keeping dual tanks

[putt2014]

How do I keep dual tanks when doing a ls swap. To my understanding the original tank selector valve can't hold the added pressure of the ls fuel pump. What is the best option for retaining the use both tanks.

I have an LS dual tank harness using a Pollak valve rated at 65 psi. My harness kit utilizes a main IGN control relay which triggers the selector switch and it flips a LH or RH electric pump. Walbro makes a nice fuel pump to add to your stock 87 TBI sending units. Relays mount underdash near fusepanel and everything else wiring wise is updated to run dual electric pumps.
I offer the harnesses for $289 if interested.

I will keep your contact info for when I put back in a second tank. Need to get it running on the first tank at the moment.

Looks good. But what kind of fuel lines does it require?

Stock 6 port valve is ok in LS service. I am currently running this setup right now with no issues. I used earls fuel injection hose where needed with fuel injection hose clamps. 4 months, so far so good.
