<p class="MsoNormal"><span style="font-family:"Aptos",sans-serif">For years I just had the stock metal line in my full-race Spitfire, which ran under the floorboard. Eventually it got pinched. The system I installed was an ATL cell in the trunk, with a duckfoot
pickup in each back corner, two Holley red fuel pumps leading to a T-fitting – all in the trunk – then a single line through the passenger compartment just under the door (as far from me as possible) to a regulator under the hood mounted on the firewall, then
to the carbs. Regulator has a gauge installed where I can see it. I don’t really refer to it while driving (although I can), primarily I use it when setting fuel pressure to the carbs. For the Spitfire 2½ pounds of fuel pressure was wholly sufficient (the
Holleys would deliver 7). For the TR6 maybe something else. Oh, and ALL lines braided since they were all vulnerable.

<p class="MsoNormal"><span style="font-family:"Aptos",sans-serif">I ordered my fuel cell direct from ATL and specified the two pickups. Roundy-round guys usually only have one, in the right-rear corner, because they only turn left. We go both ways. I also ordered
the cell with a dipstick to know the fuel level. And then </span><img width="20" height="20" style="width:.2083in;height:.2083in" id="_x0000_i1025" src="https://cdn.jsdelivr.net/gh/joypixels/emoji-assets@v7.0.0/png/64/1f606.png" alt="😆"><span style="font-family:"Aptos",sans-serif"> discovered
that while the cell had the place to put the dipstick in, the foam inside did not! I had to take the top off, pull the foam out, figure out where the hole needed to be and cut the hole in the foam. Then the first time I filled the cell, I filled it one gallon
at a time and marked the dipstick. It’s worked great ever since. I also learned not to fill the cell full to the top because it would splash out of the overflow and corners got all excited that I was spilling gas. Filling it a gallon short got me through all
races. For autocrossing (with the two pickups) 3 gallons worked fine. <o:p></o:p></span></p>

<p class="MsoNormal">Brings me to my questions. What size fuel lines – 5/16” (-5) or 3/8” (-6)? Also, thoughts on 100% steel braided PTFE, or combination of metal fuel line (front to back) with braided to connect to the fuel cell and Webers? Fuel pump,
filter and pressure regulator will be in the trunk with the fuel cell. Return line? The 6 previously had fuel injection and a fuel return line. Not sure it is necessary for the Webers.<o:p></o:p></p>
