Sorry I couldn't help. I seldom look in this forum anymore. Good news is I would have not thought it was your fuel pump, so good thing I didn't help. ;)
FWIW,
DW and I would go for 6 months cross country in our '96 GBM Cruise Master. It was a nice rig and I took very good care of it. It got to a point where I no longer trusted we could go anywhere in it because of the age, and what time does to things.
A RV'er friend told me maybe I should sell it to someone who would use it locally and love it for that purpose. That's exactly what happened, they are having a blast with it, never going more then a days drive from their home.
It was a good idea, and the stress of going cross country with a 20 year old rig is no longer there. MH don't go cross country forever regardless what some would like to think on this forum.
Glad to hear you're up and running again. Take care.
