Fuel pressure on a TBI

How much fuel pressure is there on an 87 with TBI? It has an elect fuel pump. The fuel hose under the truck has regular clamps on it. And the hoses are very old.

Re: Fuel pressure on a TBI

Mininum is 9 PSI to run. The higher the better. Replace the hoses if they are in bad shape.
