Fuel pump setup for dual tank ls swap
« on: November 22, 2016, 09:29:15 PM »
I have an 86 k20 with dual tanks.  I'm putting in an lq4 6.0L and need to figure out the fuel pump.  I'd like to keep the dual tanks and for simplicity would like to keep the stock pickup.  Can i use the switching valve out of a TBI truck and use a Walbro pump in line between the tank and the fuel rail? Is there anything I'm not thinking of? Thank you in advance

There should be a Pollak aftermarket switch valve rated for 65lbs.  Use that.  I highly recommend running in tank pumps on a 87 sending unit.
