1987 GMC fuel sending unit

[nascarmikeb]

I have a 87 gmc pickup original engine was 305 tbi. I now have a 350 carburated I am going to install. I'm trying to figure out the best way to make this conversion. A 1985 sending unit has a completely different connector than does the '87. I am using the standard fuel pump mounted to the engine block. I have removed the in tank pump. I want to be able to use existing truck sending unit wiring with a sending unit that doesn't have an in tank pump like those from 1985 and earlier.
Is this possible?

Thanks

Mike
