grand national sending unit

[TexasT]

Hello everyone i have a question about the sending unit on the grand national .
I have a 87 ls with the 4.3 tbi i was wondering if the grand national sending unit will work on my monte i see gbodyparts.com sells them for the 4.3 monte but for 200 plus. and the grand national sending unit is only 87 dollars on rockauto.com since the grand national one has the same 3 pin connector as the monte

If less expensive is what you want this one is less, but doesn't include the wiring to the pump. But you can use bigger wire to power your pump.

You could order up one of these to get the bigger wiring.

they also have different fittings if you have a different plug
