Question about 1992 Ford Crown Victoria

1 Answer

Crown Vic Fuel Line

Can I replace a 5/16 inch fuel line on a 1992 Crown Vic with a 1/4 line without constricting the fuel flow. Or does anyone know where I can get an in-line connector that goes from 5/16 inch to 1/4 inch.

I do not recommend doing this.
a 1/4 inch line has a .0491 square inch hole.
a 5/16 inch line has a .0767 square inch hole.
This would result in lowering the flow capacity of the line by over 30%.

You can possibly starve the engine of fuel causing the engine to run lean, which can result in overheating and even worse melting the tops of your pistons in the engine.

Most good automotive stores have many types of brake line and fuel line fittings and adapters you can purchase.

Good luck with your project!

Fuel tank capacity is 20 gallons (US).

Your fuel consumption will be affected by many factors, such as :
- how you drive the vehicle
- the condition and tune of the motor
- driving conditions (traffic, city use, highway use etc)
- tire pressures
- type and grade of fuel used .

It is impossible for me to estimate what fuel consumption you can expect from your own particular car without a whole lot of information.

It's unwise to run the vehicle for long with no working fuel gauge.

2000 Crown Vic cranks but won't start.


Check the fuel pump reset switch again, if it is popped back out then replace that little switch in the trunk, any ford one will do. it works off a magnet and a bearing to close the circuit for the fuel pump. easy fix.

1999 crown vic keeps getting air locked at the fuel rail?


check your fuel pressure
if you dont have enough pressure this will happen
when the fuel pressure is good the system will just push the air out through the injectors or the fuel return line
