Espar B4 Fuel Plumbing Suggestions

[Flux]

So i have a B4 on the way and am hemming and hawing on how best to plumb in the fuel line. I have a custom steel tank from Aero with the stock Sending Unit. While researching my sending unit I see that there is an alternate unit with an auxiliary tap on it. I then saw someone plumb to that on a Transit. I would have to buy another fuel pump.

So I could drain and clean out the tank and drill a hole for the Espar pickup tube. Easy enough I guess save for a lot of hassle cleaning it out. I also thought about drilling the top of the sending unit and dropping the pickup down through there. Seems like that could work if there is space on top and I can get the tube down to the base. It's a plastic top though and I have some concern about cracking it with the pressure from the pickup tube gasket.

Or get a QD fitting, new fuel pump, and do it that way. Easiest but cost $$ for the new unit. Certainly not opposed to that though and then I have a new unit and install would be pretty fast and painless.

Anyone plumb one of these in and how did it go?? Dropping the tank is a decent undertaking so I gotta think it through.

And yes, a B4. Wife get's cold and that does not make for fun van times so I went with the bigger unit.
