547/3 4 Cam Fan Shroud Fuel Line Junction Help

#1 Post by Nigel Cousins »

Can anybody draw some light for me on what is the correct fuel line junction for a 547/3 4 Cam engine in a 356?

Is it a basic 8mm 'Tee' junction as used on the 547/1 engine or the round junction as on the 692 engine.
Images of both included for reference, any information on when this change is design occurred or supporting images greatly appreciated.

Nigel, AFAIK, all the 4-cam fuel pipe assemblies had the junction shown in your second photo. That soldered junction block must have been a special of some sort but it was also used on all the early fuel line on pushrod engines. I don't know of a ready-made source for the joint. However, to make up your own lines, I would suggest purchase of a used pushrod line to get a junction. Here's one on Ebay https://www.ebay.com/itm/Porsche-356-Ea ... xyuR5TYCdF for $85 BTW, that seller always has those for sale. Photo below is the junction.
