After testing the tank with compresed air I found 3 leaks around the welds which were promptly re-welded to seal them up. Had a problem with sealing the sender/pump assembly ....leaking where the bolts were fitted ....was going to use o rings on the outside but will probably use them from inside the tank, that way I will only need to use one per bolt. so I will be screwing the bolts upwards from inside of the tank then putting shakies (spring washer) on with a nut
Will be picking up my propshaft from Major and Aspinal at Durham.....cost is £100
which I thought was a bit steep considering I supplied the 2 uj's, ah well.
