Unhappy Please Help!!!

Please Help!!!

I am about to change the fuel pump on my 96 C280 and I need some quick pointers!!!! PPPLLLLEEAAAASSSEEEEE.....

First do I clamp the hoses going to fuel pump? do I need to change the hoses too even if they are in good shape?

Do I need to do anything else?

I disconnected the battery in order to work on the car safely. When I put the terminals back do I need to do anything else, like purging fuel or similar?

Your help will be greatly appreciated.

In advance thank you.

fuel pump

rp96 For safety, do you have a ramp or the proper equipment to raise and secure your car safely while working under the car, and remember latex gloves and safety goggles?
I've not done your model, but it is pretty basic to change fuel pumps. Do disconnect the battery negative cable and secure the cable away from the terminal. Unplug the electrical wiring on the fuel pump (good idea to mark/label all the lines). Be careful of how you clamp the fuel lines as not to damage them, and then disconnect them. There will be a certain amount of leakage, so have a container and rags under the pump to catch the fuel. Some lines are connected with bolts and have washers on the bolts, these washers are not to be reused. You should have, if needed in your application, new washers when you reconnect, these are known as banjo connections. Notice how the pump is bolted in place and disconnect the pump. Then just reverse the procedure to install your new pump. After the pump and lines are connected, start your car (will take longer, due to air) then check for leaks.

enjoy your drive, timreid

Dear Tim:

Thank you very much for your advice, highly appreciated.

Yes I do have ramps, latex gloves and protection glasses.

I am glad that is that simple (hopefully)

If there is anything that I can be of help or your ever visit the Miami area don't hesitate to let me know.

Best regards,

R Pertierra
