Steel fuel lines to plastic lines

[joe912/62]

Would like to change my 82 steel fuel injection lines with plastic ones. Has a cleaner look. What is required besides the lines? I have a 077 fuel distributor. Do I need banjo bolts at the FD? I have read someone makes a kit.

The banjo bolts on the top of the FD are different for the plastic and steel lines. Search the forum to see if someone else has done this.

The plastic fuel injector lines for SC’s have 12-mm x 1.5 swivel nut/cone nipple for fuel injectors and 8-mm x 1.0 banjo bolt/eye fittings (FD side).

The metal fuel lines for SC’s for SC’s have 12-mm 1.5 swivel nut/cone nipple for fuel injectors and 8-mm x 1.0 swivel nut/cone nipple fittings (FD side).

The metal fuel lines are not using banjo fittings at the FD side. They have 10-mm x 1.0/10-mm x 1.0 adaptors instead of banjo bolts. This is the main difference between these fuel lines aside from being metal instead of plastic.

So Tony it sounds that the plastic hoses could be used if I get the banjo bolts.

As per your request:

These are shorter SC metal fuel lines for cylinders #4-#5-#6 that I use for my CIS bench tester.


A close-up view of the 8-mm x 1.0/8-mm x 1.0 adaptors for ‘81~’83 SC’s.


This is the longer plastic fuel lines for early SC’s for cylinders #1-#2-#3 with banjo eye and bolt.

Joe,

You can buy all the materials you need from BelMetric. And save some $$$ but I would not recommend making your own CIS fuel lines unless you have the expertise to build them. For the extra $$$, you could get them from Len Cummings (BoxsterGT).

If you have a carburetor system that has only 3 psi. for system pressure, making the fuel lines is less demanding. CIS has 65~75 psi. system pressure and could go up as much as 100 psi. in case of a system blockage. It is your car and you could do what ever you want. Stay safe.

I have been sending emails to Len (BoxterGT) with no reply.
Is he still making them.

From another thread... it looks like this is what you want:

Don't recall seeing your inquiries Joe, but the winter has been difficult for me and I am way behind on replies and orders.

I may just have missed your message. Only thing I can say is, keep trying.

This is what I offer for the Polyamide CIS Injector lines....



I also "Re-Make" the original steel 80-83 CIS Main Feed and Return Lines with replacement Polyamide tube....



as well as the 73-79 CIS with just Polyamide tube....



I hope this helps.
