My wife's Turbo Esprit has one small problem. There is a vent hose running from one fuel tank to the other. At least I think it is a vent. It runs up below the rear window and then down to the other tank. This appears to be water heater hose and is very stiff. It pulls off the carpet covering it and moves down into view of the side windows. Does anybody have an idea of a fix for this? I was thinking about some light weight PVC type hose for this?
Avoid PVC if it's anywhere near fuel or vapors - much better to use a good fuel line. PVC is guaranteed to harden & crack in record time.
The original vent hose runs above the rear window, not below it. Are we still talking about the same hose? The factory used surgical rubber tubing that was prone to hardening and cracking, which led to a strong gas smell in the car. Simply replace it with fuel line of the same OD. Fuel line is what it should have been in the first place.
The stock vent just lays in the fiberglass groove formed by the window mounting detail, then the carpet is glued over it with contact cement. Personally, I prefer to tack glue the hose at a few points along the run before gluing the carpet. The total vent system was more than that one hose, and all the vent tubing was the same surgical rubber tubing. While you're at it, replace it all with fuel line. There's no magic to it. Just replace the hose.
I did mean OD. The groove in the fiberglass where the vent tube fits doesn't allow for a larger OD tube, and the wall thickness of fuel line is greater than the stock surgical rubber tubing. If you start with the same ID and add a thicker wall, the resulting larger OD won't fit in the groove. The fuel line's slightly smaller ID does result in a tighter fit on the spigots at either end, but the fuel line can be forced on with some effort. It works.
OK. The DPO had already been at work on mine and had fitted quite large diameter tubing. So I just went by ID to fit the existing hardware and somehow managed to make the routing work!
