Thanks you guys for the kind words.
Lin, Good question - several reasons:
1) I'm not totally sure about my exhaust system yet, but for the last 20 years I've run a side dump in front of the rear tire on my 100-6 and may do that this time & if so, no issue.
2) I've never been totally convinced it's particularly dangerous this way, they made thousands before switching sides. I've never had a leak at or around the fuel pump, although I'm sure it's possible. OTOH, the other side has the main battery cable nested against the fuel line which could get very hot if shorted - which is potentially more dangerous?
3) Although I love 'personalizing' my car, I have always tried to make sure any mods are easily reversible since I am just a 'caretaker', and the future owner may want stock stuff. So I built the mounting plate to bolt to the existing fuel pump weld nuts because this was the easiest way and didn't require new holes in the right side bulkhead. The pumps, filters, check valves and connecting fittings are all attached to the mounting plate on the bench. Then just four Allen bolts to secure the assembly to the bulkhead.
4) The fuel system plumbing is stock routing - except for using a slightly different shape of the line from the tank to reach my connection at the fuel pumps, and shortening and re-flaring the line to the carbs (I used copper/nickel lines so they are easy to re-shape). Otherwise all the stock fuel line mounting clips and such are still used.
5) I have the 100-6 I raced and this early BT7 I'm working on and both have the fuel pump on the left. Never having had one with the fuel line on the right, I'm not too sure of the routing of the fuel line in the engine compartment if run up the right side.
In short, this seemed like the easiest and most easily reversible way to go.
