I'm a mechanic and a shop owner. Here is the truth, and if you had asked them you would have gotten the truth about it. When we do a fuel pump inside a tank, we remove the fuel as best we can. When you work on a tank you have all kinds of dirt that gets everywhere, and inside the tank is full of stuff too. When we let the tank down full of gas, we take it outside the shop and deal with it very "carefully" since we are dealing with a potential bomb. You have to use non sparking tools to work on it with, and when you remove the ring and seal, there is all kinds of dirt that gets into the tank. You can't help it!!! Since you can't get a hose down in the tank to get the fuel out safely, we just leave the fuel in it until we get it outside the shop. Once we remove the ring and seal, we then pour the fuel out into a hazardous materials drum. We purchase some fuel that is clean, and rinse the tank with it, and put that into the drum too. Once it is clean, we replace the parts, and add about $5 worth of gas to your tank. It all has to do with safety, as we don't wish to blow up the shop, your car, or ourselves, and we have to have clean fuel to put back into the car. I know that is an awful lot of fuel to waste, but if you have a better idea on how to do it safely, then I'm all ears.
Glad I could help. Good Luck!!!

You had the fuel tank replaced Why? rusty filled with crap ? Sometimes to much junk is in the tank to make to possible to save the gas. But when doing a fuel pump you should not have notice any difference in the amount of gas in your tank unless again the gas in the tank was bad in someway.I say your tech is getting free gas from you.

You are asking the wrong people... Ask the mechanic. At todays prices that was upwards to $50 worth of gas that he had to siphon off and you know he didn't flush it away. State law often requires mechanics to provide you with all the parts from your car if you requested it up front. Its streching it a bit but if you asked for the old parts then ask him about the gas. My guess is that the gas may have been contaminated (rust, debris etc.) from the old tank, but it was still your gas.

Otherwise deal with it and next time make a point about the gas up front. Road testing a repair should never take a full tank,

When the mechanic has to drop your tank, they have to empty the tank first. In many jurisdictions that is considered hazardous waste and must be disposed of properly and cannot be put back in the vehicle. Many fuel pumps are inside the gas tank which makes it necessary to drop the tank to replace it.

Deal with it.

The storage tanks that they use for the gasoline does not have any type of filter on it. If you were to try to put the gas back in the tank, after being in the open air for a long period of time, you run a couple of risks.....Some of the alcohol may evaporate, making the gasoline less effective, and MORE importantly, you may end up with some type of foreign material in the gas that may work it;s way into you brand new fuel pump and damage it. They simply do not take the risk over 30 bucks in gasoline.....Make sense?

When your going to get your fuel tank replaced why would you fill it up. It makes the job more difficult.

I have had a fuel pump go bad many times (different cars) but my gas is always there except maybe a gallon or so.

It sounds like your Mechanic.

He can't guarantee the quality of the gas that was in your tank when you brought it in.

Therefore, to guarantee his work, he needs to put in what he KNOWS is good gas.

It's just common sense.

Uh, I would say that someone is pulling the wool over your eyes.

I guarantee you that someone is burning the gas, if it's not you.

You should be checking your odometer to see how many miles he is traveling on your dime.

Good luck!

a lot of mechanics are scavengers
