I would like to replace the 5/16 hose on my 2003 Dodge Dakota Sport 4.7 Engine which goes from intake on back of engine on one end, and the other end goes under the fuse/relay box on driver side. Do you have to remove the fuse/relay box to get at the other end. If so, how do you remove it. Would appreciate any help. I have a Haynes Repair Manual but does not get that specific on this problem.
