Im gonna be ordering one of these fuel systems here soon and wanna know the pros and cons of both these systems, who like what about them? Talk me into one or the other!!

Thanks fellas

I'm finishing putting in my fuel boss today. One of the reasons I got it (instead of Walbo electric or FASS) was because of the seperate (but still functional) 'drawstraws'. The stock electric still works when pressure drops (like start up) and also I don't have to worry about not having the use of the last 1/4 or 1/8th tank of diesel because the level of diesel is below the new draw straw (which apparently can't be fixed because of the 'molded' in feature of the OEM fuel pump pickup)
I guess you can't use a Fluiddamper harmonic balancer with the Fuel Boss (but I've had my doubts of the usefulness of a improved harmonic balancer at a max of 3200 RPM's and Cummins engine life of 200,000 or 300,000 plus miles)

 

How does the Fuel Boss fix the low fuel issue? It uses the same pickup as the walbro kit...does the hobbs switch automatically switch to the stock pump when it cant get fuel from the gdp pickup tube? or are you planning on setting up the switch so you can manually switch between the fuel boss and the stock pump? (which can also be dont with the walbro)??

I've been struggling with the decision for a while, so definately interested in thoughts / more info.

 

Yes, when the Hobbs switch senses a pressure drop (either due to start up lack of pressure or the level of diesel drropping below the new drawstraw) it turns the stock elec. fuel pump on.
I didn't think before writing "instead of Walbro or FASS", you are entirely right, it could be set up the same way with those systems
I haven't seen the MitUSA pump, but the GDP seems very well constructed IMHO, and GDP (actually Richard) answers the phone (and the one time I had to leave a message at lunch, he called right back in like 20 minutes!) and everything I've gotton from GDP has been very complete regarding parts even nut's and bolts and wiring and connectors etc. (well they didn't include the crimping plyers ) LOL!

 

I have been looking at these two kits myself and wondering which one to get. So far from reading dtr and researching on glaciers web site, I think I am going with the fuel boss. Yah you might not be able to use a fluid damper but I dont really care about that anyway. But the fuel boss does use the stock lift pump for start up and then swaps to the fuel boss afterwards on its own. and also if the draw straw of the fuel boss cant pick up fuel due to low levels it will switch to the stock lift pump. I think you can read more on this in the installation instructions on glaciers website. I believe that is where I read it at. let me know what you decide.

 

I wonder if the engine would stutter, or miss before the Hobbs switch could senses low fuel pressure, engage the factory electric pump, and then finally build up fuel pressure again?? Surely someone must have one setup that could clarify.

 

I like the Mitusa pump kit

 

I read the GDP Fuel Boss install manual, that's what got me confused...because there's a section that talks about wiring a switch that allows manual selection of stock vs. fuel boss......if the hobbs is automatic (for start and low fuel), i'm not sure why you'd want a switch....???

I like the fuel boss better on principal...fp rises in lieu of lowers....but i'm dependant upon taking my truck to the dealer for basic service, and i could just see the moron's tightening the belts (w/o noticing the fuel boss) and over tensioning the belt and causing issues....with the electric, the monkeys can really hurt anything as it's not part of any service routine, nor connected to anything that is....

For anyone that works at a dealer, i'm sorry to be so harsh, i just dont have a respect for the service depts based upon my experiences with 3 dodge's over the last 15 years.

 

I run the Mitusa and have found it to be of super quality. There are two Mitusa pumps, by the way. I believe Opie said the smaller unit is good to 700hp and the lvl 2 is whatever you got. These mechanical pumps are great as they deliver depending on what your engine need is. All the support fixtures are of highest quality. I don't worry about fuel delivery any longer. Money well spent.

 

So dose the Mitusa work the same as the Fuel Boss as far as the hobb's switch? Like at start up uses the stock lift pump and then switches over? Thought i read some where that the Mitusa comes with the incab switch?

 

is there a link or web site I can go to read about the mitusa lift pump?

 

mm73 go to http://www.TNT-Power.com there is some info there but very little!

 

Also try here http://www.Opieparts.com. Just cant find much info on this system.

 

I would buy opies just for the fact that it can be used with a fluid damper

 

The standard Mitusa can not be used with a Fluid Damper. It uses a hobbs switch set at around 10 lbs to start and stop the factory lift pump, uses 3/8" lines, a regulator, a check valve and billet aluminum filter cap with a fuel fitting in the top. From the filter to the cp3 is stock. It is all automatic, you start or prime the system (during filter change) with your factory lift pump then once the press reaches 10 psi it shuts off and runs off the mitusa. I also have trucks that have lost the factory lift pump and we installed the mitusa and the truck starts and runs fine with just the mitusa. I have no knowledge of the fuel boss but it looks to be a exact copy of the mitusa. We usually have the mitusa in stock and if you have any questions let me know. Tim
