there are 4 pipes at the fuel tank, which is what?

and more importantly, whats with the float at the top? when blowing through the pipes, i discovered that air or fluid, or whatever comes in, can only go one way or the other...

its pretty apparent though, that the one of the long pipes is fuel in and out. im pretty sure there is a siphon between the tanks and perhaps the other pipe plumbs them together

In my email I was talking about the front tank which does the diesel pick up; not the rearward tank. Must be the heat.

so what about the return from IP?
im adding the third tank, and plumbing it to rear stock tank, do you think i need to concern myself with the pipe from the air float to the front tank? plug it? keep it attached to the front? make a connection for it in the rear?

do i need to return veg to both tanks?

now where getting into the realm of the WVO forum, but i figred the pickup questions were suitable for the tech forum...

Yes, use one top line as a return and the other top line either as a vent to a check valve (ask Collin - also ask how my old computers are working) or to the top of the tracker tank. You should still use a one way check valve off any one tank, mounted nice and high up under. Can't remember where the float valve was plumbed to?

No, set up properly it'll well keep level.

It's all good.
