Does anyone know anything about the fuel pumps on the RD model macks. It's a 1999 and the throttle is not responding. I put a new throttle position sensor and checked all wiring to pump. One guy told me to just send it to mack house but if it's an easy job I will just do it. Please with any information about what I'll be getting into once I get it all tore apart. Email me at young_stedman@yahoo.com.
Thank you
