fuel tank check valve

[Kneale Brownson]

Haven't heard anyone who's installed one of the smaller diameter fuel pumps with the internal pressure damper report such problems.   Maybe that's a good reason to use the newer pump?

before it starts, than it slowly starts to fire (sounds like fuel starvation), 
push pedal down, starts, sputters a second than is fine.

My old 5000 when through 2 of them in 200k miles. This is the first on my 
200. I guess it is a fairly common issue.
