-6an fuel regulator return line fitting

[49-blues]

Anyone know the correct thread size to put a -6an fitting on the bottom of the fuel regulator to get more flow? and maybe who sells them.

Believe it is 14mm x 1.25. Earls sells them.

No such fitting. They're available straight but you have to use a 90. Take a 1/4"npt aluminum 90 and cut about half of it off (you need all the room you can get. Then you can thread it in sort of, it's not the right thread but it will go and stay where you want it. Then have someone tig it for you.

The discount hydraulic hose looks perfect, Keep in mind, the regulator itself is the restriction, I think they are very small inside, like .184 inches...

These will fit, but its very tight... I was going to use another 45* to angle it up after the 90* to be able to run the line to it, but then I just got a dedicated -6 dual port regulator and had turbofabricator make me an adapter to the factory fuel rail.

Thanks guys -I just ordered 3 of them from discount hydralic hose, since I ll ve using E-85 I thought the steel fittings would be the best choice.

I will get a pic of mine but I used a XRP 120 or 160 degree...I will get a pic of it.

If the stock regulator doesn't work, you will have to step up to a larger unit. Read this thread for a solution: http://www.turbobuick.com/forums/general-turbo-buick-tech/338587-my-fuel-system-parts-list.html

I tried doing the fitting initially but if you run the return hose back towards the driverside firewall it won't work and jams up into the intake. But the way Scott runs the return line it obviously works that way.

I ran the return line with that fitting and ran it in the stock location and hooked it to the factory suppy line with this fitting
