Dual Factory Lift Pumps

[TCDiesel]

I have had this install for close to 6 months. . I just thought I would throw this out there to see what the responds would be.



You can run both pumps or switch back and forth. It also has a port for a return line so if you wish you can install a bypass filtration system.



I added the Gasket to hold the O-ring in place. The 1st bracket we did We machine the lip like the factory pump,it begun to leak after some time so we change it too the internal o-ring with placement gasket, it also made it much easier to install. all question and comments are welcome (good or negative).

That is an absolutely awesome idea. If and when this ever becomes a production item, you can sign me right up! While I acknowledge pulling fuel from the stock pump location is not ideal when factoring inpump designs, physics, etc. It is, however, a 'relatively' easy place to get to in order to change the pump. Alongside the road is not where I would want to do this. The built in duality of being able to switch to the 'other' pump is my ideal solution for reliability and redundancy. I have no power mods, therefore would likely never use both concurrently. I am just looking for the best possible reliability. Great job! Wish I had thought of it.

That's a really neat idea! Do you notice any performance/fuel economy differences when running both at the same time vice running just one?

With both Pumps on it starts much faster, about have the cranking time, the truck is highly modified... I could pull the single into Vacuum, with both on it never has dropped below 4psi . When I ran the bypass it pump 2 gallon in 1 minute with both pumps. with just 1 it pump a little under 1. 2 GPM. What I really liked, when it was -33 below here it never drop below 8 psi, previous winters it would drop to 3/4 psi at that temp. . I had to have 10 made it was the same cost as one so (PM). . the line kit is so simple, the quick Dis-connect is the hand style than you use the quick connect fitting on 3/8 fuel line ,1 16. 5 one 3. 5 one 6. 5 and 1 3/8 T/3 brass fitting and clamps.









It is tight. . I installed it at Home in the shop garage W/O hoist. . it will take about 3/4 hrs to install with switch otherwise it's about half that. the most difficult part is the 1st pump and bracket after that it's a piece of cake install.

You could easily install a bypass filtration system to the tank or right back to the other pump. . If someone did this it would be hard press to beat, even the best aftermarket now Do not have one pump filtration to the other. . I have not done this B/C I have one already one on the Auxiliary tank.



On edit corrected the flow from 3 to 2 and 2 to 1. 2.

Thanks for the info and the pics! I've been trying to save some pennies to get a FASS. Something like this has a lot more options that you can't get with a FASS or A/D. The biggest thing is the redundant fuel pump. If one fails, you still have one to run on. The likelyhood of both failing at the same time is slim to none, and slim's on his way out of town. This would be something to seriously consider. Any plans to market this (by itself or in a kit)??

What year truck is this on and would it work on mine? I am two weeks awaynfrom purchasing a pump. I was going to buy the belt driven type. If it will work and the price is right i am very interested but would like to speak to you about it to get some more feedback on the system.

I did something similar to this a while ago and it has been flawless. I added a FASS and used the stock pump as a backup already plumbed in place ready to go. I don't run both at once but can switch over with only a couple ball valves. I don't know if the same is true on the third gens but on the second gen trucks too much pressure (over 20 I think) gives a hard start condition.

TWest, will one of those pumps pull enough fuel through the other if only one is running?

The factory Pumps have a one way valve like system, as soon as it see pressure it will close, so No need pull through, the system will act as one Pump. With cab switch you can run both or one and switch between each one

That is a pretty slick system, especially being able to turn on the pumps in the cab like that. And I thought mine was an easy change!

I guess its not for the in tank guys.

No, it will work for the in tank also, But you will need to install the draw tube and run the feed line to the Pumps. Dis-connect the factory pump hareness than make a harness to run to the Pumps. . the Factory harness are common no Problem their. Genos has the draw tube VULCAN DRAW STRAW V ('05-'09) DODGE-Dodge Cummins and Ford Power Stroke Diesel Truck Accessories - Geno's Garage

I like yours also, the Problem here In MN with the frame mounted units is the winter, the sand, salt, ice chunks, rocks -0 temps and mandatory Bio-Diesel will cause it to fail in short order.

 

[TCDiesel]

WOW,I never realized that the demand would be this big. . So within the next week or so We will put together the standard Plug and Play. . We will also carry the Pumps, wiring,hardware for any custom setup.

Good idea!!!

Do you have a schemtic or layout of the parts involved? parts list? drawing of how it is connected into the stock system?



thanks!
