Do you think 6mm copper is enough for a 4.6?

Hi,
I swapped a front end kit BRC Sequent 56 to replace my single point Landi Renzo.
Landi Renzo used 6mm copper but BRC uses 8 mm.
I used a diameter converter but i have some LPG cuts when i demand power.
Do you think i should replace all my lines to 8mm?
Thanks
Florent

I doubt if that makes any difference to be honest.
The only time I know it matters is for filling the tank - it is quicker to fill with 8mm. If you think it takes 5 mins to fill the tank with 6mm pipe, it takes a few hours for the engine to empty it. So the engine can easily draw enough LPG to run through a 6mm pipe.
Chris.

I've readen both :
-a UK specialist advise 8mm for any V8 range rover
-a french specialist says all his +6.0 liters US trucks and even V12 bimmers run 6mm

My Chrysler 300c would switch back to petrol with 6mm pipe feeding from the twin tanks to a t-piece then 8mm from there to the engine, but it is fine ever since I replaced the 6mm with 8mm pipe. 350bhp engine.
My old 4.7 landrover V8 would sometimes get upset above 5000rpm with 6mm pipe.
From experience, I only install 8mm pipe on V8 or large capacity engines.
