so i guess ill introduce myself and hopefully be on here in the future. my names Ben and im hopefully picking up a 98 yukon tomorow, only problem is no motor or trans. luckily i happen to have an 89 sierra with wiring problems but good motor/trans. my question is will the tbi fuel pump assembly swap into the yukon tank. basically i need to know if the pump openning is the same. i know in the end ill have to find out myself but just looking for some hope right now. thanks for the help.
