I am revamping my engine bay and have my FPR offset. Obviously I have a splitter in to send fuel to either side. Do I need to make sure that both runs of fuel line are kept the same length or can they be different lengths. I dont want to cause any issues with the fuel prioritising one side over the other. It will mean both the feed and return to the FPR being different lengths.

 

In a perfect world they should be the same length! In practice its not too important!
Look at the stock setup!
Mine is far from equal length and works fine!

 

It's quite important that I don't end up with any fueling/leaning out issues.

 

Any other thoughts on this?

 

Even bought kits like the APS one I have are not equal length. So no issues.

 

Cheers. Starting to put my mind at ease.

 

The pressure in the lines will be the same no matter what length so long as it's plumbed up correctly. I would like to hear the argument of needing the fuel lines the same length.
