Hi Mike

I too, would like to find a baffled F.I. fuel tank that would fit nicely into a 67-72 Blazer. I have a 1990 350 looking for home and I thought it might end up in my 72. I do not think however the Suburban tank will fit easily.

Chevrolet Suburban Part Number: GM14C 1986-91 Fuel Tank 31 Gal with F.I.
Capacity: 31 Gallons/118 Liters Dimensions: 28-3/4 X 28-1/8 X 12-3/4 inches
Depth of bottom half - 5-1/2

The 72 Blazer tanks are rectangular
Capacity: 21 gallon Dimensions (my measurements): 28-3/4 wide (side to side) X 18-3/4 long (front to rear) X 14 inches high Depth of bottom half - 7

Apparently the newer blazer tanks are baffled and the same size as the Suburban but not as deep:
Chevrolet Blazer Full Size 1987 Part Number: GM15C 1987 Fuel Tank 25 Gal with F.I.
Capacity: 25 Gallons/95 Liters Dimensions: 28-3/4 X 28-1/8 X 10-3/4 inches Depth of bottom half - 3-1/2 inches

I hope someone knows of a solution for us!

If you are doing a FI swap and just want the tank for the baffling, the other option is to install an in tank fuel pump complete with its own baffle. www.tanksinc.com makes them. That's what I used on mine. The only problem I had to fix was that the upright was a bit too short and I had to put a short extension on it. Otherwise..works great. http://img.photobucket.com/albums/v6...TPI/Pump-1.jpg

I used a tank from a late 90's Tahoe when I did my TPI swap. It is baffled and had the high pressure internal fuel pump for the Vortec engine. All I had to do was swap out the fuel pump for the TPI application.

I have also looked at doing this and what I found was that I would have had to cut the rear frame support out and weld in a new support that had a mounting flange 180* routated compared to the factory support. The reason was becasue the tank would be too close to the rear diff. Also the next cross support would also have to be moved. It would have been easy for me because I could have made it fit with some fabrication but decided not to becasue of the time involved. For sure without modifing the rear cross support the tank is too long it needs to be mounted further back then the factory cross support would allow. As far as the gas fill location being different I felt that it was in a good center point in the tank that the tank could be turned around easily.

Good luck
