I'm converting my 65 to dual circuit using 67 reservoir. I'd lie to see how people have enlarged the hole to fit the 67only reservoir. Thanks!

Would you REALLY need to enlarge the hole???? You'd be running a "tee" anyway from the single reservoir to the duel-inlet master cylinder, why not use an adapter tee and have the first hose be the right size and from the tee go slightly larger to mate up with the dual circuit master cylinder?

Using a Tee with a single chamber reservoir is pointless -- you lose one circuit and you lose both. The 67-only reservoir has 2 chambers and 2 outlets but fits in the same area as the original -- similar shape too, just protrudes out a bit more and needs a larger opening for the 2 pipes that exit the reservoir.
Before I start cutting, it would be helpful to see how and what others have cut.
THanks!

Byas,
The image below is a pic of the backside of my 67 dual MC res. through the rear side of the spare wheel well. Note that there is a little bit of foam insulation. The insulation is factory installed!
Keep in mind that this is from a 67 Type1. Not a 65 Ghia. But being the resourceful man that you are. You'll figure it out.
Good Luck.

Perfect! Thank you. This gives me a better sense of what the original opening looked like and the orientation of the metal tubes that come out of the reservoir. I do have the insulation as well. This portion is identical between the KG and the Beetle.

I've been thinking about getting a dual circuit for my '65, and putting a bus reservoir on top. If it would fit, that is.. then I can use the stock '65 reservoir to feed the dual bus reservoir. Haven't tried any of that yet so it may not even work! But just an idea.

I didn't know that the 1967 was dual circuit reservoir. Never mind !

I added a couple of extra routing pics in my post above for you Byas.
Good Luck.

There have been some odd variations for the '67 that I can't quite remember, including mismatched hose barb sizes, addressed with a weird green hose that had different sized ends, and perhaps other tweaks. There have been threads with photos. But the main think is to use blue brake hose and not regular fuel line, and make sure there are no cracks that can leak fluid out or suck air in. |

Thats exactly what I did on the 63 that we converted. Don't forget that you need a MUCH longer retaining strap. Was glad I remembered that before we painted the car..

I was gonna try that as well.... The ports on the master cylinder for the front brake lines are in the way of the bus lower reservoir....

Why is nothing straightforward???
The metal lines on the 67-only reservoir are 6mm OD. While the elbow on the MC is 8mm. How did the original set up work? The WW repro looks pretty good in quality -- did they just get this part wrong or was the original also like that?

This is what I was hinting at in my post above. A few years ago this was discussed in detail with photos. Search may find that thread and give you answers. |

From the gallery a pic of 1967 hoses. The adapters that are presently available look like they should work.[/img]

| I'm going to put a dual circuit MC in my '57. I'm going to use the stock reservoir for the front circuit and put another reservoir next to the MC for the second circuit. It will still appear to be 'stock'. I'll use Dot 5 fluid (silicone) so I don't have the worries of paint getting damaged in case of spills. |
