Lift Pumps

[SmokeShow]

I know this has been beat to death but I'm still a little lost. Ok, these are definately my next mod. and I thought I had it all figured out on going with the 1792 but now I'm just not sure.

My other two of interest are the MITUSA and the KD pumps. Both are about the same cost and supposed to be the cream of the drop. What are y'alls thoughts on those two? The prices are high but if they are that much more superior (meaning they will last MUCH longer and perform well) then I'll consider it.

Well, I just got the 1792, and it gets me the extra fuel in addition to the dual cp3s that I need, but you can here it in the cab.

I am getting a MITUSA, when I have the $$$

 

[SmokeShow]

Thats kinda what I was digging for here, whats y'alls take on the MITUSA. I can see some of its benefits and it'll obviously supply enough fuel BUT I think one of their selling points is the ability to supply the fuel at XX or even XXXpsi. Am I wrong in my understanding that increased pressure at the low side of the CP3 doesn't really do much extra for you in the way of output on the high side?

I'm going 1792. If it's good enough for Casper, then it's good enough for me.

My next choice would be Super Diesel's setup. All the others are just way too expensive for what they do.

The kennedy everything kit is not cheap, but it does work well. The installation is very clean and comes with a lot of nice features. One of saftey is the oil pressure sensor that will not let the pumps run unless the motor is running. Another nice feature is the underhood pushbutton that allows you to manually activate the pumps for priming the fuel filter after replacement. Other benefits include minimal (if any) restriction to the stock CP3 in the event the lift pumps fail. You can keep on going without need of a bypass valve of some type. The Kennedy pumps also use a unique magnetic coupling design that keeps the pump assembly and the motor assembly seperated so there is less likelyhood of a motor to pump shaft seal leak issue. They also are silent in operation. Mounting brackets, wireing, pickup and installation instrutions are excellent. One thing I'm not sure about the Mitusa, is the belt arrangment and how it may interfer with a future install of twin CP3's?
hope this provides a little more info....

I have dual KD's. The work & they are quiet.

 

[dieselson]

That would be nice. I actually found out the Dual CP3s weren't enough. Adding a lift pump was just right.

Its my understanding that there are methods (being dubbed the Hertz method or Hertz Bracket based on DP member Hertz) that created a bracket that allowes the MITUSA to be used in conjunction with the dual CP3 kits. C.A.P. has it also with his dual CP3s.


Thanks for the replies guys. I'm just having a hard time with "good enough and initial cost saving" versus "long time quality" right now. Just can't make up my mind if I want to pay the price for knowing the pumps are gonna be working and working sufficiently for a good long while or go the "cheap" route with something that I KNOW won't last as long but get the job done nonetheless.

I guess this is just a decision only I can make. We'll just have to see what I decide once I'm ready to pick up the phone and order something.

Is there any gain to be had by the MITUSA 'force feeding' the CP3? It is my understanding that its not possible to force feed the high side of the CP3 via higher line pressures coming into the lower side of the CP3? Anyone care to validate this for me? or else explain how this added pressure from the MITUSA actually DOES give added benefit beyond just keeping the lower side of the CP3 supplied with all the fuel it can pump into the high side.


Thoughts on this? I'm really thinking there is no clear benefit to the MITUSA. It can only do the same thing as a capable elec. pump - supply enough fuel to the lower side of the CP3 so it can in turn, feed the high side of the CP3. So its just a matter of spending money on a reliable elec. setup or spending money on a reliable mech. setup?????

Are these pumps any good? They seem to "fit the bill" nicely and comparable to the Edelbrock 1792 as far as pumping abilities. Main concern is longevity. It says it made to run "full time" so I would think it should have ability to last a while.

Aeromotive SS Series Street Rod Electric Fuel Pump.

A27-11203


For carbureted powerplants making 200-750 HP with standard regulators and up to 1,000 HP with dynamic, bypass style regulators. Ideal for coninuous duty, carbureted applications where more line pressure, flow volume and reliability are desired.

Ideal for your daily driver, street rod or demanding ET-bracket race car. On the street or at the track, you expect durability and reliability, along with consistant high performance. The Street / Strip (SS) Fuel Pump delivers high fuel flow at optimal line pressure. This pump is designed to be used with either a Bypass Regulator; P/N 13301 or one of our Carburetor Adjustable Regulators; P/N 13201 or 13205.




Fuel flow exceeds 900 lbs. per hour @ 13.5 Volts -more than 150 gallons per hour.
Pump provides 18-20 PSI fuel pressure - perfect for high-G leaving cars.
Pumping mechanism features our proprietary composite rotor, stainless steel vanes, and precious ground, heat-treated steel plates.
3/8" NPT ports facilitate easy installation. (not to keen on this detail though since the factory lines are larger)
Alcohol compatible.
Ideal for dedicated nitrous fuel delivery.
Low amperage draw.

Let me know your thoughts.


Thanks

Aeromotive makes some nice parts...I think you'll have a problem running 18-20psi, that'll have to be regulated down to about 12...I wouldn't worry about the 3/8 NPT ports, just get 3/8" pipe to 1/2" hose fittings...That's what I have on the '02...

 

[SmokeShow]

Thanks. I thought they had a good reputation but wanted to verify first. I'll check to see, but seems like those have an adjustable pressure valve.

I learned the hard way running an unregulated Holley Black, not a good idea...

If you're into overkill, this is what I did on my '05...

 

[sweetdiesel]

if i had to do it again i would still go Kennedy quet is right you cant even hear it when your ear is right beside it

i did not get the safety shut down i just wired it keyed hot and put a toggle in between

so i just bought the 2 pumps from him and everything else i got from work

next choice would be the 1792

 

[SmokeShow]

Neens, that looks expensive!

Unfortunately, I have too many irons in the fire right now to splurge on a top notch lift pump setup. I would like to but simply can't at this time. That doesn't take away from the fact that I NEED lift pumps though; hence the reason I'm enquiring about this Aeromotive pump. I have found them to be comparable in price to the 1792 and it is advertised that they are meant to run full-time so they should also last. I was unsuccessful in determining whether or not they have an adjustable pressure regulator on them or if a seperate regulator has to be used.



Right now here are my choices....

Edelbrock 1792
Aeromotive billet SS pump
(2) Holley/ProComp Blacks (the cheapest)
Super Diesel single pump w/o filter (cheap for a kit but not sure its adequate)
DIY Mech. pump (still researching this but its not looking likely)

I'm going thru what you are smokshow.

I'm going to go out and test a new pump that Holley just put on the market. The Holley HP150, it pumps 140 gph @ 7psi, no flow thru though.

My problem now is finding a filter that I like that can flow at least 100 gph. It seems like most of the racor options are below 90 gph. The ones that flow more are way too big to put under the truck. I was wondering if flow rating makes a difference on the filter, and what the flow rating on the stock setup is. Does it even make a difference? Holley also makes an HP 125 that might fit the bill for a bit less money.

 

[SmokeShow]

Where to get one of these Holley HP150's? Seems interesting.

I think I am going to rule out the Aeromotive due to the pressures it can reach. I'd be affraid of blowing through my CAT filter at those kinds of pressures.

I did some digging on mechanical pumps and there are plenty out there to be had at a reasonable price. Only kicker is me not knowing how to route them in the system, etc. I think I could fab up a mount to go where the second alt. can go (like the MITUSA does) but just not sure on where to plumb into the factory system at and not sure what all else I'd need to do (return lines, a bypass, where to get different sized belts, etc.)

This is what I used, 25 gpm....

Thanks Neens, that's what I need and it was right under my nose the whole time.
