    I posted TBI spring pressure information here: http://www.gearhead-efi.com/Fuel-Inj...rings-Measured

    I think the one listed on Ebay will do the pressure your looking for: http://www.ebay.com/itm/GM-TBI-Fuel-...item3cdceec9e7

    I can't find the thread right now but a member here had made a bench pressure tester with air and went through the MCJ? Catalog and found all the right springs...
