Bad map

[Arthur]

Hi all.

I have a noisy map signal. I use a vacuum tube t-pieced from the fuel presure regulator. In some log from people I've seen far smoother map signals. Should I take map somewhere else?

Map signal definately needs its own dedicated feed

 I had an identical noisy map signal as yours and solved it by putting in a medium sized fuel filter (about 50x60mm) inline about halfway along the pipe, it smoothed out the signal perfectly!
