Routing of drain tube from brake fluid reservoir

Post by inaglasshouse »

Hi all,
A '70 911 has a transparent tube attached to the brake fluid reservoir, to act as a drain.
Question is: where should the drain exit the car? Having looked at many photos, the tube seems to meander down the front wing toward the front of the car, somewhere near the windscreen washer bottle, but I can't see where it exits.
Many thanks in advance for any help.
Cheers, Richard.

It exits by the front of the bumper, on the nearside. If you look under the car forward of the petrol tank, and where the bonnet slam is, you will see a hole it ‘pokes’ through to exit under the car.

Thanks for the reply, much appreciated.

Do you mean one of the four holes (approx 25mm diameter) in the vertical section of the front panel, which are used to access the front bumper retaining bolts? Like the one shown in the attached pic, but a nearside one? I thought those were all plugged with plastic plugs? Other than that, I'm a bit low on holes...

.

I never liked the idea of 'dumping' excess brake fluid to the outside - to be blown onto underside of the car (or the front of a following car) - so in my early 911's I always routed the hose to a small 'catch tank' sited in the smuggler's box ...
