fuel line for '70 911T

Jeff Jagusch · 04-03-2018, 10:05 AM

It shouldn't be this difficult, but i seem to be struggling finding the proper fuel line to use?

I'm looking to replace my rubber fuel lines on car since it has been in my basement for 8 years. I've measured most of the fittings (fuel tank outlet,fuel pump,T in the engine compartment and the Weber fittings on the carbs I plan to use) all are .312"or 7.92mm

Our hose sells 7mm and 7.5mm ID hose with braided OD

seems to me that 7mm would be too small?

What should I use?
thanks

Jeff

I offer 7.5mm and 9.5mm E-85 rated hose for all Porsche models. For the early 911 models I offer this in bulk along with the correct Factory Norma clamps.

For the later 911 models with the higher pressures of Fuel Injection I offer assembled crimped hoses made to the specific model as well as replacement Polyamide Tunnel Lines as shown in this photo......

.....and also offer this in 7.5mm or 9.5mm in E-85 Rated Braided SS.

For information, please email me only. NO pm's as my box is almost always full.

It´s true, that 1969-73 cars used 7mm and 9mm fuel hose, as listed in the PET, from the factory. Some 45 years ago.

7,5mm and 9,5mm fuel hose will replace these with no problem on your 1970T.

The short answer is that the ones to go for today is Cohline 2240.0600, which has this inner/outer diameter: 7,3mm / 13,5mm, and Cohline 2240.0800, which measures 9,3mm / 15,3mm. This is also the type of hose that Porsche uses as replacement hoses for early 911s today.

Use correct Norma clamps.
