MG MGB Technical - Fuel and Brake pipe routing

Can anyone point me in the right direction to some photos of the correct routing of the fuel and brake pipes please?

71 chrome bumper roadster, RHD.

I am sure I can get it wrong very easily, but want to get it right on this new build.

Thanks

Colin

Don't know if this will help but I just googled it and there's lots of pics

Link didn't work for me, try just the end bit i.e. mgb+fuel+and+brake+line+routing

Clausager has pictures although it is of a 64. At some point - probably as the rear harness gained the extra wires for reversing lights, boot light and separate wires to the parking lights each side it became too fat to fit through the four smaller combs, and so was secured by P-clips alongside, but still went through the larger comb at the fixed cross-member. Order inboard to outboard is fuel pipe, battery cable and brake pipe, with the battery cable probably using the inboard of the two available slots once the rear harness was moved away. Another change was on Mk2 cars with the wider tunnel where the inboard stud for the front small comb was lost. A slotted tab was welded to the side of the tunnel and the end of the original strap pushed through that, being secured by one stud on the outboard side.

Paul doesnt the loom go through the 2 grommets in the cross memeber?

Not the later ones, in P-clips alongside, this is a 73.

I have seen some cars - possibly my 1980 Roadster - where the loom does go through the crossmember. My ‘67 doesn’t, though.

Clarification of my second post: The rear harness did continue to go through the fixed crossmember as I said originally, albeit a separate passage, but not through the combs with the other services other than on later cars. Other than the front one pictured earlier the rear harness P-clips on those were attached to the outboard grommet retainer stud.

Thanks Paul, you say not the later ones, when about did they change to P clips?
Colin Parkinson

I don't know, but I suspect it was as the harness gained more wires and got fatter - reversing lights in 67, split parking lights in 1970, boot/load space light in 71, and GT HRW in 71 or 72. For the latter the diagrams indicate that HRWs before that were wired separately as an option.
