An oil furnace pump is one of the many components that you will need to keep up with. Each one has its own job and will over time probably have to be replaced. With the proper maintenance to all of these parts you will find that replacement is something that you will not have to worry about as often. However, regardless of how much maintenance you do and how good you are to the parts you will still need to worry about how to tell when one of them needs to be replaced. Doing it yourself will be able to save you quite a bit of money in the long run.

Step 1 – Know When to Replace

It is always a good idea to do some routine maintenance on your furnace pump strainer whenever you are checking on your oil filter. This is typically done either in the beginning of the heating season or midway through. It is always recommended to do it in the beginning in case work does need to be done you will not have any cold nights in the middle of winter. If your strainer appears to be badly bent or torn in anyway, then you will need to replace it. If it looks to be simply dirty then you will be able to get by with cleaning it.

Step 2 – Locate it

In order to find your oil pump strainer you will first need to of course know where it is. It will be where the oil line goes into the burner. You will need to unbolt the cover of your pump housing and take the cover off to get to it. From there, there will be a skinny gasket that is around the rim. You will need to be able to recognize the strainer. It is a cup shape that has a wire mesh screen.

Step 3 – Remove Strainer

Take out your strainer and take a good look at it. If it looks like it needs to be replaced then go out and purchase your new strainer if you have not already. It is a good idea to take your old strainer with you to the store so that you will be able to make sure that you have the right one to take home with you.

Step 4 – Insert New Strainer

Get the new strainer set in place where the old one was. It should fit in with no issues. If you are having problems putting it in then you may have the wrong size. Compare your strainer to the old one to make sure that they are in fact the same.

Step 5 – Finish Up

Once your strainer has been set into place you will then need to take the old gasket out and replace it with the new one. It will simply be placed on the rim. Bolt the cover of the pump housing back into place. Once you have done this you are ready to use your furnace.
