To remedy this problem we bought a 3/4″ aluminum 180 mandrel bend.We sliced the 180 in half to get two 90’s out of it. We also shortened the heater lines to mock up the tubing.Then we simply welded the bends onto the existing heater tubing! Note the weld beads around the end of the tube. This bead keeps the hose from popping off the tube under pressure. You can simply stack some dimes on the end if you don’t have a bead roller.The bends make it really tricky to insert the lines through the firewall (especially once you put the grommet in). We had to twist them all around and do each line one after the other.And Bam! Look at all that clearance.Next, we installed our 2002 BMW brake reservoir relocation kit. This relocation is so common on E30’s that we even managed to find a nice bolt in bracket that allows us to mount the brake reservoir to the OEM airbox mount! This made installation a breeze, and the plumbing was pretty straightforward too.
