    Posted: 05 Apr 2012 at 5:14pm
today after a week away from her getting my new seeding in. I removed both sediment assemblies out of the tank bottom. I let a gallon run out of each nipple. I cleaned each assembly. In the top part above the fuel shut off needle both had foreign objects like cork which I cleaned then reinstalled. After hooking back up I let fuel run from right bowl to left 'T' just ahead of left bowl. Great flow. I then disconnected fuel line where it threads onto hand primer and let it hang there...and no fuel. The tractor is on level ground and tanks three quarters full. Fuel should just gravity feed out of the primer feed, correct? If it should then I know my restriction is between left bowl and primer. I guess my bottom line question is with the hand primer feed line disconnected, shouldn't fuel run freely until the tanks empty? Thanks, Dana, and hope y'all have a safe easter weekend!

there are 2 check valves in the primer assy. May have junk in them plugging their flow.

Sounds like the cork float has come apart. I'm not familiar enough with a 190 to know what components might be in place, like the check valves, but I'd remove the lines from the tee and blow compressed air backwards through the lines to blow out any accumulation of debris.
Yea, I can fix that.....

Yeah I have blown that line out several times. Ed theres no flow out of the sole line feeding primer. I've had primer apart it's fine. The main line runs from left sediment bowl 'T' to feed the primer. It has a junction right near the front of the battery box. Now that I have the sediment bowls and interconnecting line flowing nicely, I'll check the flow at the bat box junction. I will track this restriction down tomorrow! Thanks, Dana
