1967 220 Wagon, B20E D-jet conversion.

This is where D-jet conversion project ceases to be a bolt-on, drill-hole, run-wire project.

Fuel Pump Mount
I was climbing around under the rear of the car and found that, due to the low-slung fuel tank and slightly "cramped" space between the tank and the differential, I can NOT bolt up the 1800E's shield/pump bracket. I'm thinking I'll need to put it up at the top of the rear wheel area, hanging from under cargo deck. Not as clean as I wanted, but I guess it will have to do.

Return Fuel Line
After mulling over my parts and finances and chasing down prices of steel fuel line for my supply/return line, I hit upon using the fuel line pulled from my parts car/cabriolet. It'll be a while before that car is driven so I'll just order some new line when I have some more dough. Using a second stock line has the advantage of being pre-bent to the amazon's underside.

I've got two issue here. One - is that I think someone once mentioned that the supply line needs to be a 3/8" pipe, not the stock 5/16" pipe... Is that right?
Two - return line port in the fuel tank. I'm not sure about how to install a second fuel line port. I think a barbed hose and a drilled/tapped hole in the tank, but I worry that it will not hold properly and that I'll be dropping metal shavings into my tank - only to suck them into and maybe through my filter onward to destroy my pump and injectors...

How have you guys installed a return line port?

Tank Venting Cannister
How does that giant "beer-can" venting/collecting apparatus work? You know the one in the 1800E's tail that catches the gas from the fuel pump vent & vapors condensing in the filler neck. Do I need that thing? Nobody ever mentions it...

Ports
A final thing. Where can I hunt up a replacement vacuum nipple for the intake and another screw-in PCV valve?

I'm nearing the home-stretch on this project...

Thanks as always.
