Just wondering.... I heard the '98 fbodies have a regulator on the rails like the '97 vettes. Is this true? If so, I would just need the custom fuel lines and not the aftermarket regulator? Anyone know for sure? I need to look at my intake and fuel rails at home, just wanting some thoughts/experience too?


Thanks!

 

I have a 98 and up and i need the regulator before the fuel rails....

 

Supposedly '98 fbody fuel rails/lines/regulator are different than the '99-'02. Not sure, that's why I'm asking.

 

I'm not sure what that thing on the fuel rail does, however the fuel is regulated at the gas tank and therefore unless you create the same effect, it needs to be regulated in the engine bay and you can re-use your return fuel line....

I looked in my service manual, and nothing is mentioned about the fuel rails and regulating fuel pressure...

 

I looked into this for my LS1 swap:

'97-98 Vette have regulator on the rail and feed/return lines.
'98+ F-body have feed only and a damper on the rail.
'99+ Vette have feed only and a damper on the rail.

New discounted GM price on a '97-98 Vette rail and regulator was more than the Aeromotive external regulator, so it was an easy decision.

 

Yeah, that is what I always thought..... '97 and '98 vettes having the regulator, and '98-up fbodies not having it. Hopefully they sent me the right setup.... just getting some stuff from fbody motorsports. I hope to have this thing up and running before christmas!

 

GTA91,

my suggestion is instead of hunting for the 98 F-BODY fuel rails(which you dont know much about), just find a aeromotive fuel pressure regulator and the -AN Fittings. Its easy to do, I thought it would be extremely hard to install that, but turned out easy.

 

I've already got the '98 fuel rails..... I was at work when I posted this and not able to look at my parts to see if there was a regulator on them or not. I'm at my girlfriends now, so I still haven't looked. LOL I do have the aeromotive regulator and lines coming.
