Philippe, Two things may be the possibility. There may be a filter on the feed line of the sending unit. Later models definitely have one, not sure about 57. the problem is having to drop the tank to get to it. Do you have a vent line? If so, that may be plugged with something, try blowing air through it. Also loosen your cap and see if it flow properly. Might be as simple as the cap.

I removed 5 gallons from the tank (with the electric pump so it works well even to pull 1 ft higher ..), re-tried with pump attached to sending unit tube : same results: bubbles in the (clear) hose, very little and erratic flow in the jar. So, late test, i sent 50 PSI in the tank through the sending tube. "vraoum" i heard + noise of bubbles. I re-attached the pump and bingo, lot of fuel ( 5 quarts in 1 mn), no bubbles , etc... So there is "something" in the tank or at end of sending unit which plugs the tube !! What i don't understand is that the tank was cleaned and coated with special epoxy 3 years ago !!! It wasn't rusty or dirty before but i cleaned it perfectly before coating !! I haven't yet re-attached mechanical (or electrical) pump to fuel line but i think the problem is solved. But now i must drain the 15-20 gallons of gas before removing the tank ... -- Philippe COURANT (Pau, France)- Webmaster des sites ACCF et C-I-F Imperial 1957 Crown convertible Buick 1996 Roadmaster wagon - American Car Club de France (ACCF) : http://www.accf.com - Chrysler Imperial France (C-I-F) : http://www.ifrance.com/c-i-f - Cadillac " Standard of Excellence " : http://www.ifrance.com/accf-cad - SportsCars : http://www.ifrance.com/accf-sprtcar [Non-text portions of this message have been removed] To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm Yahoo!
