My truck has bren parked for a ling time, how do i treat the gas in order to start the engine without having to replace the fuel pump?
I would get a hose and siphon out all the gas and put fresh gas in.
It may already be too late, if it has sat for more than 3 months the fuel pump is most likely locked up, These pumps don't do well sitting, take the fuel filter line off of the out end, slide on a rubber hose that fit snugly on the filter outlet put the other end in a pail and just turn the key on, if fuel comes out then the pump is still working, then you can siphon out as much as you can, put in about 5 gallons of fresh good fuel, replace fuel filter, cycle the key about 3 times then try to start it. Please change the engine oil and filter first as engines will sweat internally and all of that crud will be in the oil pan. Then if it does start you can add some Techron to the fuel tank when you fill it up. Don't forget to change out the other fluids too, as moisture will build up there also. HTH
