I have been running a Isspro mech fuel press gauge for 1-1/2 years
needle rock steady, hooked Fass unit to vp44 and now needle is
pulsating real bad suppose the old grease gun hose will work?
Any one with the Fass run in to this?

 

Needle valve might solve it as well.




Just close it down all the way, then open it little by little till the guage reads normally.

(thanks to Shovelhead for the pic)

Thanks Phox.

 

I had a hard time finding a 1/8" needle valve, I went to my local TrueValue hardware store, kind of a small Mom&Pop store and they gladly ordered me one.
