Re: E450 wont start Reply #50 – June 02, 2023, 03:39:55 am Hi Bob; I remember that someone here has installed an auxiliary pump, so that if the main pump quit, there would be a way to proceed. Might not pass smog, or some other problem. I'm not sure about particulars. I believe this other person was obtaining gasoline through some other port than through the main pump. Maybe they will respond with some details. Found that thread here: Fuel Pump Replacement and Dropping Fuel Tank RonB
Re: E450 wont start Reply #51 – June 02, 2023, 12:53:09 pm The in-tank fuel pump consists of a pump, a filter, and a fuel pressure regulator. The filter may be plugged or close to it being so old. An external pump must operate at the correct pressure and be regulated to the pressure the particular engine needs.Too much or too little pressure would cause issues, possibly severe.The best choice is replacing the in-tank fuel pump.Larry
Re: E450 wont start Reply #52 – June 11, 2023, 10:11:36 pm when I changed my fuel pump i didn't drain all the fuel; but of course it wasn't full. Don't remember how much was left in it but I wished I had drained it because it is a Pain In the A@@@# to deal with the extra weight.
