Mitusa Mechanical Lift Pump! It Rocks!!!

[BIG BOB]

In my search for fuel supply, I have researched many different types of fuel systems. My initial thought was to kill 2 birds with one stone, so to speak by going with a PDR cam with a pump lobe on it. This way, I would not only save cost but have the cam for better EGT's, performance and economy, and also have plenty of fuel from a 12V mechanical pump. Problem is, on the 3rd gens, there is no holes for mounting a 12V mechanical pump, 2nd Gens (Willyslover has a PDR Cam and 12V pump on his truck) have the holes but not the 3rd Gens.



I knew I really didn't want to go with an electric pump, eventually brushes would burn out and have to be replaced or the pump would either fail or burn up leaving me stranded. Been there and done that with the White Obsession (my former 99 CTD truck) more times than I can count.



For the last 3 months I have been a Beta Tester for a "NEW" mechanical lift pump for the 2nd and 3rd gens. It Rocks!! I am extremely impressed with this system. I have had no issues at all with it!



First let me tell you what's in the kit.



New cap for fuel filter (because of the pressure and a fuel line runs in the top of it)

All fuel lines and fittings

Mitusa pump with mounting bracket, bolts and belt

adjustable regulator

Fuel shutoff solenoid



This system utilitizes your stock fuel filter and the stock electric lift pump for initial pressure. When fuel pressure reaches 12 or so pounds the fuel solenoid turns your stock electric lift pump off and you are running on the Mitusa. It is designed with a wire to run inside your truck that you can hook a LED light up to, this will light-up when the stock electric lift pump is running and once the system has reached about 12#'s the light goes out. This way, if the Mitusa blows a belt or something the light will come on letting you know that there is a problem, but it will not leave you stranded because you will have your stock electric lift pump to run on.



The fuel lines attach to your standard pickup out of your fuel tank. At this time, the option of replacing the fuel tank pickup has not been developed or talked about. It may be an option in the future. Not exactly sure how the Mitusa will work with the intank pumps, but I sure the developer will have a fix for it in the future!



I am running 20. 5#'s at an idle, I cruise 70 MPH down the highway at 23+#'s and at WOT on 5x5 with the Hot Juice I can only pull it down to 16#'s. My pressures are measured right off the CP3. I also still have the stock banjo bolts except the one on the CP3 where I install my fuel pressure line. I have a mechanical DiProcal fuel pressure gauge.



My understanding is that this system can produce as much as 100 PSI!



This pump has been designed by someone almost everyone knows, for years he has designed and marketed billet shaft for transmissions! Yes it is Opie. He is putting together a dealer network and I'm sure within a short period of time you will get a list of the dealers for you purchasing pleasure! Everyone that knows Opie, knows how meticulous he is in anything he designs. This product is no different! It is an extremely clean mounting system and well thought out.



I highly recommend the Mitusa, I feel this is the answer to our lift pump problems.



I might also mention, he make them for the DuraMax's also!

Wow, Sounds interesting.



We're you saying it runs off its own belt drive? No need to upgrade the camshaft?



Thanks for sharing. .

Sounds like a similar product to the RASP.

Seperate pulley off front of crank. Stock cam, no need to change.

Cool. What steved said. .

Maybe competion will force the prices down to "FASS" levels???

that's the first thought that came to my mind!!!

A picture is worth a 1000 words!

Don't quote me but I think this will be priced to compete with the FASS and Air Dog.



Also talked with Opie today about flow numbers. Open flow (no pressure, this is the way that all electric pumps are rated) is 136 gal per hr. Flow at 100 PSI is 65 gal per hour. He is going to send me the flow numbers with the setup on my truck which is 20. 5 psi at an idle. He also told me he is having the Mitusa Beta Tested on a couple of 1000 HP trucks. He should have some feedback on those truck in a month of so.



He also has the plumbing for the trucks with the intank lift pump figured out. Everything will be available shortly!

I would be interested to see what he come up with for the in tank pump. I would like to know if the pump will pull fuel through the in tank pump when its not running. Have you tried to start your truck with the electric pump unhooked? Thanks Jeff

 

[dcochran]

Mitusa what????

If you want to see a system that looks almost identical check out the following site.

And its been available for quite some time already.

We might have an alternate source for the RASP pump?



However, I (my . 02) think the whole key is the bypass valve right at the VP44 to maintain exact psi regardless of what the VP44 needs are and the state of the electrical system is (cold weather or hot weather).



I think there is more to it than just a mechanical pump.



EDIT:--------



I do not think I made myself clear here. I think the RASP pump is the better choice because, it is more than a pump.



It is a backup system, it is a pump designed specifically for years of flawless running, it is a tested system on our trucks (ask ANY one that has a RASP if he has any failure in any way for anything) for a couple of years and xxxxxx miles, it has a well thought out design that insures the VP44 is properly fed and excess vented back to the tank, it has an automatic failover safety backup (if that should ever happen) that will keep your VP44 ($$$$. $$) alive until you can get to a place to replace the belt, etc, etc, etc.



DTT (BK) can be a really hardnose guy (and he should be in his business) and he saw it and (in post on the DTT site) sent it back for revision several times before he thought it was acceptable to put the DTT stamp of approval on it.



I think you have to consider the whole system, not just a component.

Isn't the 23+# a tad high? Otherwise this does sound pretty good!

 

[BIG BOB]

Opie responded to the following tread about the flow of the Mitusa. He said that at 20. 5 psi, the Mitusa would flow 121 gallons per hour at 2650 rpm's.



Here is the link, look at post #29:

If you go search for MITUSA.com in Google all you get is a bunch of porno sites. Where is the web site?, or is there one?

Rasp!!!

It's a RASP!! Identical to mine. Bought off OPoole off this site. Either they changed the name for some reason or they're cloning it. In fact I think koengineering was part of the initial RASP testing here... been a couple years... but YES IT IS THE BEST.

:-laf :-laf Opie told me he named the pump Mitusa, which means give a women pleasure. I guess it could be worst! :-laf :-laf



I don't think Opie has a website up yet. +

True, but not intirely. The pump is a little different. Opie was involved in the development of the RASP. Not going into details, but Opie definately know all about it and knows what he is doing!

 

[GLASMITHS]

What about the high pressure? Is that good for the VP-44?

 

[BIG BOB]

I asked for mine to be higher that the standard ones Opie is going to market. Then standard one will be set at 16 psi. That will not hurt the VP-44 in any way. I don't think the 20. 5 psi I'm running would hurt it either. Some are running that and more with the VP-44.

Whoa, excellent! This should make for some fun plumbing for those of us who have already plumbed our lift pumps using the vulcan relocation kit.
