RE: New fuel tank - Am I missing something?

The return line answer helps my question as well, but I have one caveat. If*I replace two steel tanks with two poly tanks that don't have a crossover but still plumb both tanks to the feed, will the fuel be drawn equally or is there a problem I'm not realizing yet?

With multiple tanks it is*a plus*to have a valving system to permit drawing and returning from any tank.*Normally have valves postioned return to the tank you are drawing from - this prevents spills and fines.

RE: New fuel tank - Am I missing something?

my current steel (very rusted tanks) feed to the single fuel feed line filter, but they have a crossover for (i'm guessing) equalization. I'm wondering that with the small amount of return by a lehman do i need to worry about that or perhaps i should just drill and tap two ports on the bottom of the tanks and make a crossover. just a little confused on best course of action when i replace with two poly tanks!

The return on a Lehman is mininal so I wouldn't worry about it.

RE: New fuel tank - Am I missing something?

thanks for the input, but I'm still a little confused on whether or not I should put in a crossover or not and if there would be a problem if I drew from both tanks at the same time or is it neccessary to put a valving system in place.

I can tell you I do not have such a system on my tanks and they go down at the same rate.

The return line should go to the source, in this case, the day tank.* Granted the return flow is small, but if you have the choice there is no question it should return to the day tank.

RE: New fuel tank - Am I missing something?

do you think there would be any issue if I Tee'd the return line to both of my new tanks?

*If you are going to do that, just put a valve on each tank side of the T and you can select where the return goes.

If I understand your situation, you have only two tanks on either side of the centerline, and no day tank.* If that is the case, then the simplest installation would be to replicate the tank combiner tee you already have and feed the power plant from that.* With them combined, as they should be to maintain trim, it is immaterial where the return line goes because you effectively have a single tank.* Put shut off valves out of each tank in case you want to isolate the tanks for some reason, as well as a drain valve for sediment removal.
