Fuel system recommendations

[EricViviano]

Looking for a little boost on a stock 02 5.9 HO with 217K miles. Mild power boost with fuel economy gains and smoother running engine is my goal. Your recommendations please.

Thinking....

Dynomite Diesel 50hp injectors
Boost elbow
FASS DDRP lift pump with relocation kit
VP44 from Thoroughbred diesel

comrade - my 01 2500 5.9 has almost same miles as your truck. do not buy fass . junk. i went through 2 of them. 1 was 2 weeks out of warranty and they wouldnt stand behind it. i ended up putting a frame rail bd pump on the truck and its fine. also ditched the stock fuel filter housing and went with 2 oil filter style filters - 1 filter and 1 water seperator. the washers on the stock filter housing developed tiny cracks in them, causing air leak, and fuel prime loss. 2 shops told me i needed injection pump. i figured out it was just a simple washer with a rubber insert causing the entire issue. cheers!

No luck with FASS huh? My concern with the AirDog/Fass style frame mounted two filter pump is cold weather. It gets very cold here for a long time.

i have had " old blue " out when it was - ( minus) 20 f in colorado. it did just fine....when it got to - 27 f i had to add anti gel. those were the 2 - 3 coldest days in recent history , however. also, paying multiple hundreds for a engine mounted lift pump, and having it fail within a year ( installed by a fass dealer too ) and having no support from fass really chapped my ass. cheers comrade!

You're going to find a whole slug of opinions on fuel systems... But just understand that there are basically 4 options to choose from based on what kind of power you're after and you're ability to install.

FASS has a whole line up of electric fuel pump systems to choose from.
Pureflowairdog is a result of family business separation from FASS which was originally AirDog. The two companies offered basically the same electric fuel pump products with different labels until they sold out to another company in the later 2000's. Unfortunately quality was compromised and people found that PureflowAirdog products were junk for a few years until they either sold again or decided they needed to step up their game. The word spreads fast over internet forums... Today I understand AirDog products are much better but I cant confirm how good.
Glacier Diesel offers a superior mechanical fuel pump system called Fuel Boss. It can also be fitted with or without a secondary priming electric fuel pump because mechanical fuel pumps cant run a prime cycle. The only problem with the FB system is because of where it mounts to the front of the engine, an aftermarket Fluidampr engine damper will not fit.
DTT also makes a mechanical fuel pump system called Assassin. Although some years back there was much debate about DTT's quality and ability to stand behind their product. Again, I cant say if thats ever changed but you'll see that Fuel Boss is more commonly used than the Assassin system.
BD also makes an electric fuel pump system called Flow-Max. Cant say what or how well its built but just pointing out that BD usually doesnt build their own products but rather relabels other manufactures under the BD name. Whether or not this pump system is built by someone else is something I cant answer.
aFe also makes a fuel pump system with a completely different polycarbonate sight glass which is really kinda cool. But its rare that you hear of anyone running these pumps. Maybe because they're so expensive...

Other than that, I cant think of any other fuel pump systems out there which are plug and play...or mount and play. There are plenty of DIY systems out there people build themselves through various parts and configurations but most members run a tried and true system. Are there problems?...heck ya, but thats the whole point of a forum. My suggestion is to do an internet search about the specific fuel pumps you're looking at and see what Google comes up with. There will likely be numerous forums threads/posts about the very topic you're curious about.
The only thing I will add to this is that you absolutely need a fuel pressure gauge...!

I think I have about 50k on my fass and it works great. If I remember correctly, it has a lifetime warranty, does it not ?

My fass is three years old now and no problems. It came with a four year warranty.

Installed a FASS DDRP about two years ago and no problems. Simple to install with no modifications! It came with a four year warranty at the time.

Thanks for the replies guys. Are you all running the fass pump on the side of the engine? Is anyone using the kit and putting it on the frame?

 

[EricViviano]

The afe pump looks really interesting. Much more compact than the traditional fass or airdog frame mounted setup. But it still has the added filtration and aeration benefits. Going to do some more research on it.

Currently FASS DDRP is mounted in stock location for a stock engine etc. Considering relocating to the frame when replacing/upgrading the fuel supply and return lines at some point in the near future. Trying to keep it simple! KISS method! Used a couple of stock Carter lift pumps for 18 years and it was always turnkey reliable until VP44 failed @ 250K miles and it starts and runs turnkey as before with the FASS DDRP mounted on the side of the engine.

The AFE pump does look interesting, but I have not seen one in operation. I have seen good results with the the current AirDog Raptor 100 FRRP stock/engine mounted lift pump too!
As mentioned, you are going to get a lot of opinions and experiences. After you do some research and reading you will most likely find the choice that makes the most sense to you.
Enjoy the research and looking forward to hearing what you decide to install in your truck.

Well, you made me look it up. But my titanium series fass does have a lifetime warranty.

 

[Chief USA]

Still have the original Air Dog 150 on my truck. Its been on there for about 12 years I believe and it has worked flawlessly. (Knock on wood, don't want to jinx it ) I use the Fleetguard filters on it. If I remember correctly it has a lifetime warranty. I will have to double check that though.

321,000 miles on truck with 70,000 miles logged on a used Fass lift pump (95 GHP or less, I think) that I mounted on the frame rail in April of 2016. I did not change line size and I still use the factory fuel filter. I added a 40 micron screen between the tank and the inlet of the Fass lift pump. I used a $7.00 oil pressure switch with a snubber to monitor an LED warning lamp on the dash for low fuel pressure.

I also have run a Smarty S03 programmer on a mild tune for the last 70,000 miles (20,000 of the miles with RV275 injectors). I have had zero issues. I carry a spare used Fass lift pump with me for an easy roadside repair, if necessary. Also, I have logged over 230,000 miles on the replaced VP44 that was covered by dealer warranty.

My fass is in the stock location. I may move it to the frame at some point. It maintains about 18 psi most of the time. I carry a Carter pump as a r emergency spare.

Unless you need a new VP, leave it alone. I recommend an Edge EZ, 10 minute plug and play. Adds 65/180 and comes with a boost fooler and elbow. RV injectors are new Bosch and require no core, for 30-40 hp and 90 torque. I run this combo for 12 years and 220k miles with stock lift pumps and no gauge I do have one now. The combo dyno's 335/800. My stock clutch held up just fine. At 210k miles it was worn completely out. I changed it with a stage one Sachs, slight bump over stock.

I now run an Edge Juice with the same injectors. I started with a DDRP, it lasted 30k miles so I went with a Raptor 100, stock engine mount. When it dies I will go with a Raptor 150. The 100 is not quite enough on level 5. It idles at 18 psi but drops to 8 on WOT. I still run the stock oem turbo and VP, 330k miles.

If you don't have gauges....you need boost, pyro and fuel pressure. Then when you get it all powered up, get an exhaust brake to help slow it down. Sometimes I use mine uphill, when a new 4th gen gets in my way J/K.

@NIsaacs Do you have a link to those RV injectors? Haven't seen them before. Thanks.

You just have to look for any places who has them for sale... Sometimes they sell them without the cores and sometimes they want the cores. Because the RV275 is (should be) a brand new injector they shouldnt need the core. It just depends on who has them for sale. I happen to get mine from a member who had them and never used them.

Most internet diesel parts stores will have them, price varies a little. This link is to Geno's.
