Fuel Bowl Pump Diaphragm (proper installation)
Before replacing the pump diaphragm cover, check for warpage by laying the cover on a sheet of emery paper which should be on a smooth surface. Remove the sealing bead, if any is present.
Place the diaphragm assembly on the cover, holding the pump lever arm against the diaphragm so that the diaphragm is flat. Don’t forget to install the spring into the bowl first. Install the cover and diaphragm on the fuel bowl and insert the screws finger tight. Release the lever, making certain the diaphragm is loose enough to flex without wrinkling at the edges, also the diaphragm must be able to be raised so that the flange of the steel diaphragm washer touches the inner surface of the cover. These two checks will assure maximum diaphragm travel. Tighten the four screws in two stages, 1/2 torque the first time and full torque on the final stage (5-8 lb. torque).

Six months ago our statistics showed that only 1% of our web site users were using mobile devices to view the site. This includes devices like smart phones and ipads. At the time I decided it wasn’t enough to get excited about, but recently we noticed that number had gone up to 20%. That is a huge jump in 6 months and then a customer called me letting me know he was having problems finishing an order on his smart phone. He didn’t use a computer, but could get things done on a smart phone. That is just the opposite of how I thought things would go.
This was an eye opener for me and without hesitation, I got my development staff started on changing the site and we recently launched a new site that is responsive to mobile devices. This means the screen adjusts to whatever device is being used. A smart phone will see it one way and a desk top computer will see it another way. The old version was non responsive and displayed the screen one way, no matter what device was being used and wasn’t all that useable on a phone.
So, let the mobile devices come. We are ready.
Do you use your mobile device to use the internet? I would like to hear from you about how you use it.
