petcock (and then to the carburetors).
Right now, it looks like a tube sock a little over an inch long, and a
little more than 1/8" in diameter, made out of copper mesh, copper
When seen from a distance it looks like a zipper that is open a bit,
that is, the tube sock is torn down the middle on two opposite sides,
but there is still 3/4 of an inch that is good as originally.
It's meant to attach to the copper or brass petcock, where there is a
trace of it still attached but only the teensiest part is above the
level of the hole, not enough to attach the rest of the screen to.
The hole in the petcock is about an eighth of an inch in diameter,
although maybe it would be bigger if I could remove the remains of the
previous attachment of the original copper "tube sock". (I haven't
seen this part for two weeks and I'm not sure anymore, nor do I know
how hard it would be to get it out. I've never had a motorcycle
before, nor seen copper mesh stuffed in a hole.)
How do I attach the tube sock to the petcock??
My ideas follow:
I could probably repair the tears by using thin copper wire (like the
size of standard 4-conductor phone wire, and sewing each side
together. But I would think the 3/4 of an inch that is still good is
enough, right? I would only put it back to ther original length to
have a margin of error when I make some other mistake trying to attach
it. And that seems like a good reason, do you agree?
Once that is decided, how do I attach the tube to the petcock. Maybe
I should glue some rather stiff wire into the hole, and then glue that
inside the tube along the length of the tube, and run some glue around
the bottom of of the tube where it meets the petcock.
I have some wire that my friend who used to run/own a plating business
says is magnesium or something fairly uncommon. I can find out if it
matters what it is. It's quite thin and quite stiff. The newer
version of the petcock has about 2/3rds of the "tube sock" enveloped
in a copper semi-tube (open for 140 degrees of the circle the length
of the tube) so disabling part of the circumference of the tube screen
with glue should not unduly limit the capacity of the screen to admit
Is this a good idea, or better yet, do you experienced, clever guys
have a better idea??
My idea involves glue, and your idea might too. What glue or epoxy is
strong enough with two metals and will work under gasoline, and won't
I tend to use Devcon 5-minute epoxy for things like this, but I have
to look at the label again to see what it says about metal and
gasoline. Or maybe superglue, so I know there will be no chance of
the glue clogging the petcock inlet or the "tube sock". But I know
that label doesn't say much, and I rarely get superglue to stick to
anything. I don't know if I use too much or too little.
Maybe I'll use the Devcon around the bottom of the tube, next to the
petcock, where I can keep most of it outside the tube, and the rest
only as far in as the copper.
If the screen fails it's not the end of the world. There is another
screen in the petcock that can be cleaned by emptying the gas tank and
easily removing a little bowl from the petcock. But of course I don't
want this to happen 2 hours from home in the rain. There are two
inlets from the same gas tank The main inlet is 3 inches from the
bottom, and has no screen, because iiuc the crud doesn't exist that
high. It settles at (and near?) the bottom, and the reserve inlet
without the tube sock will be drawing gasoline from the very bottom.
Unrelated to my repair needs:
I've run out of gas 17 times in 42, but not for about 10 years, so
make that 32 years. I'm more careful now. I can't remember every
time but at least 4 of those 17 times, I've coasted, sometimes for
more than half a mile (One time a half mile on the elevated part of
the BQExpressway, down a ramp and into a gas station a short block
away (no lights)) and one time only 30 feet, into a gas station and
right up to the pump. (Twice I ran out just before the crest of the
Manhattan Bridge, headed for Brooklyn. Once I coasted over the crest,
and once I had to ask the guy behind me to help me push it about 10
feet, to the crest. He didn't seem to mind (although he barely had a
choice.)) Each time I made it across Tillary Ave, once with a green
light and once by blowing my horn and a traffic cop kept the cross
traffic stopped until I went through. Then another 500 feet into the
SAEEWAY gas station that was there in the 70's and 80's. (It must
have been called SAFEWAY, and then lost a trademark suit. So they
changed the name to SAEEWAY.)
At least two of the times I've had to hitchhike to a gas station and
back. The two times I remember, that went incredibly well, taking
only about 15 minutes total each time. One time an older woman picked
me up and took me back, and the other time, I got one ride in one
direction and another back.
But my string of good luck can't last forever, and I think it's ended.
I almost won a RT ticket for two and hotel accomodations in Las Vegas
and a celebratory dinner where I would have gotten a national award
for having run out of gas the most with the most interesting stories.
I was in the top five, and maybe second.
