Fuel pressure for 94' 454

[Lew45]

Does anyone know the fuel pressure for a 94' 454 stock? I understand it's more than the earlier TBI units (88' throug 93' ). I worked on Cadillacs through the TBI era but they were always 9-13 psi. Thanks.

The 1994 and 1995 TBI 7.4 do indeed run higher fuel pressure; the spec is 26-32 psi.

Thanks. Now I have a 94' TBI for sale. I'm putting it on a 500 Cadillac engine in a 86' El Camino that had a 4.3 v-6 with TBI and I want to use the stock fuel pump. I do have a line on a 88' TBI so I hope that'll work out.
