bulkhead is stamped steel that's about 3mm thick.what material is the bulkhead? If you only need one connector hole, a die grinder or dremel with an appropriate point bit (not wheel) is the right tool.

@Jehannum I inherited a couple dozen of those from my cousin with the lathe. It would only help with the one on the bottom right as they are all a complete hole, but I could see if I have one that size and mail it to you.Like this

find your size/shape
Dunno if theres one exactly for your application, tho
There may be ones from other sources that would be closer to size
i presume its something in place, as in part of the car, cant be taken out easily?bulkhead is stamped steel that's about 3mm thick.
No, it's the sending unit for the fuel tank, I already have it out sitting on my garage floor stinking the place up.i presume its something in place, as in part of the car, cant be taken out easily?
But how will they punch it? It's 3mm steel. Most machine shops don't have a press for the job, somebody would have to set it up if they did. And on a single pass punching that would leave hell of a burr. And no, you can't do that on an arbor press. *I worked for a Dayton Tool distributor for 8 years - I made punches like that frequently. Nobody keeps them on hand since even though holes sizes may be fairly standard, material thicknesses are not and you have to have proper punch to die clearance. Which varies by material and thickness, greatly.ah, then the clear choice is to take it to a machine shop with a d punch. Thats gotta be a standard d punch size.

Last idea . . . find someone with a CNC plasma cutter. Should be lots of them who'd work cheap - they all thought they'd make a killing making customs signs and lawn art.
It's the sending unit, so yes, all the things are sent from it.If it's the "access cover" thing you take off the tank that the lines go through, holds the float for the gauge and all that, 3mm sounds kinda thick to me, though I've never measured one.

My Datsun has an external fuel pump too, but the removable bulkhead on the fuel tank is still called the sending unit.My Nissan trucks of that era had the fuel pump mounted outside the tank. Maybe they still called the rest of it the sending unit, really don't know.

Yeah, I'm pretty sure that's what it comes from (sending the tank level).OK, though the term sounds weird to me seeing as there's nothing in that "unit" capable of "sending". The fuel pump is down the line. More like "drawing" from a well and "sending" it to its destination.
Although the signal from the float is still getting sent to the gauge from that unit so I guess it could be a sending unit, but not a fuel sending unit.
My '67 Mustang has a sending unit at the tank and a mechanical fuel pump mounted to the block.My Nissan trucks of that era had the fuel pump mounted outside the tank. Maybe they still called the rest of it the sending unit, really don't know.
Do you also have a tank drain?My '67 Mustang has a sending unit at the tank and a mechanical fuel pump mounted to the block.
Also, mounted on the bottom of the tank.
Only because it is a new tank. Original did not.Do you also have a tank drain?
The Datsun does, and I think it's a requirement for any car with a sending unit not on the very top of the tank.
