92 F-150 4.9L Fuel Delivery Questions

2nd owner, 225k miles, E4OD, single tank

​​​​​​Hot start issues similar to vapor lock. After driving and coming up to temp it is difficult to start after shutdown for approx. 15 min, after 30 min. starts OK.
So today I hooked a fuel pressure gage to the Schrader fitting after sitting overnight. Ambient temp. 80 deg. Prestart pressure with koeo; 1 turn of key 10psi, 4 turns 20 psi, pump runs for approx. 1 sec per turn.

Cold engine running, 45 psi, rev and drops to 42 psi. FPR disconnected 45 psi, Vacuum at 20 hg idle

Hot engine prestart koeo, pressure released, 1 turn 8 psi, 2 turns 18 psi, 4 turns 32 psi.

Hot engine running, 45 psi,rev and drops to 40 psi. FPR disconnected 45 psi,

Hot engine off, 54 psi, 1 min 54 psi, holds 54 psi until 15 min then drops to 48 psi after 20 min

FPR replaced 25k back approx 6 yrs ago along with fuel filter. So I'm thinking injectors are OK, FPR OK, filter needs replacing, maybe tank filter\sock next, then high pressure pump.

Does this truck have 2 fuel pumps, 1 in tank and one outside?

What else could I be missing?
