How do I stop the leak?

[Marty G Cars]

Just had the valves adjusted this afternoon on my new 427 and wanted to go on my first true ride and now the pressure line from the Hydra Boost to the PS pump is leaking (big time) where it attaches to the hard line at the pump.

When I try to tighten the fitting it just starts to twist the whole line because there is not a nut or anything to hold the hard line while tightening the braided line.

can you run a solid braided line with an's on both ends

If you use braided line, it has to be nylon sleeved line 2500PSI line, and what a PIA it is to build. Finger *****s a plenty. Expensive too!

I'm confused, which is normal for me. You state " When I try to tighten the fitting it just starts to twist the whole line because there is not a nut or anything to hold the hard line while tightening the braided line."

Is there a short hard line, then a flare on the end of the pipe to attach the flexible hose? I'm just not clear about your assemblycomponents and exactly where the leak is.

Frank, I believe you meant Teflon lined. Besides the dedicated fabric-covered PS hose by Aeroquip and Earls, the Teflon lined hose is the only user-serviceable hose available.

Compared to standard AN hose (fuel, water, etc.) Teflon is almost the same price by the time you get done with the fittings, and assembles a whole bunch easier.

The leak is where the braided line attaches to the haed line shown in the pics. The braided line came with the Hydra Boost and the hard line was from DSE as part of my Front Runner package.

You must be using the wrong place... I get that stuff for 3 bucks a foot or less!

I don't know how to tighten that fitting without damaging the hardline. Does DSE have any suggestions? Are the fittings on both ends compatible?

[Matt@RFR]

(Snip) Are the fittings on both ends compatible?
That's what I would ask too. You sure the hard line has a 37º flare?

My memory is shared with Carl's.

Isn't this the line you have to assemble with the DSE parts? I did it and it's fine. Maybe there's an assembly error?

Hey! That's not how this story is supposed to go! Ok, ok, nobody is immune from Murphy's Law it seems (atleast you aren't having a problem with a hose end that we pre-assembled for you) (!). :spank2:

BTW - here is an illustration of the DSE extension tube assembly: http://www.detroitspeed.com/Hardline10.html

From what I have seen, the DSE extension tube assembly has an end on it that mimics the Aeroquip hose end male nipple / threaded interface, which means that the Aeroquip TFE AN-6 hose that we supply is perfectly compatible. (it sounds like something just went sideways during the assembly procedure, which a quick re-do should clean up without to much hassle).

Frank - here in house, we laughably call getting zapped by the hose "getting snake bit" - I will occasionally hear one of the guys cussing, hissing and spitting througout the day because he wasn't paying attention while assembling the lines! Amazing how much a few little pokes in your finger tip can bleed... Be carefull!

Paul, it's kinda hard to see in his origininal pics, but shouldn't there be a fixed hex on the hose end and a nut/rotating hex on the tube? Tighten the nut on the hard tube while using a backup wrench on the hose?

As previously acknowledged on this site, Paul has come through as THE MAN. I left a voice mail at Hydratech yesterday explainding my problem. Then to my surprise, I get a call back from Paul TODAY (he was working on Saturday trying to catch up on a few things and thought he'd see who was on the voice mail). He told me over the phone basically how to rebuild the end of the (field rebuildable) braided hose fitting in an attempt to fix the leak. After about 30 minutes of work I had the hose removed, rebuilt and re-installed.
LEAK IS GONE!

The only damage was a few jabs of braided hose barbs in the ends of my fingers and a couple of burns from touching the headers. The results were well worth the costs.

Thank you Paul!
