Fuel Preporator Users?

[R.E. Miller]

Does anyone run one of these systems on their big rig, tractor, boat or 5. 9L? I was reading their ad on etrucking and was wondering if any TDR guys were running these. If so what do they cost? They claim 6-14% better MPG and 20-35 HP increase Sounds neat and the whole idea is to reduce entrained air and vapor out of the fuel. Check it out

Thanks guys,

I checked into them once and although I can't remember the exact price I do remember it was way too much. In fact when I saw the price I quit reading, that's probably why it isn't on their website.

Chip at Blue Chip Diesel has one on his truck, you might give him a call. As I remember he did a neat little experiment where he could switch back and forth between the stock and the fuel prep. His results were quite interesting.



I would really like one of these, but the price tag is up there (~$700 if I remember correctly) I spoke with Brad (I am gonna murder the spelling of his last name) Exstam about these. Sounds like an excellent product an innovation, only if the price was less



A friend of mine who is an OTR trucker said that these thing are great on a big truck. They very easily pay for themselves in fuel economy saving alone (it adds up pretty quickly when you drive over 100k miles a year and get less than 10 MPG), not to mention the little extra HP for pulling the big hills.



Brad mentioned that the motor will start much easier in cold weather too. Said something about a school district buying a bunch of them because they needed/wanted the busses to start easier in the winter.



Let us know if you end up with one. I'd really like to hear some more real world expereinces with one.

OK, you have brought up a subject that I have been thinking about for a couple of years. I propose that if a person puts a pusher pump back by the tank that puts out more pressure that the normal lift pump. Somewhere in the fuel line between the two pumps a person installs a vertical "cylinder" with an inlet high, outlet low and a "pop off valve" in the top hooked up to the return line. The end result should be "something" like the preperator that is mentioned on this thread.



Maybe some of those who have installed pusher pumps already will chime in and let me know where my theory falls apart.

 

[R.E. Miller]

I am going to look into this thing, might try to save up If it does infact do what they say it might really be worth the investment if you are going to keep your truck for the long haul like I plan to. Products like this are surely not for people who rotate their vehicles frequently, unless they have lots of money in which case none of this statement matters

Thanks for the info!

Call Enterprise Engine

Russell,



I think Enterprise Engine has a "kit" for installing the FP on Dodge Cummins trucks, wouldn't hurt to give them a call. I would get one if I had the extra cash, it is on my list of things to get, need to get an E brake and real exhaust first.

I almost positive you can get an install "kit" when you order the fuel prep. The kit included new fuel lines and, if I remember correctly, it was $50.

 

[Dennis Garrett]

As expensive as they are new, I wonder if you could find one at a trcuk salvage yard. If you dodn't have much in it to start with, you would feel a little bettrer about if it didn't give you the results you expected.

Fuel Preporator

We tried them on a fleet in Texas (30,000,000 mi/yr. fleet) and they did work, however maintenance ate up savings. Mechanic had to flush out unit with citric acid at about 20k miles. The rinse was clasified as hazardous waste, creating another set of problems and costs. For an owner operator, doing most of his own PM, the % fuel savings could be worth while. These are made for large engines, at 7-8 mpg, and it would take well over 100k miles per year to be cost effective. I put one on my '90 6. 5 Suburban (free) and picked up about 0. 75 mpg, but it still had to be serviced, never did put it on my '94 5. 9 when I traded.

I Have One

Still haven't installed it. Brad told me it would fit under my 2wd but only if I fit some shopping cart wheels under it. It's like 17" tall!!!



BTW, there are not dyno charts to verify the power claims. Or at least not at the time I last spoke to Brad Eckstam.



I do have dyno results from my truck after I installed my upgraded fuel system. I can claim a 36 hp improvement.



Still I am interested in the FP. I have one in the shop and it was near 1 large $. At this point I may mount it in the bed for testing. Mounting the thing in the bed is not a good option for most unfortunately.

I too am interested, but not enough to shell out the dough. I think puting a pusher pump in the tank may get rid of many of the problems that this unit says it soves... .

 

[Cooker]

Pusher pumps may really help you 24v guys, but us 12v guys are in a little different boat. I think Ted J. was working on a revamped fuel system for the 12v (in addition to his 1/2" fuel line kit).

I have a fuel preportor on my '98. 5 truck, it fits and works great. Tucked it up within a quarter inch of the bed and used the shorter fuel filter. A longbed would make the install easier. I don't track fuel mileage well enough to comment but the larger fuel line and pusher pump pressure did increase horsepower and midrange throttle response. Fuel pressure only drops a couple lbs. at WOT. I appreciate having the water separator and large capacity fuel filter at the tank.
