Fuel filter 1996 buick 3800

Sounds more like a worn out fuel pump that binds up

The fuel filter if totally clogged, would drop pressure
& it would be slow to get from 20 to 50 mph,not the
problem I don't think.

You do not change parts to see if that will solve something

You surely know if the filter is over 4 years old

Your Exhaust Conveter if origninal ,problem or not
is totally shot,they only last 12 to 14 years.

You have to check the TPS Sensor & may other things

I hope you don't just go years until your break down,
because the car has been good to you

That makes diagnosing things more time consuming, as you
have no preventative maintenance history
I would have a fuel pressure gauge put on it

96 buick skylark runs about 3 seconds then dies.whats wrong?

Fuel pumps don't slowly go out, they either work or they don't. I recommend replacing the mass air flow sensor, which is the square metal piece that's mounted in the middle of the big air tube that runs from the air filter housing to the intake. I replace the front head on mine and during the reassembly, I forgot to plug the wire back into the MAF sensor and had a similar problem. I would have it tested first if possible. If u have any other questions abt this car, feel free to send em to me directly, especially if yours has the 3.1 V6.

We replace fuel filter but its leaking so can we replace just a section of the fuel line? And is this a hard job to do?

You can change a section using a pipe cutter (to cut out the section) and use "compression unions". Bring a piece of the fuel line to the automotive store and ask them for a piece of line and Compression unions. These unions just slip over the lines and tighten on them for a leak free fit.

I cant find my fuel filter on my 91 model landcruiser 4 litre petrol

Hope this helps, it it does please leave feedback and vote Thank You and Good Luck

  1. Locate the fuel filter in the right rear portion of the engine compartment.
  2. If vehicle has been operated within an hour, the fuel system is probably under pressure and requires caution when removing filter union bolts.
  3. Slowly loosen the filter union bolts. Some gasoline may escape, so ensure that the potential for fire is minimized.
  4. Remove the union bolts and four gaskets.
  5. Loosen filter clamp and slip filter from clamp.

Which way does the fuel filter go on a 84 buick

One end will have a hole, that's the end that goes in first.

Fuel line broke leading from fuel filter how can I fix it?

Measure the outside dimension of the line and head down to the auto parts store. If it is rusty where it broke you need to get a piece of fuel line with enough length to bypass the weak spot, usually 2 or 3 feet. Make sure they give you fuel line and not brake line. There is a difference in thickness. Also get 2 compression fittings the same size as the line and some emery cloth and a small tubing cutter.
Cut out the bad piece of line, on a straight section, and clean up the good ends with the emery cloth so the ferrules will slide on easily. Put the nut on first, then the ferrule and the the union. Withthe line butted snug in the union slide the ferrule in snug and tighten the nut. Don't overtighten, it's easy to wreck your joint. Do the same with the new piece of line. Start the car and check for leaks. Tighten nuts that need to be tightened if it's leaking, and you are done.
You shoul be able to do this for about $20-$30. Hope this helps.

How to change a fuel pump yourself tip?

The fuel supply and return lines are probably in bad shape, I'd recommend replacing them with the neoprene fuel line replacements, with the quick disconnect, first replace your fuel filter( it's located on the drivers side rear near the rear wheel looks like a canister in the line) again the quick disconnect lines can be used here, it will make your life easier later, these are available at most autopart stores along with the union pieces to run new lines, you can buy the quick disconnects for about $20.00 for 18 inches of new line with the quick disconnect clip on one end and the union pieces to put the line back together. Make sure the fuel tank is near empty, unhook fuel lines from the tank loosen the straps enouph so you can reach up and unplug the sending unit, now carefully loosen the straps( be careful with the straps they can be reused) until you can work the tank out, remember you need to be careful of the fill tube, if you damage it you will need to wrap it in rubber hose more unecessary work if you are careful. BEFORE YOU DROP THE TANK CHECK THE FUSEABLE LINKS, they are only a couple bucks, ALSO REPLACE THE FUEL FILTER 1ST. these items are cheap and could be the cause of your problem, the fuel pump runs about $100 but the work involved is dirty and not fun. Before proforming any repairs like this on your own make sure the vehicle is safely secured on jack stands, the rear has to be up quite a bit to give you room to work under the car. The fuel lines can be very time consuming, but will save you time when you are putting the tank back in after replacing the pump, and heaches down the road.

Can't figure how the union part is suppose to go

You might be talking about a fuel line, quick disconnect connection. If so the tool looks like a mushroom with one side cut out. There are a few different styles out there and you can pick it up any part store. Just ask for a fuel line quick disconnect tool. When you insert the tool it will spread the three metal tabs so the lines can be seperated.

Fuel leaking

If it's a 4.0 engine, the filter thing is the fuel pressure regulator (does it have a vacuum hose going to a fitting on the intake manifold?) Depending upon how much material (clean tubing) you have to work with the temporary"fix" is just about the same as the real repair. Cut the line, removing the failed part, and install a new piece of steel tubing, using crimp type unions (they have brass ferrules on both ends that seal permanently to tubing once they are tightened. Sometimes you need to remove a decent length to get to a straight clean area (unions are not recommended to be used on curved sections of tubing.
Or, if you can't do this, cut the tubing right over the leak, slip a piece of high pressure fuel line (rubber) over both ends and fasten with two clamps (made for fuel lines, not for water hose applications) Make sure that rubber hose extends at least one inch past the leaking area.That will get you to a shop! Check the regulator. it's doubtful that both the line and reg are leaking.
Good luck
