Hi. Thanks for using JA! I will try and help you out.

There is a special procedure to replace the transfer pump on a C7. Do not just remove it.

However, if your losing fuel prime, the most likely cause is a faulty regulator valve on the back of the head. I have replaced hundreds of these over the years for this problem.

Let me know if you need more help or have more questions.

we replaced the check valve on the back of the head as you sugested, but while cranking the engine to start it we managed to burn up the starter. as soon as i get a replacement i will try to start it again and i will give you the results. John
