Help. Aftermarket 70 series built fuel tank hose locations (1 Viewer)

[olandevo]

Hey guys, kind of a specific question i couldn't find anything on in search.

I have an after market built 70 series fuel tank. I am not sure the manufacturer. Likely out of AU? I am trying to run my hoses, and vents correctly, I feel like i got it right but don't want to screw it up.

Could anyone with insight on a tank like this help me out?

Edit:
I believe it is a Brown Davis tank, i have sent them an email as all the tanks on their site don't exactly look like this (Older model?) hopefully they will respond soon.

1/ Small Feed
2/ Big Return
3/ Filler neck drain
4/ Fill spout
5/ Vent 1
6/ Vent 2

Am i wrong? Should where i think the vents are actually be fuel in/out?

TIA!

i have a brown davis in my 70, dont know if its the same tho
Ill have a look at it and see what i can see
The drain on mine has started seeping so i should probably roll around under there anyways

Thanks man! They got back to me, but said it doesnt look like one of their tanks though he did tell me some tips on how to tell which port is fuel pickup (internal tube run's to tank bottom). Glad i asked because i'm probably wrong in my assumptions. After studying a Brown Davis schematic of a similar tank, What i believe things should be are:

1/ Expansion/Vent
2/ Expansion/vent
3/ Filler neck overflow
4/ FIller spout
5/ Pickup-Feed line (3/8")
6/ Return line (5/16")

If you could confirm that would be awesome.

TIA

Edit: In case anyone wonders about this in the future this is the correct configuration. You can look into the port with a flashlight and see the pickup tube.
