I have a fuel lab regulator with a aem rail. It would be easier on me to mount it on the end of the rail, as in have a coupler joining them two. Would the regulator get loose over time? Or should I just mount it on the body/firewall.

 

i wasnever a fan of hanging that much metal off of the end of the rail but thats my 2 cents.

i put my aeromotive reg on the firewall.

 

ive run an aeromotive on both the end or the rail and on the firewall and neither were a problem. its not like it weighs a ton. i personally would do the rail and make a bracket to thold the regulator even though its onthe rail for added safety and that will make sure it does get loose and or break off. i made a simple brace for mine when i ran it that way.

 

I ran my aeromotive fpr off at the end of the rail myself too. Not sure which one you have but fuel lab came out with a smaller version.

 

I have the regular version.

I have the fittings to either mount it on the rail or the firewall. I think I might try the rail and if it gives me any problems I will just mount it on the firewall.

 

IMO id go with the firewall just to reduce vibration that the motor may produces and absorb causing a less acuret reading/delivery possibly.

 

Is there any set backs to mounting it on the fuel rail... I mean performance wise?

 

The fuelab regulator on the end of the rail is fine. Just make sure you use the steel fitting to mount it.

 

no, it will regulate fuel pressure regardless of where you place it

and why the hell did you bump this thread from the grave?
