Most time on the 93 IF the Filter is restricted or the Lift Pump is failing it will turn on the Fuel Filter Light there is a Vacuum sensor on the Filter head that senses this condition.
Correct IF the tanks are full you can forget the shower heads being the issue .. this is why I asked how much fuel it had in Post # 2

One of the common problems,is the plastic screen eventually disintegrate over the years and crumble and fall apart.That's s different symptom than your having though,so.I just didn't read all the way down to see all your symptoms so don't pay much attention to that lol.

Just seems like a lot more work to disconnect things and stick Hoses in buckets and such...
He could probably Spray that IP with some water in a spray bottle and find out if it tightens things up
Seems like it is warmed up when the problem happens.

why is the smooth Idle now a thing of the past ???
"Replaced the lift pump, got the air out of the fuel lines and now the smooth idle is a thing of the past." DO you mean that it Fixed the issue or made it worse ????

I replaced the short section of hose between the hard line and the fuel into the fuel pump. I see that there is air getting into the system somewhere between the fuel tanks and the fuel pump.

Also, I just noticed that when I idle up there is a lot more air intrusion if that helps at all.

Looking over all the fuel lines, which are all rust free, and I'm having a hard time finding where the air intrusion could be. Does anyone have any helpful tips to track it down? All I know is it's before the fuel pump.

Hope you got it straightened out, I had a similar issue with my truck shortly after I got it... after replacing a few unnecessary items, I found out the pickup lines in the tank had broken off and would not pick up fuel when below 1/4 tank! still running like that 5yrs. later, just switch tanks at a 1/4....one day I'll pull the bed and change 'em (but not today

What causes this to happen? I just had this experience and now it won't start. It did it the last time I drove the truck but it didn't die, it surged a couple times and then smoothed out. This time it started, turned over a few times, surged, died and won't start.
