Fuel Pump Questions

I have a 1989 E350, 460 EFI

There are 2 fuel pumps. One in the tank and one on the rail under the drivers side. The one in the tank is low pressure and the one on the rail is high pressure.

OK, so how much is low, and how much is high?

If you ask in the 87-96 F250/350 forum you will get more help.
I would say about 6PSI low side and 35-40 High side, but thats just a guess.
