Hello all! First time Corvette owner here and it's an 87' that has been sitting in a garage for the past 6 years. I've had this vehicle for about 2 weeks now and the first thing I'm attempting to do is check/replace the fuel injectors, drain the almost full gas tank and possibly clean out the fuel lines. The question I have is for how to clean out the fuel lines. The fuel pump has 3 rubber hoses going to it which have been disconnected and the fuel rail has been removed from under the hood. Does anyone know if it is or isn't ok to blow out the fuel lines with an air compressor to get the bad gas out of them? If it's not recommended does anyone know of a better way other than removing the fuel lines completely? TYIA
I would send the injectors to FIC for cleaning ONLY IF they are not Multecs. See pic below. Beyond that, If you just drain the old gas, change the filter, you should be fine. That little bit isn't going to hurt anything.

I have done a good bit of reading and I have seen the recommendation of basically trashing the Multec injectors. Luckily I don't have those but you don't think the little bit of fuel left in the lines will harm anything once I get the tank emptied and filled back up with fresh fuel or were you talking about the little bit of fuel that might be left in the injector itself?

That little bit of old fuel in the line isn't going to be significant. When you compare less than a cup of stale fuel to a 20 gallon tank of fresh fuel, what would the difference be? I would take the injectors for cleaning because of varnish build up. Ask Jon to give you a "before and after" and you might see the difference. Plus the injector basket filter would be changed too so....
I'd be more worried about the fuel in the injectors varnishing the injector pintles. Hence the recommendation for sending it for cleaning.
