I just did this. Got a real strong gas smell after the last fill up. It took 2 weeks of driving to get the low fuel light to come on! While I was too lazy to put a pressure gauge on the truck, it was showing signs of a failing pump check valve (prolonged cranking (vapor lock) on hot restarts). Butt dyno jokes aside, the truck is running much better with the new pump/tank combo. It is just enough of a pain to remove the tank to justify the extra cost of a new pump at the same time.

 

Yes in deed!! Removing a gas tank is not rocket science, but it is a job you really don't want to do, and Really don't want to do twice!

 

Doing a fuel tank (not that hard ?) Depends where you are doing it . On the ground it's not that easy. Have a hoist ? Then it's not as bad . Get all of the fuel out of the tank (or as much as you can ) Probably the hardest part will be your lines (getting them to release) I bought 3 different sets of release tools I'm glad I did . Very tight quarters. Once you get the tank down replace all of the small hoses that connect to your tank (mine where all rotted ) You will need some new tank to frame material . I used some blue skin. My pump was still working OK . I replaced the pump anyway do it once and your good for awhile LOL Herman

Nice new tank .

 

Rub a bar of soap across the leak..... To plug a leak in an emergency. Yeah replacing a tank isn't too difficult. It's usually pretty dirty though there's usually quite a bit of dirt on top and you're old emission hoses are crumbly. It's worth going and getting some new stuff for that before you even start

 

Yep, you going to do it do it right.
On my 1999 F150 they had a recall on the fuel tank straps many moons ago. They were rusting out and dropping fuel tanks. Or leaving them hanging.
A free fix with 2 new straps.
This was on a 1999.
Check yours if you have a 99.

 

You guys are funny, yet mostly helpful.
I don't suspect OP has had a leak for the past 10 years. Especially with fuel costs in 2022 would they allow a leak to persist.

 

Would Dove work? Ivory better?
Never heard of that.

 

The soap isn't soluble in gasoline. And you force it into the crack. Now having ethanol in your gas might change that from the way it used to be, when gasoline was all aromatic and mostly aliphatic hydrocarbons.

 

I am always thankful for a new emergency tip.
Like in the old days, Black pepper worked on radiator leaks.
Or your wife's nylon stocking for a radiator hose leaking.........on the road to get you to help.
I have heard of the stocking's working for a temporary fix for a fan belt too.
But these were for long time gone cars.
New cars or a pickup are just great with all the doodads' .........if they keep working.

 

Good to know in a pinch.

Years ago when I was young going to Buffalo in the 18 wheeler, I kicked something up and put a hole in one of my fuel tanks.
It had to be the one with no shutoff valve. It was about the size of a dime. I stuffed a rag in it and it slowed to a drip.
An old-timer stopped and saw my problem, he went over to the tree and cut off a branch with his knife.
He whittled a tapered plug and tapped it in. Worked perfect. He said it would swell up and last a long time.
I delivered the load to Buffalo and ran back to my yard in NJ.
I bet the fix would have lasted for many years.
