I just converted my 49 f1 using the Toyota Saginaw conversion 1984 Toyota box kit
it works very good except the pump has a annoying pulsation and vibrating sound throught the cab
it does it either driving or sitting idling, but more when driving
I can't make it stop no matter what I try, including replacing the pump and changing pressures
has any one else had a similar problem, and how was it solved?
