87 S4 High Pressure Fuel Hose Replacement - What do I need?
#16
When dremeling through the collars, its easiest to do if you make a single cut at 45-degrees to the direction the hose runs (i.e. 45 degree angle from the edge of the swage up to the mouth of it). Stop just before you cut through, and then when you open up the cut with pliers, the last little bit will snap apart and you can take it off without risking scoring or cutting the metal hose fitting.
You really do not want to damage the metal barbed fitting, as it'll risk fuel leaks.
The only two hoses available from Porsch still are the front one between the rails, and the S-shaped one.

The one from the cooler to the "console" coupler is 928 356 081 04 and still available, $37 US according to Roger so I have both on the way. We'll see
So, hopefully be done with this shortly. Thanks again for all the help.

I read these fuel hose posts with fascination, topped with a bit of dread. I need to look at mine.
Is there a step-by-step process Dwayne-style for this procedure? This is not an area where I want to miss a step or do something wrong.

Piece by piece is probably the best approach. Depressurize the fuel system, unplug the battery and start going through each section. I chose Roger's kit and posted it on the RW last year. I found a badly worn return section and am really glad to have this kit and now piece of mind.

More drama on this. Roger set me up with what we thought was the right hose, from the "console" to the fuel cooler; 928.356.081.04.
Slight problem though, the connection to the fuel cooler is different on my car than on this new hose.
The new hose is show, I am holding the fuel cooler end of my existing hose.
Oops Roger is looking to see if there is another hose, more after that. As far as just replacing the rubber section I can't do that, the hardline of my old hose is damaged where it meets the rubber.
I'm in real trouble here We'll see how this plays out......

The hose pictured above changes between '87 and '88 model years.
PET shows 928 110 640 01 bracket and 928 110 359 04 hose for the '87 MY
928 110 359 08 fuel line return..........'88 MY
I'm sure Roger will sort it out

So, if someone comes along later and sees this, there is a difference not just from 87 to 88 but from early 87 to late 87.

I can say I am really happy I replaced my fuel lines. Roger's kit was very nice. Some people might think, "I paid $XX just for that?" until they have an fuel line related fire and then think, "I could have just paid $XX and not had a fire!"
