replace fuel hoses
so i have the fuel hose kit from Roger and going to my mechanic next week to install, just want to see if there's any "new" warning/idea/advise beside the WYIT to change the heater valve/hose, i am also going to change the fuel filter first so the pressure will be released before the fuel hoses change.
Thanks
Barry

This is what the job entails- if you print it out it
makes it clear what to do.

While the air cleaner box is off, the heater hoses
that go across the fire wall would be worth looking
at along with the short hose from the head to the heater valve.

Those hoses are easy to replace . . . with the expansion valve out and the engine out so you can stand in the engine bay.

I have never seen the heater hoses fail. They are generally soft in all the cars I have seen. Now replacing the hose from the valve to the block with a silicon hose is a must.

I've found many failed rear hoses, they typically go before the early block elbow goes.

Except that the silicone hose will weep the coolant, this is why no one has offered the silicone hoses for our cars up front. It was tested and messy. The 944 guys do it for bling and some of them are now complaining about the mess.

I have never had problem with the silicon hoses I used on the cooling system. They are the same hose the fire department used on their cooling systems. They have been in use for a few years now and never one problem. I figure if they are good enough for the fire department they aught to be good enough for the 928 which is notorious for bad rubber products. Somehow the Germans simply could not get rubber right.

With regards to the silicone hoses turning to mush, that would be more a problem with the pH of the coolant, an incorrect pH (9-10 or high alkalinity) can begin to eat at plastics, rubbers and silicones.
