There isn't one as such. You would have to disconnect it a little to drain it.
There is none.
Drain the tank, replace fuel filters, refill with gas and hope for the best.
You can not. There is an anti siphon valve in the filler neck. You have to remove the filler neck from the tank and drain from there.You can not. There is an anti siphon valve in the filler neck. You have to remove the filler neck from the tank and drain from there.
The only way is to pump the fuel out with a small hand pump.
A"drain pump" machine uses a drain tube that is higher than the the level of water in the basin and therefore uses a mechanical pump to empty the tank overthat threshold pipe. A "dump valve" drain uses a mechanical valve at the bottom of the basin and simply opens to drain the tank.
Purchase a small inexpensive hand pump. Use this pump to remove all the fuel from the tank.
if you are not going to re use the tank you can drill the plastic, there is no drain plug, the best thing to do is to run it low then remove it, if you still need to drain it you will have to take out the fuel pump and tip the tank upside down
The petrol is pumped from the tank to feed the engine.
If the tank, shut the water off and drain with a hose on the drain faucet on the bottom of the tank. The pressure relief valve can be replaced (however a PRV is meant to drip, it has to expand.), so can vacuum breakers and the TP valve.
The petrol engine will just not run. No damage will be done. You will need to drain the tank, flush the fuel lines, and replace the fuel filter.
yes
oooh, put petrol in?? nice! You can either remove the tank and empty it by tipping it out of the filler neck, or you can siphen it, by doing this though you wont get all the fuel out. If you have put unleaded in, i suggest you take the tank off and make sure you get all the diesel out, although diesel isn't as harmful to a petrol system as petrol is to diesel. Make sure you fill the tank fully once you have refit the talk to dilute the remaining petrol as much as possible.
