Will a 180* AN fitting fit off an aftermarket fuel rail behind the alt?
I know that people often have to do trimming on the back of the alt to fit the 90*, but I need to do a 180* off the end. Radius should be very similar to the 90 I would imagine, but the fitting costs $30 (PTFE) so I'd like to know beforehand. Thanks.

Standard truck intake with ebay billet fuel rails.
A member here has these rails and the 90* fitting clears his alt but a hair, however, I'm not sure if the 145 alt is "deeper" than the 105 alt. Also, comparing the dimensions of a 180 fitting vs 90.

Haven't tried it myself but I don't think it will.
I still have the 105 alt and it I have the tightest 90 fitting I think is out there. It barely clears the back of the alt but it does. I don't think a 180 would be able to turn at the radius my 90 is at. But if you order the fitting through summit, they have the best return policy. 90 days no questions asked.

I have used those rails on a TBSS intake with the 145 amp alternator. The 180 deg did not fit. I ended up using a short radius (block style) 90deg and it cleared. The normal 90 deg would not clear either for me.
I ended up going -10an feed into a split -8an into the back of the rails, then block 90deg out of the front of the rails into the pressure regulator, then stock feed as the return.

That might be me that you were talking about who is running those rails with a 90*, becasuse I am. I would recommend contacting the company that sells the fittings and see if they can get you the dimensions on them to find out whether the 180 sticks out further or not.
This is the supplied 90 from that seller. I have the larger alternator. The 90 clears because it starts to curve just before it hits the alternator. I wouldn't be able to make it face any other way without hitting. The 180* might fit if you run your line back between the intake and fuel rail, probably not if you run it outside of the rail.
