Fuelissues

I will update the fuel lines and I wonder how much difference they are on AN6 against An8. How much fix runoff from fuel tank to the first fuel pump ??

? Not sure I understand the question completely.

Stock tank to front pump is gravity fed, and 12mm ID hose so equivalent to 8AN already.
Going larger means modifying the fuel tank.

6AN chassis lines will support well over 600whp on gasoline.

If you are making over 600whp and running ethanol, use 8AN supply and 6AN return PTFE hoses.

Unless you are changing to larger pumps, the outlet size of the Banjos at both original pumps is 12mm.

Not much benefit as this is the restriction in the system.

Also, be very careful where you buy the AN Hose. Lots of Chinese JUNK out there.

To confirm what you have, peel back the SS braid and you should see the mfg info and date. Without this, you do not know for certain where or how it was made.

There is a point where the factory check valve and 12mm banjo fittings become a restriction.
If building a big HP ethanol car, both these items must be replaced.
