70007 fuel rail set up
wanted some more info on hooking up the fuel lines on my 70007 ultimate system are both lines at the rear of the fuel rails feeds? or is one a feed the other a return?
Sorry, I was cooking dinner.
If you have the Fitech regulator, it needs to be placed in the return line near the fuel rail. So, you should have a feed line going into one fuel rail and a return on the other side with the regulator. Making a complete loop. With this configuration you can prime the system by running the pump for a minute or so....
im using a walbro in tank pump with a corvette regulator/return system so do I run my fuel line to one side of rail and cap off the other side ?
Ok, so you are running the regulator filter like the oem? In that case, I don't believe it would matter to have one feed or feed to both rails. But, you will need to bleed the system in some way.
ok thanks hope dinner was good lol I will do that I have also read another forum about using the fuel pump wire in the harness should I run this or will it matter?
From what I understand it doesn't matter on the LS unit.
If you're using the Corvette filter/regulator, there is no return from the fuel rails. You can feed the front of one rail, cross over to the other rail n the rear and plug the front of it. Or install a gauge.
There's no need to bleed out the air. At 55PSI, any air is gone as soon as it fires up.
