Fuel Pump PSI
#2

By fuel pump you mean Injection Pump and for a second generation truck it is:
15 to 18 PSI at idle.
no less than 13 under load and no less than 11 at WOT.
If you see anything less than that you need a new lift pump (transfer pump) or to at the very least change your filters. If you have many days of low pressure you will effect the health of your IP.
There are many options on this fix and many other items related to it.

There are several aftermarket lift pump kits that can help you with the low fuel pressure problem.
FASS is one way, Walbro 392 kit (the way I went) is another, upgrading fuel lines is another, just going to 1/2" fuel line from Vulcan helped my stock pressures out a bit.
Do some reading and find the kit that makes the most sense to you.
