87 sender & tank pluming for duke is made different & if you have gauge problems is likely NOT the sender cause it.

Pump w/ Low pressure is often Not the pump but crappy "rubber" line in the tank.

2.5 pump only makes ~ 20psi max on system only need 9-13psi.

Leave in if you're doing to swap soon but charge the sock as likely fail because 30+ years make it very easy to wreck working w/ tank problems.

The sending units will work for either engine... but the fuel pumps will not. The 4 cyl has a much lower PSI fuel pump than the V6 does... and it's necessary to maintain normal fuel pressure for the TBI versus the MPFI system. But you can always drop it again and swap out the fuel pump if you need to.

i realized i haven't even tried to diagnose the problem.ive tried three clusters and the fuel guage always says empty.i need to do that.i wanted to grab a sender before rodney shuts down.i hope to do more when the weather in my drive way gets better.

it turns out the rodney sender comes with a new pump.
