Fixing the Gas Smell in the Trunk of an Alfa Romeo Spider, part 2

This is International Auto Parts Fixing the gas smell in the trunk of an Alfa Romeo Spider part 2.

Day 1 Session 2:
It has been about a week since we replaced the vacuum lines in the trunk. We are still having the gas smell, but it is not as bad. So this means that we fixed part of the problem, but it is not completely fixed yet. We have narrowed the problem down to the left side of the trunk where your gas fill and fuel supply line to the engine is at. So we are going to pull the floor carpet back and remove the trunk gasket again to pull back the side carpet.

We are going to be working around where the fuel pump and sending unit is located in the floor. We are going to remove all 6 screws and the washers that are under them. You then want to pull the wires off the top of the sending unit, but mark them so you know where to put them back. The black wire which is your ground goes on the bottom left fuse link. The purple wire which tells how much fuel is in the car attaches to the top left fuse link. The Pink wire with the white stripe which is power for the fuel pump attaches to the top middle fuse link. The white wire with a black stripe which is the indicator for the low fuel light on your dashboard attaches to the top right fuse link. Once disconnected you want to just pull them out and tuck them out of the way for now.

We are now going to try to get the sending unit out with the fuel pump on it. We are going to pull the supply hose off to give us some room to work. Tuck the fuel hose up so that it is propped upwards so that you don't have fuel running back out. Gently pull the sending unit and fuel pump all the way out. The gasket doesn't look to bad, but we will go ahead and put another one on it since we already have it out of the car. (Looking at the fuel pump on this car it is not an original, but aftermarket pump. The ones we sell do not look like this exactly, but we are going to leave it since it seems to be pumping fuel.) The gasket just slides down over the body. The sending unit though is original you can tell because of the basket bracket. The ones that we sell do not have that piece it just relies on the hose to make the connection to hold it all in place.

While we have the pump out we are actually going to go ahead and pull the screen out since we don't think it is doing much filtering. The screen is actually just something someone has put in there. You can see what remains of the original filter and it is actually broken apart; so we will go ahead and put a new filter in that will be the correct one. You don't need to put the bracket back on since the hose should hold it fine as long as it is in good shape, but this hose doesn't appear to be. So we will replace this as well.

Day 2 of Session 2:
We found a couple things wrong that we had not expected and you don't know till you are in it. When we put all the parts back in we are going to use the basket piece just so that it keeps the original look. We did find something else after we removed the sending unit; which was the float had gone bad and was full of gas; so we replaced that as well. We already have the new gasket back in place and we want to make sure we push the five screws through it so that we don't lose them in the gas tank. When we put the replacement hose on we want to make sure the 13mm side attaches to the sending unit and the 8mm side attaches to the fuel pump. There are no clamps needed it just slides into place and held by friction. Then we will reattach the bracket and a hose clamp is all that holds that into place. Finally we will put the new filter on which just snaps to the bottom of the pump.

When placing the fuel pump and sending unit back in it is important to have it in the correct clock position. It will fit any way, but will only work one way. When putting the pump back in you want to position the float so that it faces the right side of the trunk and then as it goes in the float arm is directly at your spare tire. You will need to mash the filter in as you put the pump in, but it will fit. Try to make sure on your gasket the largest hole is aligned with your fill, it help you align the rest of the holes up. Once the sending unit is back in place reinstall the fuel hose and the wires from earlier.

Aside from the fuel pump parts we replaced we also found that the carpet may have contributed to the smell. The carpet had gotten fumigated so we have pulled it out and are letting it air out. We think that this will fix the problem.
