I'm getting work done on my suspension and fuel tank setup. Fuel Pump
I made a mount ring for the Miata fuel pump assembly. I was planning on putting it underneath the fuel tank surface, but the fuel pump assembly has a lip that descends past the accompanying gasket. So, the mount ring will go on top with a gasket underneath to get required space. I'm going to install screws/bolts from the bottom, and thread into the mount ring. The threads will be longer and stick up through the pump assembly plate, and I'll tighten nuts down on it.
Q: Can tighten a fastener "twice", as in the above?Fuel Level Sensor/Sender
I found a suitable fuel level sensor assembly from WEMA USA. (http://www.wemausa.com/tank-sensors/det ... ensors.htm
). They're half the price of a comparable unit from Summit or Jegs. I bought the accompanying under-ring, too. Still need to buy a hole saw kit for the hole, though.Fuel Filler
I'm trying to figure out how this whole thing works. Because this tank will be lower in the chassis, I'd like a remote fuel filler cap in the rear of the car, or on the top, in a corner, perhaps.
I've found a few components that I think might work. For the tank side (2" vs. 1.5"):
For the filler side, there are different cap styles. I'm planning on using the Miata's charcoal canister and emissions controls systems.
Q:What do I need?
Do I need a vented fuel cap?
Is that easier than venting the fuel tank somehow else?
Can I bend this fuel hose to get between the filler and the tank flange, or do I need a hard tube to make a bend in between?
