so your fuel gauge doesn't work on either tank?
define "messed around with FSV (fuel selector valve)" ?
how much fuel is in each tank?
have you tested for voltage at the FSV?
you can bypass the FSV pretty easy.Just hook the front tank up directly and see if it runs fine.if not,you may have a bad pickup in that tank.hook up the rear tank and try it again.
if it runs fine hooked directly to both tanks(one at a time of course) then you found your problem= bad FSV.either replace it,or just use one tank.

ahh.the FSV is very low pressure rated.it can't handle more than a few psi.you may have blown it by blowing in it.
if you get a new one.don't do that again.don't want to ruin a new one just so ya know.

yeah sure.you can.as long as you can find a place for it under there,and comes with a pick up.needs a feed/return line/and vent.
stay away from one with an in tank high pressure electric pump,or you would need a regulator/block off plate for stock lift pump/high pressure rated fuel line/new electric lines to feed it etc.
if you bypass it to test,and see its faulty.its pretty simple and low cost to just replace it.for more info see here:

but test for voltage and bypass it first before just replacing it,as it may not be your problem of course.

hmm i dunno.im sure some guys have done it.i wouldn't think the tank up on a bed would be any problem.i would think the lift pump could handle that without issue.
you need a return line to it of course,as the fuel is used to cool the injectors/ip pump in our systems.
if pumping this high on the return would be an issue(again,i really doubt it),im sure someone will chime in.

take a rag soak it with gas and put it over the intake filter( gas works even better than either), if you can get it to fire its a fuel pump( probally a mechanical fuel pump depending on your year), injector problem, or CPS crank position sensor, if the computer dosen't read this it will not deliver fuel plus they are notorious for going out from what i'll seen
