What is this valve above the slave cylinder, and can it be deleted?

Trying to replace oem clutch line with a 1 piece stainless steel clutch line.

 

It's the clutch accumulator. Yes, you can by-pass it if you want.

Here's a run down on it's function:

Accumulators rely on the action of a piston or a valve to delay the delivery of high pressure to a clutch or band. An accumulator works like a shock absorber and cushions the application of servos and disc packs. An accumulator cushions sudden increases in hydraulic pressure by temporarily diverting some of the apply fluid into a parallel circuit or chamber. This allows the pressure to gradually increase and provides for smooth engagement of a brake or clutch

 

Thank you for educating me on that sir.

is it worth installing a stai less steel clutch line?

If so, would you install it to that accumulator or directly to the slave cylinder?

 

I'd keep it and, if you do, there's no reason to change to stainless lines plus it looks like they are all 'hard lines' already...ZERO gain going to stainless lines. Now if you decide to bypass it you likely need to go with a new line and I'd go stainless for that.

 

I appreciate the response again sir, ill just leave the existing line as youve pointed out no benefit to replacing. Thank you

 

The only time you would want to change the lines would be if you are getting rust inside the system (experience from another vehicle - shows up as orangey goo in the fluid).

 

speaking of that, Ive left the line exposed for the pask week since plingnout the engine/transmission, agh, hopefully not too much moisture has gotten in.
