Size of the fuel lines

[Fii]

The 20 year old fuel lines are very rusted in the tank area and they did not come loose on the red car. To take the fuel tank off, we broke the line, and it needs replacing.

What size is the stock fuel line and the return line? Do we need bigger lines if we plan to use a slightly tuned blacktop engine in the future or will the stock lines be good enough for the task? This would be a good moment to decide what lines to use, since they need replacing anyway.

Just use whatever you can find cheaply. Getting custum fuel lines made means $$$$$$$$$$$
Unless you have some cheap options for fuel resistant, triple breaded fuel hoses there in Latvia. In which case I will be ordering from you too!

Usually its more efficient to just use whatever is under the car or can be found at the junkyard.

Ordinairy fuel lines are cheap. You just have to bend it with the right tools.

I will see what I can get. But how much reserve there is in the stock lines? Is there any reason to get larger lines if the target is about 160-180hp?

8mm LPG copper lines braided with PVC are cheap and reliable alternative ;-)

do not change the size of your fuel lines (unless you started with SR type AE86), they are perfectly good for 300hp as well!
:wink:
oh, just to add: intake 8mm, return 6mm. :wink:

What diameter fuel lines does the SR5 have?
