Does not matter as it will mix with the fuel either way you do it.
Mix it with the fuel, usually just put it in the fuel tank just before filling up with fuel
As long as your fuel treatment contains a detergent. Xtreme Fuel Treatment contains a detergent and a demulisifier and polymerization dispersants to clean injectors, separate water and break up sludge.
You may have picked up a little water from the gas station. I suggest putting a dry gas or fuel treatment into the fuel tank for the next couple of fill ups.
It should start up after it has fuel preasure. Check the fuel pump and relay. i ran out of gas and had to put at least three gallons in before it had enough fuel to restart. the pick up tube on the fuel pump is probably broke or you were parked on a hill
No, the flush oil is to clean the parts of the engine that are oiled. If you put it in the fuel tank it will block up tour fuel filters and your carburettors.
check your fuel filter, and put gas treatment when you have and empty tank. It could also be a spark plug misfire. Sounds like it is time for a good tune up.
You can put as much as you want up to the capacity of the fuel tank which is 70 liters or 18.5 gallons.
Put gas in it. If you don't want the light to come on, then another thing you can do is fill up before it's almost empty.
You might have air in the line, from the new fuel filter being empty. If you didn't put some fuel in it before you hooked it up, you probably just ran on whatever was alread in the line between the filter and the engine.
yes they could be stopped up or sucking air into the fuel system
take away all the fuel around the fire. this wont put it out but the fire will stop when it burns up the rest of the fuel
If the fuel rail does not have a Schrader valve, you will need an adapter to put in the line.If the fuel rail does not have a Schrader valve, you will need an adapter to put in the line.
