On several MB’s that I have owned, (but different chassis) I found areas of wear from rubbing, or the beginning of degradation & cracking on those fuel cooler hoses. You do not want to have them leak or come apart on you - spraying gasoline onto the exhaust manifold isn’t exactly an ideal situation.
May I suggest that you take the old hoses to a hydraulic line shop, where you can have them use the original fittings & replace the hose sections. I did this for both my 107’s – it was cheaper to have all three hoses done with braided stainless hose versus the cost of 1 single new hose.
