Hello everyone im new to this forum and wana say this is Great ....access to a lot of good experiance jus a click away . My time has come to do my fuel pump in my 1988 iroc convertible , have read many post about the fuel hatch , or tank removal . i have no problem cutting the hatch ...the only thing stopping me is ....if the fuel lines at the entrance to the tank are steel , then the hassel of cutting and installing couplings....which my cause stress further down stream on the lines ,which in turn my result in taking the tank down anyways. i have a basic manual and it shows a picture of rubber lines to the entrance . Anyone ever seen this ? could some models have rubber or are they really all steel lines?..... THANKS

 

the sending unit is all steel line until you get to the front of the tank, where you have a foot or two of rubber between the sending unit and the body mounted fuel lines.

To mod the sending unit lines right, you need to either flare them or have threaded fittings installed; something that will take longer to do than dropping the tank. Just cutting the lines and putting in rubber could lead to them blowing off the feed line due to pressure.

 

Personally, I think it is easier to drop the tank and do it right than it is to cut an access hatch, finish it properly, cut the lines, flare them, and seal the hatch back up to the car. It's just time consuming and too much of a hackjob for me.
