Anybody out there in turboland know anything about the fuel preporater??? Brad Ekstam of Diesel Performance Products Co. is the person who is behind this device I believe. He is featured in the TDR near the back in #27. I am interested in the devices ability to eliminate vapor bubbles in the fuel. Anyone who has a telephone number please whip it out(the number #ad
). I am concerned about the potential to develop bubbles as the fuel is sucked up to the lift pump.
 
Hey HVAC,

Are you talking about diesel fuel vapors or air entrainment?

Thanks Dart #ad
Tex, I am concerned about the potential for vapor bubbles to develop as a result of the fuel being sucked into the lift pump from the tank. Bubbles are not what I want being sent to the injectors. Hope I have answered your question.
 
HVAC,

Here's my less than $0. 02 worth:

1. This basically has a lift pump - positive displacement pump upstream of filter to allow constant flow . . . this is no advantage over what we have now (unless it is more reliable, pumps more, and allows replacement of the OEM pump).

2. Vapor Elimination - This is what I see as the only slight , if any, benefit, and I'm talking about removing air, not diesel vapor. Diesel vapor cannot exist at 14,000 psi - at this point I'm sure this is a supercritical fluid (no diesel vapor possible) - if your lift pump is operating properly, you shouldn't have any diesel vapor at even the inlet of the injection pump (therefore, we shouldn't have any cavitation in the injector pump). But normal amounts of air entrained in the diesel and even a moderate amount of aeration shouldn't affect the amount of fuel being delivered, etc. because at the pressure we're talking about, the air would be absorbed into the liquid (so little volume taken up by the absorbed air, that I believe you would never see the difference even if it did remove this air).

I read the report from the Univ. of Illinois, and I believe their study was based on a system with no lift pump (this is what I gathered from reading it). This would be like running our trucks with no lift pump - we know that's no good!!! IMHO there's very little benefit for us with this product (but it probably works great on a system that didn't have a lift pump - preventing cavitation being probably the biggest benefit).

If I'm missing something, please feel free to let me know.
 
To throw in my ha'pence, I believe the reason for the 'Preporator' is to, among other things, eliminate the air bubbles that get 'entrained' in the fuel via sloshing in the tank. I think it also removes water, but I'm not sure about that.

Granted, under 14K PSI, air bubbles will be tiny (or non-existent), but think about what happens when those bubbles are emitted from the injector. Also, is 14K PSI enough to liquify N2, CO2 or O2? If so, how fast do they evaporate? What effect do these compunds have on the combustion proces? Any chemists among us?

Were *I* building a balanced, blue-printed, high performance Cummins engine, I would want nothing but diesel fuel being injected into the cylinder. No nitrogen, no water, no carbon dioxide, no oxygen. Just fuel.

Just my ha'pence.

I like this technical stuff, not one mention 'bout mudflaps on this thread #ad


I spoke to Diesel Injection of Pittsburgh today and they do not tout the performance gains of this product (at least not the guy I spoke to). They do feel there is a mileage gain which would entice a OTR truck operator.
I have spoken to Brad today as well and of course he feels there is a performance gain.
He said he has seen a gain on a dyno and he mentioned one customer who picked up 3 pounds of boost.

I need independant verification. The cost being near a grand is causing me to balk.
 
I spoke to Brad again and I am feeling more comfortible with this product now. It turns out this device does the equivilent of what someone mentioned on the fuel starvation topic. It puts a pump at the tank. The lift pumps days work just got a whole lot easier!
He tells me the Fuel Preporater will flow 150 gph. So we aren't just purchasing just a glorified filter.

Next item, this product comes with a new tank to lift pump 1/2" fuel line and a new pick up tube. So now when I start to add the cost of the various components together, I am better able to justify the cost.

Stay tuned, we'll get to the bottom of this #ad
 
Stnadyne makes an interesting filtration system called the Fuel Manager. Among the options for it are a purge pump (also a lift pump), that I believe does the same as the preporator. I did a little unsuccesful searching for this product on the web, as I would like some more info and a price on it.

If I remember correctly, Brad had his truck out at the ralley in St. Louis back in 96. We had the oppotunity to do some tractor pull with some trucks that were provided from Dodge. I ran my own as well as a few others. Somebody ran one that was real strong. Took the sled all the way down, turned around, and brought it back. I think it was the Fuel Preporater truck, but don't hold it to me.

HVAC, can you buy the Fuel Preporater without the 1/2" fuel line, since I already have that? That would save some money.

Hey HVAC, I suggested the pump at the tank. ;p

Several questions to ask:
1. ) Is the stock lift pump removed with this system? If yes great, if no WHY NOT? now you have another restriction, chance for leak, bla,bla,bla.

2. ) What is the outlet size of this device? 1/2" I would hope. Does he include the tubing or hose from the new pump to the filter housing and then on to the injection pump and associated fittings? Yes again great, if no WHY NOT? This would be most beneficial.

3. ) This is a general question for all considering fuel system upgrades. Will the stock filter housing / filter handle the upgrade in fuel flow / pressure?

4. ) Also general. Don't forget about the return line. Restrictions here will also have a degrading effect on the supply side.

Later, Bob

As I understand the system, the stock lift pump is retained. I suppose haveing the pump at the tank, you would just have a more consistant supply to the lift pump and hopefully a more consistant supply to the VP44.

I believe the fuel preporater comes with 1/2" hose to go from the tank to the lift pump. I do not believe it addresses the banjos and the hose from the lift pump to the VP44.

As far as a return, I would hope the old feed line would be used for the new return.
 
Troublemakers!!! I am going to write David_VT in rubber tomorrow.

Don't test me, I am on the edge. At anytime I could explode into a bazillion pieces and cause significant taxpayers fiscal damage as the government attempts to piece together the cause of implosion. You don't want this on your conscience #ad

HVAC, you trying to tell us that you are also feeding fertilizer into that Cummins? Just don't paint the name of some rental truck company on that beast or we all will run like hell... .

============================
With the TDR as big as it is, there is bound to be someone out there who was effected by that blast a few years ago. Please don't be too offended by this sick humor.
