Our new customers get a lecture about the need to do ALL the pressure side fuel hoses the first time we do any work in the engine compartment, unless they know (or it's completely obvious) that they've been replaced in the not-to-distant past.

We take the whole rail off and clamp the injectors in a vise (rubber jaw guards are a good idea). We've gotten good at clipping the ring off at the injector with a pair of dikes. We use a large, sharp knife with a big, easy to control handle (little exacto type units make me nervous. We do this job all the time and sooner or later someone would be sure to do major damage to themselves) and slice a strip loose from the injector body back to the end of the barb. When this cut is made correctly the injector hose practically falls of by itself.

We use the OE type German hose (7mm reinforced, smooth finish). Be warned against using the Continental cloth covered hose for FI work - It is NOT pressure rated for this job, even though it is sometimes sold as such.

We use a spritz of "Rubber-Care" from Wurth to aid in installation (it protects the inner surface of the hose from drying out and adhering to the steel, making it easier to remove later, yet it doesn't act as a lubricant for more than the few seconds it takes to do the installation. It penetrates into the material and disappears.

We use double roll-edged (flat clamps cut into the hose) stainless hose clamps on both ends of the new hose. BIG NOTE OF CAUTION: It IS necessary to use clamps on both ends. The original pressed retainer IS NOT REUSABLE. That nice, tough new fuel hose that was so tight going on suddenly becomes quite a bit more pliable under the effects of engine heat and internal pressure.
