Running until fuel light comes on
Today one of my coworkers broke down just after leaving the fuel station. He was driving a 99 F450 fully loaded when the low fuel light came on. He said he only drove 5 miles before he stopped. He said after he fuel up he drove 2 blocks and the truck started chugging and quit, and then would not start but kinda sputtered. I told him to pull the fuel filter cover to see if it was pumping any fuel and it was not. He said it sounds like the pump is coming on but is not pumping, I was hoping the filter was plugged. We ended up sending a tow truck which was no big deal. As a rule of thumb I do not believe in running that low on fuel. I have no idea if he was out when got to the station or he went 1 mile or 20 miles but just trying to figure out if there is a connection before it gets to the repair shop.
Thanks

Probably time to drop the tank and clean the pick up foot or the screens in the mixing chamber. When you run it too low, you end up sucking up whatever debris is in the tank and it can plug up the fuel intake.

Yeah, drop the tank. Sometimes tings fall off or pickup lines crack causing you to run out of fuel early. I ran out like 5 times before I dropped the tank to find this duckbill thingy fell off. Did the in tank mods and no more problems

It will pump fuel and fill up the bowl, but it will not allow the fuel to be pumped into the heads. The fuel filter needs to be installed and the lid tightened down for it to depress the plunger inside the stand pipe to allow fuel to flow from the bowl into the heads.

This reminds me of a day years ago when I got a loaner car, diesel so everything said, but in fact it was a diesel converted to gas. I filled it up and ran about two blocks and it stopped. I checked it out and laughed, it was gas, had it towed back to the company and they gave me another. The old 350 chev days of diesels.

By no means am I trying to argue with you Chris, but on my truck when I first got it before I learned anything I brought my truck to a shop to test fuel pressure. He said he was to busy but if I wanted I could put his gauge on and drive it to test it. All it consisted of was a cap with a nipple threaded in the middle of the top of the cap. It did not have a filter in it nor was there anything depressing the valve down on the stand pipe. Now the pressure on the gauge did read only housing pressure so I don't know how much pressure the injectors were seeing but the truck did run as good as usual as far as I could tell and it ran at least 2-3 miles down the road. And also for anyone reading this, the way I just described is in no way a good way to test pressure. As far as I'm concerned your truck should never be ran without the filter!!
