Hose Question

[karlfranz]

I had to replace the hose that goes between the filler neck on the plastic header tank and the turbo because the older one started leaking. This is a strange hose though because it has a different inner diameter at each end. The fitting at the turbo end is smaller than that on the header tank. I also notice that the OEM hose is stamped Aramid throughout its length.

I had to improvise a new hose using two different I.D. hoses and an adapter to connect them. However, the smaller (turbo end) hose is actually fuel line instead of heater hose because the auto parts store does not carry heater hose with that I.D.

My concern is whether it is acceptable to use this kind of hose until I replace it with an original hose. I know the turbo gets glowing hot and I don't know how heat-resistant the fuel line is. I would expect that the Aramid hose would be flame retardant. Although the hose itself doesn't touch the turbo, it does travel rather close to it. I don't want the hose to burst from the heat and have it pour coolant over a hot turbo.

Expert opinions welcome.

KarlFranz,

I would get a piece of slightly larger hose several inches long, split it lengthwise and place it over the 'fuel line' hose where it comes close to the hot spots to act a an insulator, maybe even a sacrificial one. You might even consider wrapping a bit of aluminum foil over the inner hose first as additional heat insulation. Should work fine. Happy Motoring! ...Jim'85TE
