    Sorry for my last comment--air hammer/chisle is tool I'll be using--car is stuck in driveway on top of snow and the tank is 18 yrs old---I don't want drop such an old tank--we all know what happens when that is done.

  • kenwilinski Jan 24, 2009

    proper prep is key--cold weather keeps the fumes down( if any)--water spray will eliminate sparking--I only need to pull unit through to motor--wire it up to hold in place and replace motor--harness will be replaced also--those connectors can be a problem from the winter salt.

You don't cut an access hole. You have to remove the fuel tank.

    I may well be, but I do know that there is minimal clearance between the top of the fuel tank and the bottom of the floor board under the rear seat. So obviously one should not use a torch (open flame near gasoline) and I would not recommend a saw or grinder (sparks near gasoline). The chances of actually cutting an access hole without causing damage to the tank, the tank sending unit or yourself are relativley small. Also removing the tank in order to service the fuel pump is quite simple and only takes about an hour out and about an hour in.

  • steven_e55 Jan 24, 2009

    I do not envy you predicament. I checked on just how big the sending units are and of the two possibilities I am not sure if either can be removed from the top side due to the lengths of the lines. I think I have given you the two links to the sending unit pictures but we will see. 25027211 and 25027568. If not you could look up application at www.acdelco.com Maybe the pictures can give you some idea of what may be your best approach. If you do decide to use an air chisel remember these too will produce sparks that given the right circumstance could be tragic. Is there any chance of clearing the snow from under and beating on the tank while someone tries to crank the vehicle? This may work to allow you enough run time to move the vehicle to a better location.

I have a scratch plate in the way of replacing the fuel pump and I dont know where the acess panel is to get the plate off. where is the acess panel or how do i get the scratch plate off?


Year make and model helps. The plate has two bolts. Most times I have to cut or break one off. I never put the plate back. You do have to drop the tank to get the pump out. I remember this. It didn't last long.

Where is the fuel pump of a 1993 Honda Accord Ex located


You must drop the tank to change the fuel pump. There is an access panel, but not big enough to remove the fuel pump. To do that, you must cut/enlarge that hole. Hope this is helpfull

Inside the tank fuel pump


You can not get to the fuel pump from inside the car. I have a 91 you have to drop the tank. BUT if you just have to. you can cut a 8in by 11in access panel in the center of the hump above the tank. You will need to use a non spark cutting tool like a air hammer. You will need 3 brass fittings 5/16 in I believe. (This is just an idea if you have to do it this way). I am not giving you this as advise. Just you could do this if you want to. Cut the hole so you can access the fuel pump from inside. You will have to cut the fuel lines one at the time. cut them in different locations from each other so the fittings will not interfere with each other. (room to fit and tighten these fittings) The fittings you will need are called compression. They are brass have small rings that fit over the line and compress to seal it. Once you cut your hole cut your lines remove the pump lines all as one part it takes a little finesse to get all out. Make a good fitting cover for your access hole and thats that. Clear as mud? this is just a (you could do it this way) but its not the right way. Drop that tank out the bottom take your rear end loose from the shocks, pull your exhaust hangers loose and let the muffler hang take the tank band loose get as much fuel out as you can. Jack the rear of the car up 3 1/2 to 4 1/2 feet to get the room needed to get the tank out. It is a tight tight fit be sure the car is secure because you will be pulling and jerking pulling and jerking to get the tank out. Work slow and careful.

Can I cut a hole thru the trunk to access fuel pump?


If you can do it without damaging anything. it is all up to you. I would make sure to seal it back tight after cutting the hole. Don't use anything bit a chisel. I have never seen it done but it's your car.

Fuel cut off switch for 1990/91 ford escort 1.9


The "inertia switch" which shuts off fuel to the engine in the event of a collision or jolt on a 1991 through 1996 models, as well as on 1998 coupes, is located in the rear of the vehicle, near the right (passenger's side) strut tower. On sedan and coupe models, open the trunk and remove the right-sided trim panel. On sedan and coupe models, open the trunk and remove the right-side trim panel. On hatchback and wagon models, there may be an access door secured by clips. On some models you may need to remove the lower quarter trim panel on the right side, however it is easier to cut an access hole directly above the switch.
