I have posted previously about fuel pump (lift pump) concerns with my 2014 Ram 1500 Ecodiesel. I have decided to go ahead and replace the lift pump to see if it corrects my issue (hard start when fuel is below 1/4 tank).
Has anyone here tackled the lift pump replacement on their own. I’m fairly mechanically inclined, and would like to do this myself if possible.
Any suggestions as to what pump to purchase and helpful hints for the replacement procedure would be greatly appreciated.

Thanks for both of your inputs. I have read some other info recommending lifting the bed instead of dropping the tank. I may give that a try.

And I appreciate the tip to use the OEM pump also. Sometimes saving a few dollars on the aftermarket stuff is a false sense of economy.

Thanks for all of the advice. I have been putting off the fuel pump replacement by keeping the fuel level well above 1/4 tank to avoid the hard start condition and avoid the cost of a fuel pump replacement.

Procrastination has paid off once again. With the recent FCA Ecodiesel settlement the lift pump/low pressure fuel pump is now apparently covered under the settlement’s extended warranty coverage. I took my vehicle in for the settlement recall and scheduled my fuel pump replacement a week later. The pump is on backorder, but should be in stock within a few days and the local dealer has confirmed that all replacement costs will be covered under the FCA extended warranty.

Thanks for all of your help on this site.

I've been experiencing the hard/long start problem for maybe 9 months now and the dealership has proven to be incompetent at fixing this issue. The dealership had my truck for 5 weeks out of the past 2 months and did not fix it. I've noticed a trend that my fuel level has been between 1/8 - 1/4 with around 75-85 miles remaining when I have the hard/long start. Today with ~75 miles to empty, my truck died while driving and this was first time this has happened. Did replacing your fuel pump fix the hard/long start issue?
Hello Crasch. Sorry it took me so long to reply to your post. For some reason, I didn’t see it until today. To answer your question, yes, the lift pump replacement solved my hard start problem that I was experiencing when my Ram went below 1/4 tank of fuel. Before the lift pump was replaced (under the RAM extended warranty due to the recall) I also experienced the vehicle dying on occasion when fuel tank was low. The lift pump replacement fixed both problems for me, and the extended warranty paid 100% of the replacement cost.

However, I now make sure to refill my fuel tank whenever I get to approximately 150 miles of fuel left (about 1/4 tank). I’m a believer that low fuel conditions cause these pumps to crap out prematurely due to the high temperature of the fuel that is returned to the tank causing the fuel pump to overheat.

Let me know if you have any other questions or concerns. Your dealer should know that this is a fuel pump/lift pump issue and that it is now covered under warranty. If he doesn’t, contact the RAM recall hotline and ask for them to intervene.

Sorry to hear it wasn’t under the extended warranty. I don’t understand why it would be out of warranty at 120,000, but it seems like FCA dealerships make their own rules sometimes regarding what’s under warranty. The good news is the lift pump you installed will likely outlast the OEM replacement pump that’s on back order.

I thoughti i had the same problem with truck shutting off around a 1/4 tank of diesel. But not it has done it with over 3/4 tank. My 2015 Ecodiesel has over 125k on it so warranty is over. Since it is doing it over 3/4 tank. Could it be something else? I just completely serviced the truck not more than 500 miles ago.

Any ideas? Thank you.
I wouldn’t rule out the lift pump. A hard start at under 1/4 tank is only the first symptom. At some point, the pump will fail completely and it won’t matter how much fuel is in the tank. The lift pump is covered on the extended warranty that can be up to 150K miles. I’d check to make sure before I spent and of my own money on it. You may be pleasantly surprised.
