REQUEST: Converting 04 to return style fuel system...

[Mahonroy]

Hello, I am requesting a DIY, walkthrough, help, information, etc. On converting a 2004 Hyundai Elantra returnless style fuel system into a return style fuel system. I heard about needing to obtain a certain year of elantra's fuel rail to do this, but would like more information, also on how I would go about installing it. Thanks! :D

I thought only 01-03 were returnless... Or am i wrong?

As far as I know, the 04's are Returnless as well.

You dont have to change the fuel rail, you could simply add an adapter to the end of the stock rail and use it to mount a regulator and a return line back to the tank :)

Ford can you answer, what are the advantages of Return vs. Returnless?

[SWortham]

Is this really necessary when you have MAF? I mean, there are a lot of issues with trying to turbo an engine with MAP and that's why a return-style conversion can be a nice option. That way you can rely more on a fuel pressure regulator to control fuel delivery instead of just the ECU and an SAFC. But I didn't think the MAF system would have those limitations.

Can you jump in here Ford, and help us out?

thread locked, do a search in the FORCED INDUCTION sections (here and archived), myself and others have posted TONS of information about fuel delivery issues and returnless conversions.
