Fuel Line Ferrules

[Paul Hatfield]

I've been fiddling with my fuel pump recently and decided to finally look in my Workshop Manual just to refresh myself with the subject. In the Manual, Section F, Page SF 30, Figure 5, I noticed the ferrules at the fuel pump. I thought they were originally the crimped larger ferrules, but the photo in the manual shows the smaller ones like the ones sold today.
Thoughts? Maybe as Mike Wilson often says: "PORSCHE, consistently inconsistent"
Or, is this a difference in the late C cars from the earlier cars?

That is also a Euro heater spec engine, who knows that may have been just for those engines.

Ferrules were not crimped at the pump nor other places. If the hose is the correct 7,50 inside diameter and the ferrule are the correct size, the hose will stay on quite nicely.

356 hoses were just pushed on to smooth tubing about 5/8". The elasticity of the hose is all that holds the joints, and all that is needed. The metal ferrules only keep the woven covering from fraying, and make the connection look good. The old hoses used to fail at the end. Apparently the stress in the hose accelerated cracking. Hose clamps, a la American practice, seem to accelerate the failure. I think, hope, that the hoses we get today last longer than the old ones did.

I also notice in the photo that the pump shield is being removed. Look at the instructions above the photo- It says:
1. Pull off hoses at pump
2. Remove pump shield.
The photo shows the hand removing the pump shield but the hoses still attached. Step one was skipped.
Kind of funny actually.

Kind of interesting how to get the pump shield off with the rear pan still in place!
