[xj-s] leaking gas tank 90 xjs conv.HELP!

I have just finished an exhaust upgrade and here comes a real pain
in the (…) Opened the door this morning to take an early
saturday morning cruise and the smell of gas nearly knocked me
out when I opened the door.I took every thing out of the trunk
spare ,battery, carpet,etc. and inspected all off the hoses and
obvious places. I took the blak panel loose the sheilds the tank
and workd a loose the best that I could without taking the lien
from the sump off.I found that right where the green lines comes
out at the bottom to feed the sump, that the tank was rusted on
the bottom edge their and when I wiped my finger there I fond
gas.Not the place I was hoping to find leaking. How hard is it to
remove the tank and how expensive is a new one, or can this one be
patched, welded rather? where do I start as far as draining the
tank it is over half full. any help would be grately
appreciated.–

Removing the tank is a general pain. Your best bet is to buy a new
tank. If this one is rusted through in one spot, that means that the
rest of it is probably also rusted inside. Buy a new tank and install
it. This will also minimize your down time as you can just buy the
new tank and then remove the old one and put in the new one in the
same day.

My suggestion for draining the gas out is to disconnect the fuel line
going to the fuel rail, put it in a gas can (or several since you
have close to half a tank), then just short out the fuel pump and let
it run and drain the gas for you.

Not trying to be a smart*** but is it possible to short out the
fuel pump without sparking? - what with all the petrol vapours in
the work environment and such.–

Well, I’ve never set myself on fire doing it. That said, it would
probably be a good idea to make sure the area is well-ventilated,
etc. Alternately, what you could do is short the terminals with the
power OFF (so there won’t be a spark), and then turn the key to the
“run” position.

Nice work-around there, Ted. Now we know why I’m not an
electician. :)–

I’m the guy you read about who blows himself up looking in the tank
with a match…so…being allergic to mixing gasoline and
electricity I opted by-pass the technologically correct way to
drain fuel by connecting a rubber hose from the tank where the fuel
line comes in. It’s low on the tank so I ran the hose down and out
to a couple of empty five gallon cans (empty…duh). Anyway, I let
gravity have its way…worked fine. There was very little fuel left
in the tank when I got it drained but a little tilt and turn got it
all. Be sure and open the filler cap to equalize the air pressure
upon draining.

The only other problems I had was getting the tank itself out
(suggest using two people), also the rubber vapor boot up around
the filler cap on the inside of the trunk (it tears easy) and of
course, getting the tank filler neck and cap assembly loose from
the car. Boy what a fun job :frowning: but oh so rewarding when done!
