My gas tank on my truck must have a small leak. For a couple weeks I
always smell gas outside the truck, especially after I drive it. I know
how to change it, but I'm looking for ideas how to pump out the gas.
I know NOT to use anything that would spark, such as one of those little
drill operated pumps, since the brushes in the drill motor spark.
One thought I have, is to disconnect the fuel line at the fuel pump, and
just use that (in the tank) fuel pump to pump it out and into gas cans.
Basically, remove the fuel filter and clamp a piece of fuel line to the
line and insert it in a gas can. Then turn the ignition key to the START
Does anyone know if this will work?
(Maybe those pumps are meant to shut off if the gas flow is high??? I
In the old days, I would have used a siphon, but the old method of
sucking it out with one's mouth is NOT an option. I did that when I was
young and stupid and got gas in my mouth. I know they sell (or used to
sell?) siphon pumps (a rubber squeeze bubble in a hose), but wonder if I
can get it into the tank, since modern tanks have that little nozzle
flapper in them????
* Of course I'll let the the gas level get low before I attempt this....
Any other suggestions???
I just replaced the filter last week, because the engine was running
rough. That's when I looked for leaking gas around the tank and did not
see any noticable leaks. Yet the gas odor continues.
*The rough engine situation was later found to be a bad distributor cap.
Besides the dist cap, I replaced the rotor and spark plugs too.
I got one of these things
(Amazon.com product link shortened)
to facilitate oil changes on my generators.
Been meaning to try using it to get some gas out of my F-150's tank....
I'm hoping maybe the hose is narrow enough to get past whatever is in
the filler neck that stops siphon hoses.
It would certainly improve the generator fuel-storage situation.
Anybody tried something like this ?
I've found that small engines generally have
an oil drain plug. I'd be using that instead
of a suction rig. Gets the oil more completely,
drains to the last drop.
Years ago, I saw a picture of some vehicle's
anti siphon lock. It's a ball in a cage, and
even small hose like this won't do.
Sounds like $46.50 spent on a good idea, but
not going to get much use from it. Sorry.
You must be a REDNECK of your gas tank is in the truck bed! <LOL>
Unless you have an old truck with a carburetor and mechnical fuel pump
on the engine, you have an "in the tank" fuel pump. How did you rig up
the fuel pump on a removable tank? Besides the electrical wires to
operate the pump, and for the gas gauge, you have a fuel line, return
fuel line, and probably a vent line. (Total, 3 lines, at least 3 wires).

Think 1968 Chevrolet C-10 truck with a short box. Got the picture?
Now, think 632 ci big block, fuel injection, 2 speed auto trans with a
5K rpm converter with a trans brake, narrowed 9" ford pumkin with 16"
Who needs a 20 gallon gas tank behind the seat? :')

I guess you've never heard of "fraim rail mounted fuel injection

Bosch OEM part - also used on quite a few earlier Nipponsenso EFI

I've repaired gas tanks in the past with JB Weld, and never had it fail.
Normally if the tank is still solid, but has surface rust, I will sand
off the rust, then coat the rust (or the whole tank) with undercoating,
before I reinstall it. If I have to buy a new tank, I'll probably spray
it with undercoating too.
I dont know how you figure it would be cheaper to replace the tank. A
tank costs close to $150. A tube of JB Weld costs $5.
But yes, I do plan to fix it soon. It's not safe and it's costing me
money for lost gas, even though I dont think I'm losing much. The hole
is probably on the top or upper side, and splashing makes small amounts
leak. There are no actual drips. I only smell the gas odor after I drive
it. If it's parked overnight, there is no odor. I've been keeping the
gas level at no more than a quarter of a tank, and I carry a 5 gallon
container of gas in case I run low, bcause in this rural area, a person
may have to drive 25 miles to find a gas station, and it's even worse at
night, because a lot of small town gas stations close at 9 or 10pm or

I'm just saying I would replace it, you can JB weld the leak and get a
few more months of use out of it, and either replace it, or get a new
ride, yes? Without going back to see what you're driving, what are you
