I am trying to replace the hose to the gas tank and I am not sure where they are suppose to hook up.


Do you mean the hose on the filler neck? Or the lines from tank to engine? You will need skilled help to do the chassis fuel lines as they need to be fitted correctly and may need special tools to make the connections.

Purge tvs


Most likely a purge Thermal Vacuum Switch. The vacuum switch part will have at least two vacuum hoses connected to it. The bottom portion is a threaded brass fitting with a sealed copper-wax pellet (like a thermostat) that screws into the water jacket of the engine. When the engine gets warm, it allows vacuum to be passed from the source hose to the control hose.

The pump has an inlet and an outlet. To find the inlet (coming from the tank), hold your finger over the openings and have someone crank the engine over. The fitting that has suction on it is the inlet-hose from tank goes there. The hose to the carburetor goes onto the pump's outlet fitting (with clamps).

Although check engine light is on, got a p0442 code, I gotta pump the gas pedle alot while starting it up. Is this common with this code, or a seperate problem?


code p0442 refers to evaporative emission system--small leak detected Possible causes---hose connections---intake leak. EVAP canister---EVAP canister purge valve. I don't think the two are related as you have a efi system and no accelerator pump on a carby. so pumping does nothing. Go back to the fuel pump and check hose fittings and anything else you have altered

The cruise control in my 1989 305 v-8 pontiac firebird doesn't stay engaged. it will hold cruise , but after a few miles , it disengages.


The older vehicles used vacuum to control the Cruise. Check for a leak in the vacuum system. Using a can of starting fluid, spray the vacuum lines and fittings lightly. If the engine revs up after a spray, it'e most likely the leak.

You need to do a fuel pressure check.. You will need a special fuel gauge and the appropriate fittings and adapters are needed to properly test the fuel pressure.

1. Relieve the fuel pressure.
Remove the fuel pump relay form the Power Distribution Center (PDC) Start the engine and run until it stalls. attempt restating the engine until it will no longer run. Turn the ignition key off. Disconnect the cable from the negative battery terminal. Replace the fuel pump relay in the PDC. Any if you get any trouble codes at this time you will need to see a shop to have them cleared.

2. Disconnect the quick-connect fuel line fitting fuel gauge into the fuel line using the appropriate T-fitting and adapters.

3. Start the engine and check the pressure on the gauge, your reading should be 49 PSI with the pressure with the engine idling.

4. if the fuel pressure is not 49 PSI:
1) if fuel pressure is higher you could have a pinched of clogged fuel return hose of pipe. if the line is not obstructed check the fuel pressure regulator.
2) if fuel pressure is lower check the fuel filter, look for a pinched of clogged fuel hose between the tank and the fuel rail. check the pressure regulator for malfunctions. Look for leaks in the fuel line.

Hope this helps.
