I had been awaiting a peek behind the fuel tank with bated breath. I was curious, hopeful, a bit intimidated, and the realist in me was asking, "how many ways is this car going to break my heart today?" I grabbed the creeper and a couple drop lights, took a deep breath, and dove in! We'll start with the 'good' side, and by good, I mean the driver's side with a brake hard line that wasn't yet gushing fluid. Yarp....doesn't look so 'good' after all.
Let's just do a little poking around to see how bad it is. I mean, I see a hole...gotta poke at it a bit and check, right? Yup. there are some structural deficiencies in this area that aren't going to be repaired with Bondo!
Now that we've gotten the 'good' side out of the way, let's hop over the passenger's side, aka the side that leaked brake fluid and required all this disassembly. Hmmm...interesting....not great, but not holes surrounded by rusty sheet metal with the consistency of tissue paper, for what that is worth. I still can't tell exactly where the brake line failure occured, but safe to say that I am glad I tore all this apart and made plans to fix and replace it.
If we just pan up a little bit to the underside of the cubby behind the passengers, we can see the access hole for the pump and sender and bright, shiny, nearly-pristine sheet metal! Let's all take a moment to recognize the sacrifices the fuel tank made to save the chassis in this area...
Panning over just slightly, here is a great view of the one puzzling area that Suzuki deemed worthy of seam sealer. So strange...if this is the only seam at the back to get it, why even bother? The problem brake line is clearly visible in both the shot below and the one above, and although it looks like it isn't all that far above the fuel tank mounting points aligned with and just below the brake line clips, I can assure you that trying to loosen the fuel tank in place, remove the front two mounts, and sneak the line out past the tank would have been a fool's errand.
Here's the non-leaky-side brake hard line out of the car. Looks like it is about six inches from the grave. I'm glad I removed it, but at this point I looked at the shape of the line, had a bad feeling, and started digging through the parts I had bought from Japan so far. Sure enough, nothing to match this line! However, the shape rang a bell, and I ordered and received this line along with the others, but somehow my brain decided it was for the front near the master cylinder, and I tried a dozen different ways of matching it up to the existing lines and failed, so my brain then decided that I must have accidentally ordered the line for an ABS car, and sold it! Doh! I could have cross-referenced part numbers, but I didn't. I could have been more organized when ordering and receiving parts, and labeled the bits as I pulled them from the long-awaited box from Japan, but I didn't. Lesson learned; you can't be too organized when undergoing a partial restoration, or whatever this project is. Take notes, double check, make copious labels, store parts carefully, and when in doubt, hang on to stuff! I got a second one of these lines on order.
Here's the 'bad' side, the one that peed DOT fluid all over my shopmate's trailer when loading the car. Still not completely sure where the leak is, but I think the failure point is the damp spot just below the ugly cutoff-wheel mark in the vice.
