Best EFI Conversion gas tank

Spectra. You won’t be sorry. they are Cost effective and you can use OEM style hangers and pumps.

Here are some better pictures. The older and terrible after market with the "pie plate". Avoid this style.

The current Spectra that duplicates the OEM GM baffles. This is the style you want.

Here is a better pictures of the original 84-87 Turbo Buick baffle. Again, the original GM Turbo Buick tank is still probably the best internally baffled tank.... if you can find one.

I got the spectra tank. Going to set it up for twin Walbro 450 pumps with a custom hanger and 0-90 ohm sender.

I just finished up the spectra GN tank in my Cutlass. I had my neighbor weld a Cutlass fill neck on which lined up perfect behind the plate. I put a Aeromotive stealth 340lph pump on the GN sending unit, and can't even hear the pump while engine is running. Did a quick rip yesterday and it works great.

My '86 T-type had Zero plastic baffles in the tank. I replaced the original fuel pump and took pictures when I replaced the tank in 2017 - No baffles. 86' and '87 Turbo Buicks had completely different Fuel tanks/fuel pump set ups so likely '85 and earlier cars looked like my '86. My '86 tank hanger still had the expansion thingy in the fuel line that was for the "water hammer" effect batch fire had on the fuel line.



It did have a mid tank divider wall so it did not starve the pump under acceleration, but aggressive off ramps at less than 1/2 tank would stall the motor

For the spectra replacement tank I bent the lips of the baffle bowl in with plyers.

I also removed the restrictions in the new sending unit/fuel pump hanger,

by removing the neckdown with my $10 HF cut off wheel. I also opened the outlet so it was full 3/8"

Sounds good. Your idle on YouTube popped up and I liked it but you don't allow comments.

Hmmm, odd. I didn't select "no comments"
