the screen is not in the sending unit. the sending unit if for your fuel gauge. the pickup tube is where the fuel comes from. it should un thread from the tank. make sure you use thread sealer when you put it back together. how did you make out on your waterpump thermos?

Waterpump no problem, thermos have not attempted it yet. The two outside bolts look tough.

Is the screen at the top, or on the bottom of the tube? In other words where the nipple with the hose barb threads in, or the fitting it self that the barbed part threads into?

it's not hard you need stubby wrenches, a deep socket set and a prybar

you need to unthread the square block from the tank itself. take out the hose barb and then you can get a wrench on the other part. should be 9/16 for the hose barb and 7/8 for the tube. the screen is usually at the bottom of the tube

If the bulb is collapsing you are:

A) pulling a vacuum on the tank as the vent is clogged, this could be temporary cured if you open the fuel fill and allow air inside. (be careful no water gets in there)

B) as mention, your pick-up is clogged with tank corrosion stuff. If you have a fiberglass tank and an older boat, this is most likely your problem. This could become a chronic problem. If so, take off the screen on the pick up, and put a pair of RACORs on board with a lever switch so you can change the filter on the fly and change the cartridges several times a season. (then consider selling the boat or changing the tank to AL)
If the tank is AL and it is old it could also be the problem. You will need to open the tank, inspect and de-fuel it. (filter the fuel out and put it in your truck)
Ethanol has caused more marine fuel tank problems than you can count.

C) maybe you just got a bad batch of fuel with bunch of crud.


BTW, if you have fuel injectors, you DO NOT want this crud to reach them!! You might be looking at more serious repair expense. Keep that fuel clean.

That crap was on there good, the wrench stripped the barb, so I put a vice grip on it and it snapped off at the threads, then I got the tube out.

Bad news is no screen on the end of the tube it was cut like a birds mouth. I am going to get a new tube and barb I am going to run out the rest of the gas on the muffs a little here and there every day, then maybe pull the sending unit and try and look in and get out any debris. I also changed the vent, the old one was corroded , but clear of debris, I will also blow out the hose with a compressor while I am at it.

Isn't boating fun?

Upon further inspection of the pickup tube I found something, the screen was at the top of the tube, when looking through it towards a light there was very little light shining through.

So I took the old tube apart and this is what I found, there was some stuck in the tube....
