Blazer Tank Swap

[Russell]

Hey guys!

I'm sure a couple of you fellas have done this swap already, so I thought I'd get some advice before I dove into my fuel tank swap.

First off, the placement of the crossmembers -- Is there any science to this, or do put the rear crossmember in, bolt it up, put the fuel tank up with a couple jacks and put the next one on, or is there a different procedure?

Second off, would there be a problem with running a homemade filler hose out of exhaust pipe that'll run along the inside of the frame rail to the stock gas door?

Finally, would it be safe to run rubber fuel lines from the fuel tank to the fuel pump, or should I run with metal compression fittings the whole way?
