Ford Repair: fuel pressure pump, ford e250, frame rail

Question
I have a 1991 ford e250 with a 4.9l A/T, I was told that I need a high pressure in line fuel pump. but I cannot find where it goes. It does have 2 tanks on it. Also I was told about a switch that will shut of the fuel pump if it was in an accident or bumped, i was told to check it and to reset it, how would I do that?  

Answer
Hello and thanks for the question...I'll try to help.
Your high pressure fuel pump should be located on the left frame rail........around the driver's door area. As far as the inertia (cut-off switch) goes all you have to do to reset it is make sure that it is fully depressed.
Hope this helps,
