there are plenty of US dealer who can make that hose....but it has to be that parker High pressure line.
I actually called Parker to find out where I can get one made they told me all I needed to know was the fitting sizes and configuration, and they could make me whatever I wanted...the more I looked the more I saw guys who had it saying it was not worth it...so I never bothered

 

Hmmm...I read a bunch of posts where people were calling around and nobody would/could make a line certified up to 30k psi. Isn't that considerably more pressure than any hydraulic system uses?

 

Yes WAY more pressure then a basic hydo system.
Parker is the ONLY (that I found)company that makes them...IIRC its called parker proflex or something.

they are used for water jet cutting is what Parker told me but are still rated for diesel.

 

Yes, I tried that route and nobody could build one, so I bought one. I wouldn't swear I got huge gains, but I don't have any cut out on the big end anymore.

 

No, a hard line made at ahydraulic shop is what i was referring to. I know I did not specify, but that is what I meant.


I am glad it makes sense to you, wish that it did for me. I would HAVE to think the line did not cap off teh return. Especially with that much pressure, there is always going to be fuel that is un-used. To cap it off would be insane.

Two seprate flows? What about on a high HP fuel setup on a V8? It will "Y" before teh fuel rail, and will have 1 line feeding a rail on one side of the motor, and 1 line feeding the other side. Then after the rail, they are joined back up. You have 2 seperate "flows" there, and no problems.

 

here is the thread I was reading.

Most shops still can't make a hard line rate for that use.

Trying to compare our fuel system to a high HP V8 is apples to oranges. A FI gasser system runs what, 40-80psi? That's about 24,920psi less than what we're talking about here.

 

Was not aware of the hard line, thanks for teh tip.


I know it is less pressure but we are still talking about the same principals. Explain it to me then, how does it work (or why does it not)? I mean, if you do not even know whether or not teh return is capped off, how can you possibly know what is happening inside the fuel rail?

 

I guess I could ask you the same question, eh?

One thing I know is that two sources are flowing into the rail and colliding at 25k+ psi. There is no "Y" involved.

EDIT TO ADD: Just went out and looked at my rail. The line replaces the RV. There are no other outlets on the rail so it's basically capped if you install the line.

 

Ask what question?



Huh, ok then. Well, THAT makes more sense with no return. Your theory makes more sense at that point since fuel has nowhere to go. I was under teh impression that there was a return, and that is why it did not make any sense. With no return, where is all the fuel going at part throttle, idle? I can see the "colliding" effect @ the pressures the fuel system is seeing, and for nowhere to go I can see problems. The fuel has to go SOMEWHERE.

 

Eh there tcr, did you have any problems wit yours yet? Some people before on the other page has heard them blow and or cut through the hood. Lets hope not but just askn

 

You guys talk about the pressure of the hydraulics, what about the rock crawlers? Granted the buggie or truck is very lite, but still you would have to turn all 4 say 39" tires from a dead stop and bein wedged in a crevice etc. I would think the hoses to the rams would have to under alot of pressure? Just my opinion.

 

The hydraulic rams on Crawlers are definitely putting out some serious pressure. Not sure if it is in the 25K+PSI range. It maybe though.

 

it's not, it's more like 2000psi max. a full hydro steering does not even come close.
I work on these at work...everything on them is hydro. IIRC they dont even run at 5k psi

And there you have it 53 to the rescue again
