Hey I have heard people say that when changing a fuel pump in there Suburban they just cut a hole in the floor board instead of dropping the tank. I have an 87' burb and I'm about to upgrade to the Edelbrock multiport fuel injection made for TBI motors. I have changed my pump before and have no desire to drop the tank. I must put the high pressure fuel pump in for this new system, and I was wondering if anyone had done this before. So if any of you all have and maybe remember how you meassured for you cuts, please let me know.
