bought this to fix fuel drain back problem

understand what you are saying vert. but the difference is that it didn't do that before I put the valve in it. I had to pump the accelerator probably 20 or more times to get it to start. That tells me the fuel had to be draining back. that stopped. If the fuel was evaporating out of the carb, I would have to pump it in order to get it to run. I didn't have to do this this time. I will update again if the problem comes back. It may. I am not saying it wont. I don't know. I am just saying that it has been sitting for days now it it started right up. will let you guys know if anything changes.

Please keep us updated on how it works out.
My dad's old truck will sit 3-4 months at a time, he is hitting 70 years old, so anything beats dumping gas in the carb to get it to start.
