BTW, on this particular application I was guessing since every house payment making fuel pump replacement I've done has has tank baffles.

I do that too from time to time. The kids screaming the wife yapping, it kills the brain cells that make me care lol
Sorry Nathan, the last couple hundred I have messed with, I guess some one stole the baffles out, because I have never seen any...I can take some pics of some tomorrow. I have atleast two 88-98 tanks and six 99-09 tanks and a few ford tanks too....
Wow.....semantics? What are you calling a baffle? Had three out today, two 07's and an '09. Did a resecure on a 1990 Suburban a couple weeks ago. Devilles from 85-93 are known to have them come loose and make the gauge read wrong telling the driver there is more gas in the tank than there really is....causes stalling on turns....

The pair of 87 tanks I've looked in to did. Any reputable parts supplier will sell tanks for the 73-81 model years, 82-86 model years, then an 87 model year fuel injection specific tank. The 87 tanks have a "cup" or "bowl" or "baffle", whatever you want to call it, around the pump to keep fuel held close to the pump.

yeah, both my 92 and 93 had the plastic baffle. Once they crack you have fuel starvation problems with less than 1/2 tank. My 92 was awful, the tank was toast. My 93 isn't much better.

This is the "Baffle" or Fuel Pump Reservoir in a 1987 EFI pick-up truck Gas Tank. 1986 & Older tanks don't have this in them. Although the tanks look the same...They're NOT.

Another 87 tank, this one is from a board members truck at 67-72chevytrucks.com that converted his 86 to TBI with parts from an 87 donor truck.

Here are two tanks that I had laying around in the back one is a 99-06 plastic and the other is a 88-98 tank, not sure on exact years. We do alot of fuel cells. No baffles in these
I am baffled how long this thread is
