What's the scoop on the RASP fuel pump? Any info, pictures, feedback on this?

Thanks

Thanks for the info. Are there any pictures of an installed system available?

 

[BTarbert]

Anyone tried this yet?

 

[JR2]

There has got to be more info/photos etc out there.

My understanding is it has only been available to the public for a couple of weeks although they have had several installed for about 6 months. I am sure the pictures will be out soon I did check it out at mass diesel this morning and it is a very good looking product the craftsmanship is excellent as I said in my previous post I have talked to DTT about it and then with Scott today I will be buying one soon.

I saw the setup in person @ Muncie.



It's beyond beefy and looks to be a very well engineered piece. I'm glad it is finally making it to the public...

I am sorry I have dropped the ball on this information. I have had some serious problems with my race car engine that has occupied way too much of my time. So I will be taking this weekend off to get my information together for you guys. I'm sure K. O. isn't very happy with me either.



This is the ultimate system, and soon you will all see why I say this. If any of you have any specific questions please feel free to ask. I often check the site, and so that way you don't have to wait on information that I can answer right away.

where can this be obtained from? sounds nifty. I like the idea of keeping the stock stuff

 

[massdiesel]

DTT

DTT is the supplier of them. Any Dtt dealer should have one in stock. We can be of help to you here with one just call 508 660 7093

any idea on price?

 

[massdiesel]

Sorry

not allowed to post prices

 

[DOUGMartin]

Ok I got a pm on price. This sytem seems to be ABOUT the same price as some of the other systems that are electric. Im not trying to start anything here but can any one tell me why I should spend my money on this system as oposed to the other ones. Thanks Doug.

• It's mechanical - compare the failure rates and MTBF between mechanical and electric pumps - the choice is clear.
  
• Redundancy - This system allows you to run your OEM or aftermarket electric lift pump in parallel - the mechanical pump does 99. 95% of the work, but if something happens - the electric pump setup will get you home.

In addition, the mechanical pump speed varies with the engine rpm. The higher the engine rpm, the more volume the pump produces. This more closely follows the engines demand for fuel. I like having 14psi when I launch, and 14psi through the lights! Of course now, I keep forgetting to look, because it's no longer a problem, unlike with the stock lift pump. On a good day I would be less then 5psi through the lights, with the stock pump.

ON the other hand, SOME of us using our trucks in RV towing often find ourselves down around 1800 rpm pulling a heavy load up a steep grade with a Comp on 5x5... Might not be a factor, but I sorta like my fuel delivery operating at a constant, REGARDLESS of speed or load - maybe not important as long as even the MINIMUM values are met...



We're not ALL dragracers!

Will it work on the '03 and up trucks?

That's why I said 14psi at launch. It does meet not just the minimum, but recommended psi, at idle. With plenty of volume to spare. This system has a bypass valve, that allows it to maintain a constant pressure. The pressure doesn't vary with rpm, just the available volume. Sorry I wasn't clear in my first post.

mberry... the truck at Muncie with the system installed was a 3rd generation truck.
