1987 944S Fuel Line Question

[ABigRock]

So I have another one for ya. I just bought this car and have started the long road to restoration. Here is a picture of the fuel line feed and return for my 1987 944S. There appears to be a second filter added to the feed line (correct me if I am wrong here). There is no labeling on the filter. The question I have is can anyone explain to me why there might be a second filter on the feed line and do you think it is alright to put it back to stock? I have verified there is still a filter in the standard location just after the fuel pump.

As always, thank you for the assistance!

My thoughts exactly. The previous owner was too lazy to get under the car and replace the fuel filter correctly. I would get that one out of there ASAP. Every connection and clamp is a fuel fire waiting to happen.

It looks like you can get a nice set of braided lines from Golten who is a member here on PP.

I see lots of AN6 line and fittings on Amazon for around $50-60. Anyone here make their own lines for an S2?

I think what you need is a way to adapt the 16mmx1.5 from the porsche to a 6AN fitting. The cost of those if I remember are at least $10 each and youll need 4. I think when I priced everything out it was near $80-$100 for parts so I just opted to buy lines from Golten.

Even though I would have liked to do it myself, I was worried about missing any specific nuances about compression fitting types and whether the parts I bought were compatible/potentially buying wrong part and having a fuel leak. I read on Arnworx Porsche uses a special globe fitting, which was enough to dissuade me from doing it myself.

My lines from Golten seem to work great - no leaks. Make sure you get the lines for the 16valve motors, as the lines have a threaded connection. The fuel line kits for the 8v cars do not have this threaded connection and require you to cut the line. So make sure you get the correct kit...

I put a kit together with part from several vendors.
I have the fuel rail and adapters to attach to the factory hard lines from Lindsey along with fuel lines, FPR and FPD from Radium Engineering.

I went from this:

My thoughts too so I did reach out for a quote.

Lindsey racing has adapters for that.

Thank you all for the recommendations. I have reached out to Golten for a quote, just waiting to hear back.
