How-To Fix 1/3 Tank Stalling Issue

The Issue at Hand:

I had an issue where my car would stall out when I came to a stop or braked quickly but this would only happen when I got down to 1/3 of a tank or less left in my tank. A couple miles after that started, my car would “sputter” during normal acceleration, as if it was running out of gas! (But it still had like 5 gallons left!) This would never happen when the tank was any fuller than 1/3.

While I was searching this site and a couple others for the cause of this issue and for a solution, I saw that I wasn’t the only person experiencing this so I thought it would be a great opportunity to share with others what I discovered and what I did to stop this problem from happening.

My Theory:
I had never taken apart my Fuel Pump Assembly on this car, but have replaced the Fuel Pump on several other Make & Models of different cars so I had a general idea of how they were designed and the parts in the assembly. I suspected that something above the 1/3 tank fuel level had a hole or was leaking and the pump was somehow sucking air. It was apparent that taking out the Fuel Pump Assembly was what needed to be done.

My Discovery:

Aside from the Fuel Pump Assembly Fixture, the only parts to this is the Fuel Pump, a 5/16 hose that is about 3” long, 2 hose clamps, a rubber mount for the lower part of the Fuel pump, and the Fuel Pickup Strainer/ Filter (AKA the “sock”)

What I found was a couple of things:
  1. The Fuel Feed hose coming off the Fuel Pump was a little mushy. It could have been leaking and if it wasn’t, it was probably ready to give way. So I replaced it.
  2. The Fuel Pump was NOT seated all the way down in the lower Rubber Mount. It was about “ higher than it should have been. Not going to work out the math on area or volume, but essentially, this would decrease the amount of available fuel to the Fuel Pickup Strainer. Not enough to cause the issue I was having, but enough to make a difference at the end of the tank. I seated the Fuel Pump all the way down to the bottom of the mount and tightened the hose clamps to the Feed Hose.
  3. The Fuel Pickup Strainer was DIRTY! It had some sort of residue all on it. It was caked on like silt and looked like the color of sulfur. It is most likely the remnants of years of particles separating from the gasoline. Anyways, I put a new one on. It was about $20.
  4. I went ahead and inspected the inside of the tank with a flashlight, as much as I could see while sitting in the back seat and without taking the tank out of the car. There is a baffle in the tank. It’s more of a secondary, smaller “bucket” fastened to the bottom of the tank that has “seep” holes in the bottom so it will fill up when you put gas in, but won’t slosh around as much when you stop quickly or take a sharp turn.

After all that, I put the Fuel Pump Assembly back in the car and reconnected everything. I am now able to drive the car over 320+ miles before having to fill up, where before, the issue would start happening around 220 miles.

The Down & Dirty:
  1. Remove the Fuel Pump Assembly.
  2. Replace the Fuel Pump Feed Hose & Tighten Clamps
  3. Make sure the pump is seated ALL THE WAY to the Bottom
  4. Replace the Fuel Pump Strainer (Sock)
  5. Reinstall the Fuel Pump Assembly and Reattach all Hoses & Connectors

This is what Sulfur or Sulphur looks like and is pretty close to what I saw on the Fuel Pickup Strainer in my gas tank:



Not saying that it IS Sulfur, but that it is a powdery substance that is close to that color.

Let me see if I can upload the pics to my Photobucket. I'll add them here if I can.

Ok, THIS is what the Fuel Pump Strainer looked like when I took it out of the tank:





And yeah, I cleaned that whole thing with a wire brush and some brake cleaner before reassembling and reinstalling it.

Re: How-To Fix 1/3 Tank Stalling Issue

Good stuff tonee. A buncha folks describe your symptoms from various cars. Probably the same problem.

Gonna check my tank. No issues but that screen. Wow. If mine is 20% like that, it would certainly help my old pump with 238k miles live a little longer.

Re: How-To Fix 1/3 Tank Stalling Issue

I think my issue was a combo of all 3 issues. The "Dirty sock", the condition of that Fuel Pump hose, and least importantly, the pump not being properly seated. I think that had little or no effect on anything.

Tomorrow, I roll the dice. I have driven 300 miles on a tank of gas and have been getting 22 MPG. I have a gas can in the car with a couple gallons of gas and I am going to drive until the car runs out of gas. I have been driving under 70 all week! I got up to 80 like 2 times, to get out of sticky situations. I want to see how much of the gas in my tank is useable and IF my Low Fuel light will come on even though my Fuel Sending Unit doesn't work. (My gas gauge stays on Empty and I have verified that the Gauge itself works)

So wish me luck!

UPDATE: I made it to work without any sputtering. I am at 340 miles on a tank of gas. I am about to head home, that's another 35 miles. I'll probably have to fill the tank before heading out for tonights festivities so we'll see how many miles I get before I run out, or the Low Fuel light comes on, whichever comes first!

Re: How-To Fix 1/3 Tank Stalling Issue

I also read that you can have similar effects if you position the Strainer facing the wrong way, but my fuel pump has an alignment stud and so does the strainer so the only thing I had to worry about was the strainer getting folded over when I reinstalled the Fuel Pump Assembly...

Now that I think about it, that could have also been a cause of my problem... But i'll never know... I DO know that the new strainer wasn't folded over when I put it in.

Re: How-To Fix 1/3 Tank Stalling Issue

Final Update: I found out that it IS possible for your Fuel Level Sending Unit to be bad, but that the Low Fuel Level Indicator Light circuit could still be functional.

In short:
  1. I have no indication of how much Fuel I have left in my tank as my Gas Gauge doesn't move.
  2. I verified that the Gas Gauge itself works, using the Electronics Troubleshooting Guide.
  3. Troubleshooting has shown that the problem is the Fuel Level Sending Unit.
  4. The Low Fuel Level Indicator Light works independently from the Fuel Level Sending Unit.

NOW... To see if I can repair the Fuel Level Sending Unit. I'll post another thread on that once I get it fixed! Or if I find a place that repairs them or sells repaired/NOS ones as I haven't found a place that sells them since they are discontinued.

Welcome to PZ! And congratulations on your first post!

You SHOULD have made your own thread, but it's kool... You don't know any better...

Here is a link to some info on Shift Cables and such on a B21A1. You should play around with the Search Function in here. It WILL come in very handy.

Here's the link:

91 2.0 to 90 2.1 si??

I hope this helps!
