4.0 OHV Fuel Fitting Sizes

[Rustbucket350]

Does anybody know what size and type the fuel fittings are for the regulator and fuel rail? I'm trying to come up with a cleaner looking alternative to the stock lines.

Maybe I should rephrase this... I'm trying to run braided AN lines for my 4.0 swap and I don't have the fuel lines. The regulator looks like a 14mm x 1.5 and the fuel rail looks like a 16mm x 1.5. I'm not sure if it's an inverted flare or what though. I know the easy way is to go get the factory braided lines but thats way too easy. Has anybody ever ran AN hoses on a 4.0?

I've scoured the internet and looked at all kinds of adapters and I'm still scratching my head. Does anybody have a picture of the female end that connects to the fuel rail or the regulator?

Did you ever figure this out? I built my 4.0 and I'm trying to connect-8 lines to the fuel rail

The OP hasn't posted since April. So, you may be in for a wait, if they are coming back at all.

I found another site that had a thread from 2013 that says the fuel rail has M16x1.5 feed and M14x1.5 return. I already ordered fittings to adapt it to my needs.

Good to know for the next person looking. Thanks for the information.
