Manifold pressure problem

I am getting fuel in the clear plastic manifold pressure line aft of the firewall. It blocks the line and I lose the manifold pressure reading (it slowly falls to zero) in flight. This has been a problem from hour one. I now have 95 hours on it. After clearing the line it might go 10 plus hours with no problem, then it plugs again. Any ideas?

where are you getting your manifold pressure? #3 cylinder?

Yes, #3 cyl. and using van's man. press. kit.

I have actually seen this issue once before. In that case, the transducer was mounted lower than the port fitting on the cylinder (no.3) causing fuel to pool in the line. Is your transducer and line passthrough high enough on the firewall?

Hope this helps,
