90 E350 Fuel Pump question

Hello all,

I know this may be the dumbest question but. How many fuel pumps are on a 1990 E350 5.8L Van. I have replaced the one on the frame but i have noticed from Autozone and Advance Auto that there may be another one in the tank... is this true?

Also,

Would anyone have the fuse block diagram for an 1990 E350 5.8L. I bought the Van and it did not have the cover on it so i dont know what fuse is what.

Thanks for any help.

The fuse diagram is in the owners manual (p. 125). Check out http://vehicleownersmanuals.blogspot.com/2009/09/ford-econoline-e-150-e-250-e-350-owners.html

The electric fuel pump system consists of two fuel pumps: a low pressure boost pump mounted in the fuel (http://www.alldatapro.com/alldata/PRO~V136306184~C10889~R0~OD~N/0/34870081/56350053/56350308/56350314/34853741/34857029/34858641/34859372) tank, and a high pressure fuel pump mounted on the frame rail.
