I have a 1976 17' Galaxy with what looks to be about a 25 gallon aluminum
tank mounted up front. The previous owner was using a portable tank for
the boat because there is a clog from the other tank.

Here is what I have done-
-Tried to blow (just by mouth) back through the tank (did not work)

Many tanks have an anti syphon valve at the outlet so don't be too
surprised that you can't "blow" back against it.


-Removed the hose on both ends and made sure that is clear by blowing
through it (it is fine)
-removed the nozzle that screws in the tank and replaced the one it had
with a new one (the old one had some kind of a flow back preventer on it)

Oh OK that was the anti syphon valve, sounds like that's not there anymore,
so take that all out again & put a piece of wire or such in there & see if you
can unblock it???


-Tried removing the tank (boy thats a job) I spent about 4 hours on trying
to get it out, but the way the boat deck is laid out it probably wont be
able to come out without many hours more work.

Not uncommon to have to cut the deck, repair the tank then glass the deck
back in.


-I have drained all the fuel out of the tank that I could, it is still
clogged.

-I thought that maybe if there was some kind of a line flushing fluid that
you would suggest that would be great!! The problem is in the tank itself.
I dont really want to start jamming a coat hanger in there down the line (I
can see when I move it to the hole where the gas cap is normally) ( I have
the tank loose in there still) There seems to be a screen type unit in the
tube, I think it belongs there?? I am willing to punch through it down the
tube but I just want some support on doing that first.

Yes but try to get clear access from the outlet hole first, making sure you
removed any filters, anti syphon valves etc. After that well you have to clear
it so............ don't be shy.

Be careful of course even when apparently empty the tank is a fire or worse
risk & pieces of wire into an essentially insulated tank can risk a spark, not
a huge risk but be aware.



Right now I have it hooked to a hose and I am trying to run some Carb
Cleaner back down through it to see if that will remove the problem.

With the anti syphon valve gone & the cap removed you should be able to get
some compressed air in there??? Again be careful tanks can't take much pressure
& you'll be surprised how easy they are to damage.

Certainly a last resort but even consider hooking the garden hose to it
(cap off of course) & really give it a reverse flush out, once it's clear you
can deal with getting the last (or almost:-)) of the water out, but it'll be
clear.

Good luck.
