Had the truck since Fall 2014. I like to do long road trips and sometimes can drive up to 2-3 hours for work in a day. Longest one was Los Angeles to Glacier National Park in Montana.

Here's what I replaced so far with all OEM parts

New Radiator and hoses 135,000 miles
New fuel pump 130,000 miles
replaced the failing air ride with blisteins at around the 130,000 mark
New alternator will be going in next week.
What else should i replace?
Which leads me to the fuel pump? Should i replace the fuel pump? I really love this truck and want to keep as long as i can.

It says you replaced one at 130K so which pump are you referring to?

 

Should i replace the fuel pump?

You have two pumps.
(1) CP4.2 Pump (also known as the high-pressure fuel pump) which is under a recall
(2) In-tank lift pump

The in-tank lift pump will eventually wear out, but there doesn't seem to be a trend. Some fail before 100,000 miles and others have lasted over 400,000 miles. My buddy with a 2015 EcoDiesel went 410,000 miles on his factory lift pump before it failed.

 

I would not pay out of pocket for a High Pressure Fuel Pump. The recall will take care of that for free

 

I got AAA with 250 miles of towing. I have a 160,000 mile Ecodiesel and a 150,000 mile Subaru Outback, figure eventually I'll use it. I'd only replace the in tank pump if it gets loud as @Crosshairs did. Not letting the tank get too low would be good insurance. Had one fail at around 250,000 miles on my last hemi Ram, btw. Figure that pump had pumped a lot of gas in it's life.

 

Congratulations! Really, nice to see some ED,s of that vintage rolling strong. I did enjoy my 2017 for three years, it was a towing machine.

On keeping a used truck going, I'll say this. I bought a 1994 GMC half ton way back, it had 64,000 miles on it when I bought it in 2000 for $15,000.

When I sold it in 2011 for $4600, it had almost 225,000 miles on it.

I replaced;

The tranny, twice
The engine (with a bored out camed "RV" rebuild 350)
Brakes
Alternator
Starter
Battery
Tires (of course)
Shocks
The whole front end, ball joints, tie rods, everything

And other odds and ends, all tallied up? The cost of a new truck when you add the original used truck price to the repairs. I got a good resale price because I did work on it. I missed that truck too.
One way or another, you're gonna pay. But it might be a good time to "let go".

 

2015 with 176k, I believe lift pump is OG...have a spare to replace it just haven't gotten around to it. It hasn't changed noise since I've owned the truck (bought with 60k)...

 

My lift pump got noisy around 125k miles and failed at 150k.

 

I hope that my lift pump gives me some forewarning and that I'm alert enough to pay attention to it.

 

replace the intake.... hate to say it but i'd done that before anything else.

 

I would not throw parts on it if it didn’t need them. If the part was broke or need I would replace. After driving the EcoD for many miles I would suggest you trade it off before you get to 200k miles. These trucks are expensive to keep on the road.

 

These trucks are expensive to keep on the road.

As a general statement, I agree with you, especially if keeping the truck emissions compliant. With that said, there's been a few high mileage EcoDiesel owners who have gone 300,000+ miles with very little issues. I've got a buddy that has over 450,000 miles. He hasn't had to replace many parts at all, but he's also deleted.

 

FWIW my lift pump has 266,600 miles and 6,955 hours thus far. Sometimes I add EDT sometimes I don't. Most of the time I run it well beyond the fuel light comes on.

 

It says you replaced one at 130K so which pump are you referring to?

Fuel pump, not water pump.

Sorry I meant water pump

Yes, we all know that now. Read my first reply with the included quote in post #2
He originally stated that he changed the fuel pump which is why I questioned him , he then corrected the post
