Finished all the brazing needed and made a new rubber gasket from some rather expensive Viton rubber, I’m using studs with nylock nuts and washers rather than the mx5 crappy screws which after being fitted and removed 100 times are pretty useless now. These studs are doing the job but they too are starting to show there excessive use so I’ve ordered some M4 12.9 strength allen bolts off ebay for a couple of quid to turn into new studs as I have already broke one of these softer ones and don’t want to be drilling and tapping if another one breaks.
I ground back the welding around all the flanges too to tidy it up a bit, I was also getting contact between some high parts of the welds and the sender unit cover.
I put a couple of gallons of petrol in it last night and had the tank upside down and shook it about this morning after leaving it overnight. No leaks! Woohoo! Just a little chuffed with myself!
No Goo, no JB Weld, no tank sealer or anything just metal rubber and the mazda donor parts. Mission accomplished! Just need to sort out a tethered fuel cap, weld an earth stud on, sort the vapour drain routing, do a little more tidying up and then paint it with the same paint I used on the chassis.
Got the steel delivered the other day as well so I can finish the roll bar this weekend and then I’ll paint that too. :-)
