I’m going purchase a tank here shortly. I currently have the original tank from the carb’d 231 in the Cutlass and I’m worried about starvation.
From this thread, I gather a neck-less Spectra tank will work. Seeming how I am running e85, I will be adding an access port to have both Walbro 450s running in the tank. I will have a “y” outside the tank to merge to two pumps together.
The way I had both pumps hanging inside the tank just kept rupturing the fuel lines. No bueno 👎🏻
I'm not a fan of the dangling pumps. I do realize they work, and guys have made oodles of go with it, but I'm not a fan for a street driven car with momma nd kids in tow to get ice cream when an issue develops. External pumps are SOOOO easy to service, diagnose and repair that I can't not use them.
If your tank is in good condition, then sump it. If it's crappy, then grab a $100 tank from Advance Auto and put in a sump. Use your current pickup (modified) to work as a return or weld in a bulkhead fitting on the forward side of the tank.
All of my rec has budget as a concern. If budget is not a concern, then I'd be running a cell with a fuel tree - but budget always seems to be one of my concerns lol.
