Since I have mounted the brake master cylinder under the dash on the 32 I have had tmake a remote filler as the orginal one was plastic I had a oil fill cap I ordered that didn't fit so I got a mate to thread a bit of stainless to suit Once I got that I found a s**** bit of stainless pipe cut it in half and tigged on some sides then lots of drilling and fileing later I had a top and a bottom The pipes out the back were cut from a music stand at work the bolts are welded in from the inside so the whole thing mounts to the firewall with no fastenings showing A quick polish and it looks like a storebought item I have to drill a descret hole soewhere as it is airtight something I never thought of till I posted progress on this item and someone mentioned it
you could drill a 16th inch hole in the side of the cap and a 1/8 in the center conecting to the side hole and you will never see it or worry about fluid leaking out.
Yeah thanks for that I was thinking of a small hole in the side of the cab and trying to intersect it from the underneath I doubt the fluid will leak out as long as I am the right way up that is
