Thanks Larry, yeah that mat is a PITA, but bulletproof. I'm still not 100% happy with how it is laying near the firewall, but the rest of it has settled down. That's exciting about the Raylar cam. They have some pretty cool vids of some wild 8.1's on their web site.
I've actually been referencing your good write up on CK5 quite a bit as I plan. Do you have a good source for purchasing new workhorse parts with "reasonable" shipping? I'm going to try using the in-tank sending units for the fuel system and the AC Delco EP241 pumps along with a direct replacement switch rated at 65 psi. Check out the data sheet link below. I think the previous version of this part from Pollak was not rated for as much pressure.

It is supposed to plug right in where the stock 87-91 valve goes using the stock switch. The three tank setup is intriguing, though I would need a loan to put 80 gallons in at a time if I added a suburban tank in the rear. $135 was bad enough last week...
