If you've ever removed the fuel block from the fuel rail it is extremely common to see a badly deteriorated gasket there. This gasket is one of the most neglected maintainance items on the Fiero V6's and if it fails a fire will result. Its one of the first things that we replace when working an engine replacement job. Our stock of these is down to the last one and a new source is needed. Trouble is that any replacement seal must be made to hold 50 psi of fuel pressure. As long as the Fiero Store seal holds the pressure it should work. Its a high price for a small seal plate but the genuine GM item was never cheap either.
