1998 GMC Safari I have 2 noises I was hoping you could give

1st noise just started about a week ago It is a high pitched noise when the van is running. I have crawled around the van while it was running and it seems to be coming from the gas tank area. About a year ago I hade a new delco fuel pump installed. Is this a sign of bad things to come?

2nd- Every so often I have a popping noise in my right front. My steering is good no shkes or wobbles. Tires seem to wearing well I am just concerned.

Thanks for you help
