Hose for Wastegate, '96 HX35

[tomblue01]

1) What kind of hose do I need to replace the one on my half-steel, half-hose wastegate line that runs across my engine from the AFC to the turbo? OD of the steel line is 1/4". Coolant hose? Fuel line? Something else?

2) I've seen many turbos that simply have a short hose from the intake side of the turbo to the wastegate. Do many people modify the setup from the one I have to the above described? Is one better than the other?

3) Why is the hose nearest the AFC so long? Protect the valve covers? [The green dots represent the "unnecessary" length of hose.]

The hose is Cummins part # 3920200 Plain Hose. I believe the extra length over the metal tube is to reduce the possibility of leakage.

Easier to find would be Efi fuel hose it will handle the temp and pressure.

GAmes, thank you for the part #. It looks as if Cummins has superceded it with #3938056. I found a seller who wanted ~$6 for the part and $16 for s&h...
I'll be looking into Bob4x4's suggestion.

I haven't touched the hose yet. I fear it might not reseal well as it has hardened up good. In any case, my search continues for now.

I finally pulled them. Both seem fine. There's an extra long 9" section at the AFC. Just under a 2" section at the wastegate, and it looks like this:

There's no need to loosen up the screw farthest away from the wastegate. Also, I found it easiest to access the wastegate once the wheel well liner had been removed.

Seems I don't have a photo of the longer one, but the inside of it looks just like the one above.

Gates 4219BF Barricade® GreenShield® Fuel Hose seems to be a good replacement, if needed. 5$/ft at the Irish auto parts store. Only need one foot!
