Gday. Just wondering on my rb25 head standard fuel rails are like 5/16 feed & return sort of thing.. pretty small. I have two fuel pumps & a 2L surge tank. Both pumps are running an individual line each under the car & I have a 3/8 return line plumbed into the bay.. Would it even benefit having two pumps with such a small feed & return on the stock fuel rails? I might not need it for 740cc injectors but two would be better incase of failure etc, not sure if it will bottle neck etc.

Anyone? Going to upgrade the injectors down the track should I just run both lines into one or is it going to stuff the fuel pressure up? thanks

It will be fine. Later on you can upgrade to dual feed rail and make the most out of it. Make sure you have one-way valves on the outlets of your pumps. Peace out.

I have the rail and the injectors I just decided against it right now as I have a running car & I would go all out with braid etc etc when I really should just stop now and get a tune allready.

i had something similar on on vl i had, i used 2x 3/8 line feeds with the 044s and used the 2x 5/16 standard steel fuel lines as returns and never had a problem, so should be all good......
