I hate being a newby sometimes.... these are expensive mistakes!!! I thought I did a pretty good job too. I used all A/N, All SS hose, used a painless wiring/relay kit, etc... only to have a quart of fuel PUKE down into the pan as my end result. I could open a "AN fitting store" at this point...
Wabbit: I have a new Mallory fuel filter very close to the tank. I managed to do it all gravity fed to the pump. I installed one filter is all. I thought about a second, (I do have a 8AN inline filter @ home), but I thought it would be too excessive. It is a return line system too. I hope it all woks out (I still have not driven the car w/ the new fuel system.
The other thing I noticed is that the insulator pad for the pump is not enough to keep it as quiet in my opinion. It cannot be heard when the car fires up though.
