I have had some new fuel lines made up out of polymer coated Alli hardline the flow is in 10mm with -6 fiber braided s/s reinforced hose on each end, compression fittings both ends and crimped to the original fuel rail adapter, there is also a non return flap valve attached in-line at the engine bay end,

Then the return is done in 8mm due to the -6 hose being to big to clamp to the fuel regulator spigot and the nylon pipe at the tank end,

So the Questions are:

1, Does it matter if the return pipe is smaller

2, Do you really need a non return valve in the feed

3, What is the max fuel pressure of a stage 3 with a 044 pump

Also would like to know what you guys used, and any pic's of the connections you used would be nice

Come on Gents, need the answer to question 1, for the weekend if any one knows it.
