Leaking clutch fluid

Hi guys,

Quick question:

After having my transmission out, my clutch pedal is seriously soft and does not disengage the transmission properly.
A quick investigation revealed a puddle of brake(clutch) fluid under the car. when the pedal is pressed, fluid runs out from what appears to be a valve (the black thingie in the picture) in the rear clutch pipe.

So I have 2 questions:

1: Is this fixable without replacing the pipe and the valve? (Not the end of the world to replace: https://deroure.com/partinfo.asp?MAK...=0&PBID=244948)

2: Seeing as I have spilled a fair amount of fluid onto the floor, I need to at least top it up, and if I replace the pipe it will need to be bled. Where is the reservoir? From the parts schematics it looks like it shares a reservoir with the brake master cylinder?

Understeer is when you hit the wall front first.
Oversteer is when you hit the wall rear first.
Horsepower is how fast you go when you hit the wall.
Torque is how far you take the wall with you.

Correct; the brake and clutch system share the same reservoir

Clutch delay valve appears to be leaking..... unless you like using "launch control" or otherwise like doing standing-starts by dumping your clutch, replace that with the factory standard Clutch Pipe ... Lotus part # C120Q0003F

Thank you all.

I ordered a replacement pipe.

Yeah it looks like it is one assembly to me. You could alternatively buy a replacement from BOE if they are hard to get. You will need to bleed the clutch system after, but it's really not that hard. It does share a reservoir with the brake fluid, but you cant run the brake fluid dry from a leaky clutch.

Since is shares the reservior with the brakes, I can just use my everyday bleeder tool kit (https://www.eliseparts.com/products/...tch-bleed-kit/)

I just need the new pipe to get here. Not that I am in that much of a rush, the car will not come out of winter hibernation until April.
