Default Manifold Pressure sender failure

I'm on my second manifold pressure sender in less then 70 hr. The last one failed in less then 4 hours. They are both made by Mitchell Instruments part #ISS CAMPESND. When they failed the gauge needle pegs full scale. The line from the engine is from Van's with a restricted firewall fitting. Only thing different from Vans instruction is the line comes from #4 cylinder.

The first one on my RV4 lasted about 50 hours. It was installed by the builder. I replaced it and the second one lasted about 8 hours. On the third try I found the instructions say to install it higher than the fitting on the engine. So I moved the location much higher. Number 3 only has about 7 hours on it now so we will see if that was the problem. If this one fails I'm giving up and trying something else. Good luck with yours. CG
