plowhand - the turbo does not have to be removed to change the fuel pump on a non-cali truck remove the fuel filter bowl, this requires about 4 fuel lines to be removed (i cut mine, there were factory and dry rotted) and two bolts at the base on both sides. once the bowl is removed you can access the pump. use a 1 14" box end wrench to remove the banjo bolt. if your wrench wont work it may need just a little mod, i did not have to do this but did have to try a second wrench to get at the bolt. once the banjo bolt is removed remove the 2 fuel pump mounting bolts and remove the pump. there is a tappet on the bottom of the pump, i have read on this site it can fall out, it would not be good if it fell inside the engine block. i did not have any trouble. putting everything back together should not be any trouble. the banjo bolt is a booger and the bottom fuel line is a SOB too.

the pump i described (under the turbo), is that the fuel pump or the fuel injection pump? trying to budget for a possible replacement, and theres about a 300 dollar difference between the two. if i replace one, is it a good idea to replace the other, also?

 

that is the ONLY fuel pump on the truck is the one you see in the valley. its the pump that takes fuel from the tanks to the fuel rails. there is not traditional "injection pump" on theese trucks. a fuel pump off ebay is about $80 for a new carter pump (which is factory) if its a federal truck the turbo dosnt need to come off

 

If your wandering what the fuel pump looks like look in my gallery it shows pic of pump on motor with turbo off so good view and lines runing to back of heads. If you replace it I would change the orings in the lines at the back of heads and the hoses that hook to it.

Hope this helps a little

 

well, next week im taking it up to north east diesel specialists in eastern connecticut. they worked wonders on my buddy's engine. will keep you guys posted as soon as i find out more.

 

ok, is it possibly the mechanic could have upped the power output of the engine somehow by adjusting the fuel pump?? he claims to have done so. also, the pump actually looks larger than what he replaced.

 

I'm not aware of any adjustments that can be made to the stock pump. He may have adjusted the fuel pressure at the regulator.

I'm sure if you do have a larger than stock pump this forum would be very interested in seeing it.

 

you got my attention.

do you have a picture?

as far as i know carter is the only one who makes a stock location fuel pump. maybe he shimmed the fpr?

 

not sure. ill get some pics for ya in the next few days. gotta tool around under the hood to replace an idler pulley and serpentine belt that blew off on the highway friday night (oops!).
