Started laying out the fuel system

We started to lay out the fuel system....repro stainless tank.....Rob Mc sender/feed/return....Aeromotive pump and filters....-8AN going to the carbs....-6AN coming back to the tank. The lines themselves will be part 1/2" stainless tubing, and part Aeroquip braided stainless line.

I like RobbMc stuff. I'm using his pump, filter, regulator, and starter. With that blower motor and as much power as it's going to make, I'm curious why you're not putting a sump into the fuel tank?

GTOcop, yes all the links and suspension parts are adjustable. BEAR, I was thinking about a sump, but was advised I don't really need one. The tank is baffled......

They make baffled tanks??? Well, strip my gears and call me shiftless... If I'da knowed that, I coulda saved myself some grief and my bride some more gray hairs (from me welding a sump into my original tank...)

thats an interesting rear suspension. i have experience in circle track suspension fabrication and design and i cant understand why someone would design a suspension with those angled upper arms. i am sure there is a good reason but it seems to me it would be more efficient to run the arms straight ahead and use a panhard bar for side to side location. can you tell me the theory behind that design?

Hey Eric, am I hallucinating again or did you originally have a Watts Link in that chassis?

@freethinker... the triangulated non-parallel upper arms also locate the axle side to side, doing the job a panhard bar would do. The down-side is that unless the ends on those upper arms can swivel (the factory ones don't but many aftermarket replacements do, and it looks like Eric's probably do too) the upper arms can "bind" and resist allowing the axle to freely move in a body roll situation like in a corner. The factory triangulated arms used rubber bushings everywhere so they could deform and allow some roll movement, but they still bound up. As a panhard bar moves up and down through its arc, the axle moves from side to side a little bit. With a Watts Link, that doesn't happen. The axle stays located in the same spot side to side but is still free to articulate in all the directions it needs to.
