v-8 conversion fuel help

[rubydist]

The "returnless" fuel systems still have a return. There is a pressure line to the filter and a return line back from the filter to the tank. Rather than have the pressure regulator on the fuel rail in the engine compartment, the regulator is on the fuel return line in the tank. So the filter has 3 fittings - 2 on the tank end and 1 on the engine end of the filter. Under normal operation, the excess fuel is pumped to the filter and back to the tank, rather than all the way to the engine and back.

If you don't have any return (and therefore have no regulator) your fuel pressure will vary all over depending on how much fuel you are using, since the pump pressure varies with flow - but it should be way too high most of the time.

I think I could probably hook something up but not sure how to get it back to the tank I don't mean the line I can run that I am talking about how it enters the tank ?? On the v-8 swap page he says that you can run one line but need an explorer regulator I wish I knew where to get one of them or is that in the pump?? I am surprised nobody else has dealt with this unless I am in the wrong section?? either way thank you for your help I am going to keep searching..

If you are using the 1996 tank, which used a return originally, it should have a return port capped off on the sending unit. Unless you changed something and now it does not have the return port anymore.

I am going to pull the pump today I hope lol meantime going thru my pile of "stuff" lol I did find the two rail along with all the lines going back to the tank from the door /explorer It is a good amount of work but thinking maybe I should just go back to the two line system?? I am lucky enough to have a lift so i know I can get the lines in maybe just easier to do that?? going to check it out today hopefully I will update as soon as possible Thanks again

I am using the 99 ranger tank The explorer /donor is gone but I did save all the lines and fuel rail hope going to take off bed today and see if I can get the donor lines installed maybe that is the easiest way.. I do have access to a lift luckily so I think I can run the lines without to much trouble at least that is the plan?? Thanks again I will update as soon as figure out what I am going o do
