F350 Sputtering
I was in my 88 F350 (4x4, 7.3, C6) and it started sputtering like it was out of fuel. Then it cut off on me right in the middle of the road. My fuel gauge doesn't work so I thought it was out of fuel. I finally got it to the fuel station and it didn't hold but a little over a half a tank. What could be wrong? I think it might have an air leak, but if so, where? Where do these trucks normally get air leaks and how do I find out where it is. Also i think these problems are related to when I pulled my boat, a big 23 foot boat, my dad pulled the camper trailer in front of me with his 01 Powerstroke. That boat is big, but that Powerstroke left the little IDI on those hills. The camper weighs 18000 pounds, there is no way I shouldn't be able to pull that boat up that hill as quick as him with the trailer. What could possibly be the problem?

First off..... you don't stand a chance against that PSD on the hills.... You'll need several mods to pull that off... Change your fuel filter, check the tops of the injectors for fuel.. The o-rings may be leaking. Your lift pump may be getting weak as well.

It may be the lift pump. I've been thinking about putting an electric pump on it. Is there any problems with putting an electric and a lift pump on the same truck? I believe I heard someone say that it might not be good. I had another truck with a lift pump and electric and it "ran away". I disconnected the electric pump assuming that was what it was, and have not had any more problems.

Andy, I was following two friends, one with a 27ft 5th wheel, the other 26ft trailer, both towed by new 2005 & 2006 cummins. We were going on a flyfishing trip in the interior of BC...I had 4 boats, 2-10ft, 12ft and a 14ft...3 on a trailer and 1 off the front of my truck to my headache rack...they left me in the dust and I pushed that 6.9 for she was worth...but other than that the truck ran great...its 22 years old!

Andy the block off plate is the same one used on a big block chevy motor.
It only costs a couple of dollars.
The fuel pump will suck in dirt and sieze up with no lines on it, why take a chance.
As far as keeping up with a Power Stroke, depending on the year it will have you out powered by somewhere between 40 and 115 HP.
The 88 was 185 HP the 96 was 225 the 2003 was 275 and the 2006 is over 300.
Your fuel problem may be cracks in the fuel pickup tube in the tank. Common problem and the gauge not working tells me it is about time for this problem to visit you. They both seem to happen close to each other.
