    I just bought a 52 MG TDr VW.  It’s an older Fiberfab kit.  The brakes are almost gone.   Bleeding gets mostly air, but resevoir is near full.   So I’m looking at replacing master cylinder.   However I can not see how to get access between fire wall and cylinder mount under the hood.   The frame is welded.   Removing body panels looks too difficult.   Any help or ideas would be appreciated.

    Thanks

    On my old VW FF TDr, you need to remove the gas tank to get access to the back side of the master cylinder. There should be either clamps or straps (or both, depending on builder) holding the fuel tank down…

    What Kent said and remember to NOT pull the master cylinder bolts out. Slide the master cylinder off the bolts so you don’t lose the spacer between the two front pan pieces. Its a double firewall there where the master cylinder mounts.

    My Fiberfab is has the same setup as Kent’s and Allen’s.  The builder held on the tank with four bolts and large fender washers that he bent the corners of and act like clamps.

    Thanks a lot.   That really helps.   Naturally I just filled the tank. . . . 🙂

    Phillip. When you disconnect the fuel line, have a couple of 5 gallon gas can ready and when the fuel line comes off at the tunnel tube, stick the fuel line in the gas can. Saves gas that way. And you may want to consider mounting a fuel shutoff valve just ahead of the tunnel fuel tube. That’ll eliminate that problem if you ever have to pull the tank again.

    I second the recommendation of putting a shut-off a foot or so downstream of the gas tank. Also means that you can place a fuel filter right after the shutoff and that will make replacing the filter easier.
    I can’t count the number of times I said “well I’ll never have to do that again”.
    Also, it might be possible to access the master cylinder by taking out the battery and battery box. Headstanding will be required, however.

    I’m guessing i won’t be the only one benefiting from these good suggestions.  Thanks again,  guys.

    Don’t know what i did that added the code. . .  I think this tablet I’m using had been dropped too many times

    I doubt it’s your tablet. the editor must have gotten stuck in some funky mode. I removed the funny stuff…. well, if you made a joke, I didn’t remove that 🙂
