I'm looking to purchase a lift pump for both my 2015 which is bone stock and my 2006 which is not. 2006 has duramaxtuner tuning, 4 inch exhaust, and all emissions stuff deleted. My 15 has nothing done to it, though I may add emissions in place tuning in the near future. Just not ready to give up on my warranty yet.
Anyway I've looked a lot of different fuel pumps and I'm not sure what direction to go. I live in northern South Dakota so I'm really hesitant to put a lift pump on with filters because it's just another point to cause gelling issues.
What are your guys thoughts? Filters/no filters? Fass, air dog, fuel lab? Thanks for info I appreciate it.
I have yet to install one, I have the same concerns although MA is warmer than Dakota. I plan to use the Fass150, based on my reading here and elsewhere it appears to be the best choice. I'm sure many people run different pumps with and without filters. Wish I could give you more specifics but i'm sure someone will chime in.
I was looking at doing the Kennedy lift pump myself. No filters but you can add them if you want later. I don't plan on having crazy power so it will support my needs.
Another vote for fass here. No issues yet to date, 1/4 tank or other. Airdog, fuelab, and Kennedy are all great choices also. They make heating elements for lift pumps, iirc fass has the hook up already. Not sure on that though, doesn't get cold enough here to worry about it. I would definitely get one with filters, extra filtration is always a plus especially on lmls. Something else to take into consideration is your warranty. If you plan on deleting and warranty isn't an issue then go for it. If not, some dealers WILL say the fass voids the warranty. My dealer told me they would not warranty the fuel system (cp4, injectors, lines, etc) if the cp4 failed and a lift pump was installed. Best to talk to them and ask first. They should have to prove without a doubt it was the modification that led to the issue, but we all know how that can go:grin2:
I've been running an airdog for a few years. 3 winters with no issues of gelled fuel. It's seen -40 without issue, that's with no additive and on the highway where my truck was struggling to maintain engine temps. Canada treats the diesel for winter though, you guys may have to hunt for a pump that's pre treated.
AirDog here in Chicago.
We have cold temps here as well, last few nights sub 0* temps. I run Anti-Gell and have no problems.
Gelled last year and actually narrowed it down to the junky stock filter.
I deleted the factory filter before winter and haven't had a problem with gelling since.
Good advice guys thanks. A couple of thoughts. First, I don't worry about losing warranty for a fuel pump. I have good connections at my dealership. If I deleted I would definitely lose it, but not for doing a lift pump.
Second, I looked at the Kennedy pumps. I know Kennedy sells a very quality product and his pumps have an excellent reputation. My only complaint with them is that they won't self prime if you run it out of fuel. Otherwise they are an option I have considered as well.
My friend just installed a fass 150 in his pickup. It works well and I like where they mount their pumps at as opposed to the air dog. The air dog I don't like how the filters hang down on the frame rail. Going to check out fuel lab and see where theirs mount and then make a decision from there. Thanks again!
Mounted my AirDog on the inside instead of the outside of the frame. Looks great and stays out of the way.
My AirDog motor recently sh*t the bed after 5yrs, I called them and they next day shipped the motor to me free of charge. I will forever support AirDog.
But I have heard FASS is the same way customer service wise, to me, its preference. Either or will work fine.

Did you ask why it voids the warranty.? If they have no answer or make a statement about emission point out the FASS has an C.A.R.B. E.O. number per California guidelines.
C20, I never asked. Same dealer quoted me over 700 to re-align the downpipe before that recall came about. Also tried showing them the it afterwards and they just kept saying it wasn't the same thing. No use to argue when I knew I'd be deleting anyways. For someone else it's definitely worth it especially if you have emissions testing and can't delete.
Hahahahaha. These smiley things are great. The thread wasn't started as a warranty thread, but a lift pump one. Keep it on topic, especially as the OP has stated he's already cleared it or is sure he won't have an issue. Silverlml was offering extra and useful advice. C20, chillax. Off topic threads suck
Would also suggest adding a sump to your list if your going to install a lift pump. I put a fass 150 on my 15 and it's awful loud you prime the pump and it runs for a few mins then sucks air again and starts cavatating it really needs to have a sump. So it doesn't fight to pull fuel through the existing line and straw just don't know how I feel about cutting the 3" hole in the bottom of my new truck
Would let it be worth the extra 10-15 dollars for the 150 over the 95 of you ever tune the 15 and bump the power up I would want the 150 just my .2cents
IFthe pump delivers what the manufacturer claims then 95gph is a lot of fuel (the stock ACDelco and Parker/Racor only flow 45gph). Pretty simple math, at 100mph lets just throw in say 15mpg that's 6.66 gph. The rule of thumb for a suction/supply pump is the suction is a minimum (larger is recommended) the size of the supply and a 5/8" would be just enough for 1/2" supply. The stock pickup in the LML might be 7/16" this is where a sump will help with the VOLUME on the supply side and eliminate cavitation.....
That's a good point. I didn't look at prices that close. Didn't realize that the price difference between the 95 and 150 was that small. I will go with the 150. As you say, then if I ever bump the hp I won't have to replace my lift pump.
