bought this to fix fuel drain back problem

well Dave, I am having a hard time understanding how you can say that you bet my problem is still there when the problem is not still there. If everytime I start this car I have had to pump it numerous times for the past 10 years now I put this valve in it and now I only hit it twice and she fires, please explain this for me. wouldn't you think that if the problem was still there I would have to pump it numerous times. because if it was evaporating, putting the valve in it did not change the evaporating process. Sireland, I will let you know if it changes. Bill

A couple of reasons your problem could appear to be gone - you could have bought fuel somewhere different than your normal station and its formulation is different making it less susceptible to evaporation, or your ambient air temp since you have put in the check valve has been cooler, again preventing evaporation. No sarcasm, just stating real physics. Fuel simply cannot physically drain from the carb float bowl back to the tank,the same as your kitchen sink cannot drain through the tap. Hope your problem is gone away, good luck.

Dave
