Giday mark there may be a filter inside of fitting which fuel hose/s attaches to it'll be a fine mesh if it's there. It's unusual for there to be a ball before the needle and seat unless it's to restrict fuel return line.
It's also possible that the needle is worn to the point where it jams in the seat in which case it'll need replacing

What is the best way to drain my fuel tank on a 1967 karmann ghia see i can replace the fuel tank tube filter


I drained mine by unbolting the entire tank (only 4 bolts on top) taking it out and inverting it for drainage.
BUT, here are two shortcuts that I realized later:
a ) You can get get under the front hood beneath the car (not easy to reach) and unhook the main fuel line from tank to engine.
b) The easiest way is just unhook the fuel supply line from tank to the carb and drain it slowly and best if parked at inclined level for better drainage down the hill. Collect Fuel in a fuel container.

Where is the fuel filter located on 1989 chevy astro van


Fuel filter is inside of Frame rail under vehicle. You can slide underneath the van and look up at the floor where it meets the inside of the rails that run paralell to the sides. It is the shiniest thing up there. I can't recall if it under drivers seat or passengers seat. The filter unbolts from the frame by loosening a clamp. The filter is unhooked from the fuel lines by using two wrenches one to hold the nut at each filter end still and the other on the nut on the fuel lines to turn and unscrew the fitting. Make sure there are no open flames nearby or hot bulbs you can splash fuel on when you unhook the lines. You will spill some fuel. You can stick a sharpened pencil in the line from the tank when it is disconected to stop fuel from pouring out. Make sure to stay as far away as you can and wear something to protect your eyes from splashing fuel when the lines are unhooked.

Very slow to fill fuel tank. refuel hose nosel keeps clicking off when refueling


on your fuel tank their is a vent line from the tank that comes back up to the main fuel inlet line that is to let the air from an empty tank escape while fuel goes in, if that vent is not working properly then the fuel cannot go in quickly because the air in the tank has no where to go. The hose is made of rubber and may have become fatigued and kinked on a sharp corner. You will have to go underneath the vehile and inspect where vent line from where it exits the tank and goes back up to the main inlet line. You may have to replace the line.

How to change fuel filter on 1996 Honda Civic


It is located Under hood, center, upper firewall, mounted in fuel line (basically back of dash). Take note of how it is mounted not to install backwards. Unhook battery ground. Unhook two fuel lines one on top one on bottom of filter.Mark fuel lines top/bottom tape helps not to get mixed up. Remove from clamp. place new filter in clamp noting proper top and bottom. replace fuel lines. reattach battery, cycle key on and off 3 times slowly.

I have managed to mix up the 2 fuel pipes that connect onto the sender/pump unit on the fuel tank of my ford escort mk6, one is marked red and the other is white where does each pipe go to so I know I have...


they should be diffrent sizes, the bigger one goes to line that also goes to fuel filter which is the feed line (preasure line ) the smaller is the return, which is a metal line all the way to engine, if they are exactly the same size then unhook both have someone quickly turn key on while you watch the line that sparys fuel, that will be the line that the fuel filter is on that the way to check it, good luck.

2000 blazer 4.3 hard to start (fuel problem)


Do you have the fuel tester hooked the in the overgrown air valve on the fuel rail in the back of the engine? Or do you have the fuel line unhooked in the back and hooked to the pressure pump? You want the fuel pressure to be in that 60 lb range so if you are hooked into the pressure valve on the fuel rail allowing fuel to go through, then I am betting it is the fuel pressure regulator. To get to that, you have to take the throttle body off and take the plastic plenum that covers the injector packs. On the back of the mount where your six pack of injectors are sits the pressure regulator. If it is faulty then it is dumping fuel instead of holding the pressure like it should.
Get a Chilton or Clymer manual and it shows you in pretty good detail how to fix it. I've done it to my 98 S10 with the same engine.

If you unhooked the fuel line so you are losing pressure from the line back to the pump then I would say your pump is letting fuel back to the tank when it shuts off. My money is on the first possibility though.

Good luck
