Recently got a 1982 FL250 for my sone to rip on. The previous owner used a gravity fed system because he said he didn't like fuel pumps. Everything was still there and I want to go back to using the original setup, problem is, no gas is getting to the carb. The hose is hooked up to the cylinder, and all the other hoses seem good. I changed the filter thinking it was that but it did not work. If I hook it back up to gravity feed it will run and I can see fuel coming to of the check valve nipple where I removed the hose to hook up to the gravity tank. Not alot, but there is some coming out. I quickly try to hook the hose back up the the check valve, it will run for 20 seconds and then die. I can see in the hose there is no gas getting to the carb then. Could this be a fuel pump problem?
If anyone can offer any advice it would be greatly appreciated. Thanks for taking the time to read this.
