Fuel Setup for Build - Rail and SFMU

[david-b]

Ok so for my build I will be using a SFMU with it looks like a 3:1 disc. Now, I have a 95 that has the FPR built into the rail. Is it true that I have to cut that out in order to get the system to work properly? Also, can't I just get a 96+ fuel rail then and not have to worry about cutting the FPR out? I'd rather not have to deal with a hacked rail (piece of mind)

Thanks for the help!

You could use a 96+ fuel rail, but then you'll have to remove the Schrader valve to use the test port for the return. If you decide to stick with the 95 rail, you'll have to disable the FPR.

For either option... how hard is it?

To remove the schrader valve on a late model fuel rail: The valve core just unscrews; use a schrader valve removal tool (i'll get pics tomorrow of mine if you want to know what it looks like) or something along the lines of narrow-nose pliers. If using pliers, be careful not to damage the seal on the valve, that is if you think you may ever want to re-install it in the future.

You can make your own determination after reading Locke's post, but I personally think it's one of those "six of one, half a dozen of another" situations.

Sounds good. I remembered I have a spare 95 rail laying around somewhere so I'll do it to that one so I don't ruin my good one. Thanks guys.
