How to start after running both tanks dry

1 Answer

140

This may or may not help you, but here goes. I have two of these old Classics with the 4.9 Liter engines. The only problem I have ever had with either one of them is with the dual tank fuel system. I've done some of the work on them and my Ford dealer had to get involved a couple of times. My Ford mechanic said to never run the tanks dry, because they will pick up every little bit of any debris in the tank and plug up the filter on the in-tank fuel pumps. He also said it is a good idea when filling them up to stop as soon as the pump clicks out and don't keep trying to keep squeezing gas in until you can't get any more in. I also put in fuel stabilizer about every two months. My trucks have been working fine for a long time and I do like the dual tank system.
