need to replace fuel pump
 
I need to replace the fuel transfer pump on my 95 CTD. It looks like the only way to get at it is to first remove the starter. Is that right or does anyone know of some other angle.
I'd like to line up all automotive engineers and kick them where it hurts.[verymad]

Some people remove the starter, I don't remove anything.
What helps immensely is to toss the stock pump bolts and replace with a pair of 8mm x 30mm x 1.25 pitch studs with nuts.

If you do remove the starter you should install heavy duty contacts from www.fostertruck.com since you most of the way there.

studs
 
Bill,
Thanks for the size of the bolts/studs. That will surely help on reassembly.

You may want to crank the motor also that the LP is not on the high point of the cam....

I replaced my lift pump earlier this year. I started by removing the starter and
ended up removing the left wheel and inner wheel well cover. It was alot easier
getting to the fuel lines that way than from underneath.
I too also replaced the mounting bolts with studs which made it easier lining up the pump, pre-heater and the new gaskets.
P.S. While your down there replace or clean the screen in your pre-heater.

Pump is dead
 
I got the pump off today and when I pushed the plunger in it stayed in.
So I ordered a new pump, A Cummins. The old one was obviously original. It had engine matching paint on it. 343,000 miles.
I came accross an article that suggested removing the fuel preheater. I'm inclined to do that. (one last thing to cause trouble later) I live in S.E Mn, don't Plan on the truck being a daily driver, but do want to trust it in the middle of winter if I need to use it at O deg. or so.
Has anyone in cold climates removed it and do you suggest doing so? How many are just hanging there not working, doing nothing?

As long as you always have the correct amount of anti-gel additive in your tank there is no need for the fuel heater.
I been around diesels for a very long time.
First and only time I've seen a fuel heater like ours used was on a Dodge.

Thanks Bill
I think I will delete the heater. This truck Is my "heavy hauler". I have a Dakota for everyday light stuff. Though the diesel gets 5 mpg more. So only an occasional winter trip fot the CTD.A little anti gel won't be so bad.Plus it's good for the whole fuel system. Part of the reason for deleting it is that the curved hose from the pump to the heater needs to be replaced ( a 5" hose) and the price I found was $25. That's crazy! I wish that parts for These PUs wern't so high.
You've been a great help, Bill

Normally, people delete the heater (puck) and leave the pre-filter

Got mine from the local Ace Hardware.

Cummins would not know where to find a part number.

I bought mine at Napa.
My trick is I use just one stud over and over.
Once I have the stud side tightened down screw in the stock bolt on the other side. Remove the stud and replace with the stock bolt.
Same stud has done at least a dozen pumps.
