96 7.3l psd 4x4 recently i fill both fuel tanks and about a day later the truck started to run crappy.. the engine idle fine i think but when i pull out an drive it down the road and shortly afterwards the engine starts to bog down with no power if i step on the pedal i notice that blue smoke comes out of the exhaust. sometimes if the truck bogs down really bad and i pull over to the side of the road the engine stalls out, i sits there and wait for about 1-2 minutes and the engine starts again.

i changed the fuel filter and air filter but no luck still have the problem..please some advise will be helpful
thanks rob

one question about cleaning the fuel regulator screen ?
i took the 2 -10 mm bolts off and i pull away the regulator from housing ...what is the bottom tube that connects the regulator it looks like its on the bottom of a bowl like thing...mine came out and i pushed it back in nothing seems to be leaking is this ok? my sceen was really plugged as i was cleaning the screen it popped out and i cleaned it with gumout also the hole thats in the housing on the other side of where the screen goes was almost plugged too. i have never cleaned this at all and the truck has 81,000 miles on it...lol

i have read that putting a 3/16" ball bearing in the fuel pressure regulator will make the truck run better...is this true and where do you place the bb? do you drop it in the hole of the regulator and then put back the triangle adapter and spring in afterwards then seal it with the plug?...will this work in my truck?

thanks rob

everything is factory settings no chip performance,
so i guess the pressure will be fine?
i need to pick up a gauge to really check it.
also when i cleaned the fuel regulator screen the plastic plug in the regulator snapped in half but its still in there (both halfs) for the time being ,,,a new one will be here tuesday i hope. should i be concerned till then?

problem was resolved by replacing the fuel pump...as soon it was replaced the power was resupplied just like its suppose to be.

if i recall its about $100 at autozone the job entails removiing the whole filter housing...replace all the hoses ( the right type of hoses too) that connect under to the housing and to the fuel pump too. the toughest part of the job is removing the bango bolt from the fuel pump, its even harder to put it back on, but if your a patient man you can do it without removing the turbo pedastal and turbo dont forget or lose the washer that goes around the bango bolt because it will leak diesel fuel without it. good luck rob
