Hi all. I'm restoring a Tuscan 2S (cat D write off) and recently had to take the steering rack out to have it reconditioned as it had about 3/4" of play at the steering wheel rim.

However, because I'm a tt, I forgot to make a note of what went were...

I've got the re-con unit back in, but I don't know which pipe into the valve block goes where. There are four connections: two braided pipes that go down to the rack itself - these are fine, as they were refitted by TVR Power's rack peeps. But the other two pipes seem interchangeable. One is a branded pipe that goes to the banjo on the pump, and the other is a larger low pressure rubber pipe (can't remember where it goes until I go and look).

Which one goes to the FRONT connection on the rack's valve block, and which one goes to the BACK connection?

Any help would be most appreciated! Thanks.

Why does yours look so much cleaner than mine? So to speak...

Anyway, here's the offending pipes. This is looking over from the driver's side wing. See those two unions that are half screwed-in? I don't know if that's the right way around or not.



The longer one is for the high-pressure braided pipe, and the shorter one is for the low-pressure rubber pipe. But which goes where? Hey, maybe if I get 'em the wrong way round I'll be on permanent opposite lock, so it won't be all bad....

I would have thought that the threaded fitting would be for the high pressure line, maybe best to have a word with TVR Power as getting them wrong would not be good for the rack.

The threaded fitting is definitely for the high pressure line, but does it go in the back or front hole? Errrr... so to speak, again.... oooeeerrr missus!

I'll talk to TVR Power but that means not getting it all back together this weekend :-(

I'd replace the flexible pipes and fit a Magnefine filter in the return line if you don't want it to fail in the future biggrin

When the metal components wear the fine swarf lodges in the flexible pipes then does a trip round the system from time to time. That's why rebuilt racks fail again in fairly short order....

Just saying what I was told when I had mine rebuilt for the fourth time! biggrin

Just had a look on a tuscan in my workshop for you and you have them the wrong way round. The low pressure pipe to the rear and the banjo bolt to the front. I hope this help's
