Greetings;

My 'In-Tank' fuel pump failed [in frt of house thank goodness]. {I pulled filter & wife turned key whilst I witnessed nothing entering fuel canister.} Truck was idling for a few minutes as I unlocked the house for bathroom run. What are chances I cooked the HP pump as well?

Local dlr says 6 days backlog for another pump. Anyone recommend wait for OEM pump or suggest a better aftermarket unit? The dlr will be calling soon for an answer from me re: their job ticket.

UPDATE: Local diesel repair shop [good guys, been there, good service & prices] HIGHLY suggest to me to have a FASS 95 installed. Their experience shows them that the in-tank pumps are only lasting up to 50K miles! That's 2 years for me! So $1100 @ dlr or $1500 [incl $190 htr option] at Hucksdorf Diesel?

Thanks for watching.

Mine failed in the driveway also... Glad I wasn't on the road, I put a AirDog 165 on three weeks ago, it's quiet and easy to do, (except the dropping of a full tank of fuel, at least DC left a suction port to pull out the fuel from the module):D
 
In tank pumps are quite reliable I have over 80k on mine . I question the FASS and Airdog as you can't replace brushes and they are quite noisy.
 
Thanks. I called NAPA & ordered a Carter in-tank replacement pump for $230. A friend is a hvy equip & diesel mechanic. He'd be glad to do the job. I'm so lucky to have options, after all.

Whatcha think the odds are that I trashed my V44 pump?
 
Did you have the cannister mount pump changed out? You are 04.5 year those failed terribly. The high pressure pump is the CP3 and no you probably didn't hurt it as the Duramax doesn't use a lift pump.
 
The in-tank pumps have actually proven to be quite reliable, though the fuel filter canister mounted ones are notorious for failing.
 
In-tank pumps last the longest when you don't run around with LOW fuel level in the fuel tank. Low fuel level lets the pumps overheat.
 
I would check for an electrical problem first. Make sure all the connections are good and there is power to the pump.

Well, if its the 04.5 in your signature, it lasted almost 10 years... thats pretty service life. I would simply put another in-tank pump in it and drive it another 10 years.
 
When my OEM failed I went with the airdog rather than have the warranty cover the cost of the in-tank pump fix

FOR THE VERY REASON YOUR GOING TO EXPERIENCE, HAVE FUN DROPPING THE FUEL TANK
 
BobV: Dlr diesel tech diagnosed as bad pump. He/she verified good signal to pump, but no response.

Wingate: Yes, my original LP failed @ 35K miles & replaced with the in-tank variety under warranty.

Motorhead: I rarely let fuel level drop < 25%, 'cause I've been caught short doing 'emergency' runs for family, etc. When actually traveling, I keep it at 1/2 minimum, using aux tank. Then if Aux tank runs out unexpectedly, we've got min. 150 miles to get Clyde a drink.

I've been using Lucas Fuel additive for years until I read the 'lubricity' report going around. I've since been using Diesel Clean, Stanadyne or some premium 'ashless' 2-cycle oil. I would hope these 2 efforts helped keep my pump running for 210K. I don't mind being lucky, but it's scary to be depending on it, eh.

Thanks all for your input.

Your guys that are bashing the in-tank pump are full of it and just trying to sell their pump. The 50K line is the biggest lie I've heard in a long time and I wouldn't trust anything they say after a line like that.
I have that FASS 95 pump only because the in-tank setup wasn't available yet. If I had it to do over I would use the super reliable and quiet in-tank system.

Prairie Dog: Thanks for the encouragement. FYI after looking at the replacement assy., it seems the pump is at the top of the assy., and it's pickup tube extends to the bottom. In anything less than a 80% full tank, it seems the pump body is exposed. Wonder if the 25% minimum tank theory is valid re: cooling?!?

I didn't take a pic at the time, as I just thought of it. I'll try to share it later today for general interest, as it won't be installed 'till Wed.

P.S. When truck died in front of house, I had my new 5th wheel attached. Thanks goodness I wasn't in the middle of backing it onto the driveway! Their conventional '450' tow truck lifted my frt wheels & proceeded to back the trailer in for us to get it off the street. Stealthy we're NOT!!

That's what usually happens to me! Mine actually cracked the fuel port and was spraying diesel all over the yard... So long story short, pump ok, resin humm seems ok for many
 
My 04.5 pump failed with my frail FIL in the truck at 35K. :eek: In tank pumped installed under warranty, but tech gave the OEM pickup assembly back to me if I chose to go with a aftermarket pump/filtration system.
 
Almost every gas powered car and truck built since the mid 80s have had EFI and a in tank fuel pump. These pumps are VERY reliable and the same goes for the pump in the Ram diesel since 2005. I personally have a combined 200,000 miles between my 2005 and 2011 and have no fuel pump problems. If I do, I will replace with another in tank. IF you need the extra fuel (MOST people don't) from an aftermarket pump that would be different, but there failure rate is worse than the factory in tank pump.

I think you might be looking at it upside down, it's nearly at the bottom.

I am on the fence with what I will do when my fails. I like the reliability and sound of the in-tank, but I want to have a f/w sep on the suction side....
 
If the retro fit pumps were the same as the OE they are at the bottom mostly submerged. The OE installed pumps have been dead reliable in their usable range. I have over 230k on the original and it still puts out 7-8 psi at an idle.

Yep, same problem here. None of the other solutions seem to be anywhere near as reliable as the OE pump. There a re some good pros but still not a perfect solution.
 
When the in tank failed on my 03 with 356k kms ( about 222k miles ) I replaced it with an AirDog. It is quiet and has 2 filters on which are easy to change and obtain. No regrets. I was changing from a flat deck to a box so I installed it then. David
 
I had the in-tank lift pump conversion done on my old 2003 when it had about 100K miles on it (I was having a separate issue with the tank module and had to be replaced, so it just made sense to have the conversion done). I put another 75K on it before I sold it last year and had no problems. I believe that the FASS and Air Dog pumps supply more fuel to the CP3 that the OEM lift pump does. Unless you seriously need to have that kind of fuel flow, I would go with an OEM in-tank pump replacement.
