What is the fule pump specs on a 88 454?

There isn't a single definitive fuel pump spec for a 1988 454 engine. The specifications depend heavily on the *application* of the 454. Was it in a truck, a boat, an RV, or a car? Even within those categories, different manufacturers and trim levels will have different requirements.

To find the correct fuel pump specifications, you need to:

1. Identify the exact vehicle: Make, model, and year are crucial. Even the specific trim level can make a difference.

2. Locate the original fuel pump (if possible): The pump itself will have part numbers which can be used to find replacement specifications.

3. Consult a parts catalog or repair manual: A shop manual specific to your vehicle's year, make, and model will list the correct fuel pump specifications. Online parts stores (like AutoZone, Napa, etc.) can also help if you input the correct vehicle information.

The specifications you'll be looking for include:

* Flow rate (GPH or LPH): Gallons or liters per hour – this indicates how much fuel the pump can deliver.

* Pressure (PSI): Pounds per square inch – this indicates the pressure at which the pump delivers fuel.

* Electrical requirements (Voltage and amperage): Most likely 12V, but the amperage draw will vary.

Without knowing the specific application of your 1988 454, I cannot provide the correct fuel pump specifications. Attempting to use an incorrect pump can damage your engine. Always consult your vehicle's documentation or a reputable parts supplier.
