FPR and ORB Swivel 90

[Fastduramax]

So I mounted my FPR to my fuel rail with an ORB swivel 90 and feeding both fuel rails from the rear as per Aeromotive recommendation for optimum performance... My question is is an ORB swivel 90 designed to withstand engine vibration or is this a no no ?

Never had an issue, but you could also put and isolating washer. Might take some out, except for the snort snort hog cam wiggle...

edit:
looked at the picture again, no bracket. See why you're concerned. Alternative would be to mount the reg on the fender well

Thanks Bent, yeah dude on the Edelbrock forum said negative, no bracket no can do it will crack the fitting and that was my thought exactly... I was trying to follow the Aeromotive plumbing diagram to a tee but seemingly not doable with this ram jet type manifold ugh !

Yeah my regulator is on the wheel well, just the line coming off the rail. Engine can wiggle all it wants, isolation washers on the fender
Not as clean, but oh well

I hear ya, I hate hoses running everywhere and the FPR creates 3 more ugh ! And yes the 572 is gonna wiggle, a few rotating inches no matter how well balanced, largest bump stick to be somewhat street friendly in a 4800 pound boat anker and ORD motor mounts...

Not to derail this thread but what size fitting are you using from your fuel rail? I’m wanting to run a similar set up on my pro Flo 4 and having a difficult time determining what fitting size to use on the rail.

They are -10an

Thanks!

But... I'm not sure if all fuel rails are the same size, mine is the #35883 system which is the largest they make with 60 Lb/Hr injectors so double check or ask Edelbrock if you are using a smaller system... SweetK30 may be able to answer that question also he's pretty Bro-Flo savvy PM him...
