I have not seen the slightest tendency for weeping, unlike factory web covered hose that I installed about 18 months ago on a 603 engine. I've always felt that the OE hose leaves something to be desired when it comes to longevity.
I even removed a Viton hose to take out an injector and reused the same hose without cutting it off, I simply pulled hard with needle nose pliers and it came off then I successfully reinstalled it on the injector and it doesn't leak! Don't try that with the OE web-covered hose!  |
Yes, me too. I used the softer viton, 1/8" ID, no clamps. It's been leak-free for a year and a half now running B100. It's a real bear to pop a line off.
