old gas on fresh rebuild, bad to use old gas or ok ?
ok i got a rebuilt engine and i am going to be starting it up soon , the gas in it is probably 9 months old or so ( from last september when i bought the car or earlier)
would using this old gas be bad for my motor ? should i add some new gas to it ? should i drain it and add new gas ( this seems like it may be a pita ) ? any other good solutions ?

expect the mods to chew you a new *** for posting 5 topics in 5 minutes when you could have compressed them into one...
i would suggest draining it but i ran my rebuild with 9 month old gas with no problems. there is a drain plug on the fuel tank but getting rid of the gas is another dilemma.

i donno if i want to drain it because of the pita factor, i have a very small garage to work in and its a pain to get under the car especially in the back of the car lol

Won't be an issue as cars of this type had a pretty tight evaporative control system on them. If the cap was on the tank you won't have moisture in the tank.
Just burn it off and refill like you normally would.

I think it's worth the effort to drain the tank and have peace of mind.
My tank was really easy to drain, but it only had about 5 gallons in it. I put the drained gas in my wife's car--it mixed with the newer gas already in her tank and ran fine.

if you want to drain the fuel, pull the fuel sending line off the engine, pick up a male-male connector and about 5 foot of fuel hose, connect 'em up and drop the end of that line into a gas can.
Then, go look in your shop manual and it'll show you where the connector is (passenger side front of the engine bay, I think it's yellow or green) that you have to jumper (connect a wire between the ends) to enable "fuel pump test mode". This makes sure the fuel pump stays running longer than the (15?) seconds it normally runs when you turn the ignition to "on".
And then... drain the tank, and go to your neighbors saying "I've got some gas that was in my sports car, I didn't want to burn it in that car because it needs high octane, but it should be good for a lawn mower, do you want some?"

I'm not sure about your filter, but I would think a new filter with 9 month old fuel would be ok.
My big mistake with my rebuild was not cleaning the injectors. My gas was over 2 years old, and 3 injectors were totally gummed up and wouldn't spray any fuel. I wasted a lot of time trouble shooting a problem that I could have easily avoided.
At the very least, you may want to spray a little carb cleaner in each end of all your injectors.

^^^ He should be "cleaning" his injectors while the fuel rails are sitting in the corner of the garage for 8 months!!
And if Kevin built it, it's full of lubricants.
