Black_Baby Posted March 13, 2015 Share Posted March 13, 2015 Could one replace the fuel sending unit from inside of the car by making a hole/window through the floor? It would eliminate the need to drop the tank which would be nice. How crazy is this idea? Link to comment Share on other sites More sharing options...
Guest Corvanti Posted March 13, 2015 Share Posted March 13, 2015 having had to replace the entire fuel pump assembly, and looking at that as a shortcut - IMHO - heck NO!!!BTW: if you have to replace any part (like the sending unit), i'd strongly suggest replacing the entire assembly. dropping the tank is not something i'd want to do (or if you have to, pay the labor charge) again in the near future.here's some fuel pumps, etc: http://thereattastore.com/fuel-pumps/ Link to comment Share on other sites More sharing options...
2seater Posted March 13, 2015 Share Posted March 13, 2015 I have toyed with that idea for a while now. I do not know if it is practical in this instance but there are some vehicles that do have a hatch to access the top of the tank. I know the reason I have thought about is due to the condition of the supports and other associated items that would be disturbed while dropping the tank. There is no doubt dropping the tank would open a whole new can-o-worms. To be clear, this is only considered on a somewhat derelict car, that is in poor shape underneath.

Ronnie Posted March 13, 2015 Share Posted March 13, 2015 If corrosion is a concern when installing a new pump it might be better to put the new pump in a new tank and install it with new straps. All are available in the Reatta Store for a little over $200 bucks. It might be faster, easier and cheaper in the long run than cutting holes in the car. Just my 2 cents.

Guest 89 Maui Posted March 14, 2015 Share Posted March 14, 2015 If you are contemplating changing out the tank and hangers I would like to give some additional info. The '88 & '89 have steel fuel lines and are highly subjected to rust. In the '90 & '91 Buick changed to neoprene fuel lines probably due to the rust problem. I found a '90 being parted out and I changed out my rusted fuel lines on my '89 for the neoprene lines, a direct swap and I am pleased that I did.Woody89 MAUI Link to comment Share on other sites More sharing options...
