So I'm plumbing the whole car with AN lines and I just thought of something today..

With regular lines and stock filters, I always put one filter under the gas tank and a second one above the transaxle. I did this because I didn't fully trust those cheap plastic/paper filters..

Here is the filter I just ordered:

Do you guys think I should double up filtration again? or should I be fine with one?

The plan is to go tank => filter =>pump =>regulator => carbs

One should do it if the tank has been cleaned and sealed.

I only run 1 filter.

I enjoy the hell out of my multiple filters. I made sure they were as horizontal as possible which came about after cleaning them for the first time. I also added a dab of grease to the threads of the filter. That Earls filter uses boss o-rings which are easy to get. I've sprayed the intranet with these same pictures for about two years because now everything is kinda dirty.
I have a filter after tank before pump, before regulator, and before carb. Overkill but I have found debris in the first two and none at the carb.

Nice pics!

How did you handle running the line to the engine?

I know the best method is through the tunnel, and NHRA standards says it has to be inside of the frame, but in the interest of getting it done, I'm thinking of running down the passenger side. I don't have running boards and there is a section between two lips (the pan and body I believe) that seems like it will be a perfect fit for my hose..

In the long run when I have time/money, I'd like to run a SS line with fittings similar to brake lines, but for now my thought process was " god forbid it splits and catches fire, I want it on the passenger side so I don't have to jump over flames to put it out.." Course with AN lines, it shouldn't split anyway, but you never know..

I ran 5/16 aluminum tubing from front to rear. It exits the chassis in the normal spots. I had to make two access holes in my tunnel so I could fasten it down. I slipped a piece of split rubber hose over the new line and ty-wraped it to the old line, just in two areas. It seemed super tight and stable so I closed up the access holes. There are many better ways of doing it but Im getting old and this will last my lifetime.

5/16 nut & ferrule to #6 AN. The ferrules dig in one good time and I never test them again. Just use two wrenches of course. My only regret now is the alcohol threat to my steel braided lines.
