2002 Buick Rendevouz leaking fuel after changing fuel pump

We changed our fuel pump, and got our car running again. However, the first time I filled up the tank, small amounts of fuel would leak out under the vehicle. We are not even sure where it is leaking from. We just know that the puddle is under the gas tank. It did not do this until I filled up the tank. Any suggestions?

    I have noticed another thing with this leak that really concerns me. It does not appear to leak gas while it is being driven; however, after it has been parked for a while, the whole car starts to smell like gas, especially the engine. Does anyone know what can cause that?

Check and see if there is still a leak when you are not putting gas in it if it is still leaking, lower the tank and check all the hose connection for leaks. replace hose and clamps turn key to run but not start with tank lowered look for leaks

I suggest replacing the fuel filter first before taking on any more expensive solutions. I had those same symptoms with my '95 LeSabre and that was the culprit.

YOU NEED TO REPLACE THE BELT TENSIONER.
IF YOU BUY THE CARTER BELT TENSIONER AT ADVANCED AUTO, IT COMES WITH: A PLASTIC ELBOW WITH O RINGS, TENSIONER, PULLEY, NEW O RING WHERE THE BELT TENSIONER MATES TO THE ENGINE BLOCK AND NEW O RINGS FOR THE INLET AND OUTLET CONNECTIONS ON THE BELT TENSIONER TO THE HEATER CORE (COST $72).
IF YOU DON'T REPLACE ALL THE ABOVE O RINGS THEN YOU CAN EXPECT MORE LEAKS.
IN ORDER TO REPLACE THE PLASTIC ELBOW YOU MUST REMOVE THE BELT TENSIONER ANYWAY. IF THE BELT HAS SEVERE CRACKS REPLACE IT ALSO.
STEPS:
-REMOVE BELT
-DISCONNECT BATTERY
-DRAIN ANTIFREEZ AND DISCARD
-REMOVE ALTERNATOR
-REMOVE BELT TENSIONER
-REMOVE PLASTIC ELBOW (DO NOT ALLOW BROKEN PIECES PLASTIC OR DIRT TO GET INSIDE THE ENGINE WATER CAVITIES.
-CLEAN ALL CONNECTION WHERE O RING WILL MATE.
-TO REASSEMBLE GO IN REVERS ORDER
-REFILL THE RADIATOR WITH COOLENT 50% MIX USE THE 5 YR GUARANTEE TYPE.
-MAKE SURE THE COOLENT RESERVIOR IS
FILLED TO THE HOT LEVEL MARK.
-RUN THE ENGINE UNTILE IT IT REACHES THE 1/4 % TEMP MARK ON THE TEMPERATURE GAUGE THEN TURN THE ENGINE OFF AND OPEN THE BLEED SCREW ON TOP OF THE THERMOSTAT HOUSING.
ALLOW THE AIR TO EVACUATE, YOU WILL SEE COOLENT COME OUT THEN CLOSE THE BLEED SCREW.
-BE VERY CAREFUL WHEN YOU OPEN THE RADIATOR TO REFILL TO THE TOP.
-REPEAT THIS ONE MORE TIME.
-RUN THE ENGINE AND KEEP YOUR EYE ON THE TEMPERATURE GAUGE' IF THE TEMPERATURE GOES BEYOND THE 1/2% MARK, SHUT DOWN THE ENGINE QUICKLEY AND LET THE ENGINE COOL.
THIS MAY TAKE HOURS TO COOL DOWN BUT THE COOLING SYSTEM WILL TURN FROM PRESSURIZED TO VACUUM AND DRAW COOLENT FROM THE RESERVOIR TO REFILL THE SYSTEM.
YOU WILL NOTICE THE LEVEL DROP IN THE RESERVOIR .

Check your heater hoses. It sounds like your leak is a hose.

SOURCE: leaks small amount of coolant, but I don't see

Check the engine oil, see if the level is going up and what the condition is. you can take the oil cap off and inspect under it. if there is a milky fluid then the antifreeze is leaking in to your engine crank case which is bad for the engine bearing. The other thing to also check is the transmission fluid. make sure that its till bright red and not over filled to make sure it's not leaking in to your transmission through the transmission cooler which is apart of the radiator too. Good luck and keep me posted. Be glad to help.

1990 Buick Century,F.I. was dirty,car ran rough,son,trying to help sprayed carb cleaner on what he thought was a carb,not running at the time,now it needs to be primed to start,can l do anything ?


he was spraying into a throttle body that consists of an injector(TBI). these cars suffer terribly from EGS(ethanol gas syndrome). Do these simple steps. First; change out fuel filter(buy 2 of these-get the cheapest ones you kind find). Buy a can of SEAFOAM when you get the filters. You need to fill tank with as much Premium fuel as you can.<p>
Change out filter, add SF to gas. Keep car running at least 5 minutes on as steady an idle as you can. Drive car hard for at least 2-3 miles. When you get it home; change out fuel filter again.<p>
The fuel and the emission systems should start to get better. One other thing: buy a new PCV valve(probably cost4-6 bucks) replace it also.<p>
Clean out air filter or replace. Do not!, use carb cleaner or ether again. This should be helpng the cleansing process by now. Your car is full of corn liquor by-product and excessive amounts of water. It's in your fuel; your emission systems and your TBI. Your pump may be filled with it, and not have enough Psi to allow the pump to pump properly. In extreme cases, we've had to replace pump, remove fuel tank and clean it.<p>
When this is all done, always add SFoam every 3-5000 miles to prevent this from happening again.<p>
And at times; the crank/cam sensor has to be replaced.<p>
I don't know how much this car is worth to you, but this is simplier than buying an engine.<p>
The worst case I've seen is the ethanol burns a valve and it has to be rebuild. So try this, I think you can rescue it. Good Luck.

Change the fuel filter. If pump is new, and you are not leaking gas from lines, than either the filter is clogged, injector stuck open

Fuel leaking almost poring from under back left seat, under car


If the location of the wet spot was towards the rear of the car by the fuel full hose and as you said the leak stopped as you use up fuel and lowered the fuel level in the tank than the leak is located in the fill pipe area or tank. Next time you fill go under the car and look for the wet spot.
