Re: Fuel line to carb
I believe I was the one that made the observation. Agreed, the pump discharge pressure is only 5-7 psig, but it can spray a lot of fuel in a short time at this pressure if the line comes loose for any reason. A base model mechanical pump operating at 6 psig will flow about 40gph which is about 0.7 gpm and in my book that's a lot of fuel if its going the wrong place. A scenario in which a pinhole leak develops in the hose or a clamp starts leaking a spray at a connection could be worse than the hose completely disconnecting if the motor and headers are hot. This is why the OEM setup incorporates rubber lines on only the suction side of the pump and hard lines on the discharge side with threaded fittings. I don't know about overly dramatic, but everyone has a different level of comfort with risk and for a few bucks why not minimize a possible fire risk. Given that OEM's will do almost anything to save a few pennies per car, if rubber was deemed safe for this configuration I guarantee they would have used it. If you're going to use rubber, at least get hose with a liner that will hold up to the lousy ethanol fuel that will rot the line from the inside out. I didn't mean to be critical of anyone's setup, just thought I mention the risk in case it had not been considered.
