HEHE - should I show him my earls list?

Stock lines aren't threaded - you need -6 weld on fittings. You can use -8 if you want to upgrade to a larger pump later.. which would be a good idea anyway.

The stock line is 3/8" I believe - therefore you need 3/8" hose or -6.

The car is 14ft from nose to tail - you figure you need about 10 feet to get from the firewall to the pump.

You're going to need a feed and return (if you choose not to use the stock hard lines you'll need)

(4) -6 or -8 Weld on fittings
(4) -6 ot -8 ends to attach to braided hose (angle is going to depend on your setup)

If you leave the stock rails in tact you can use a 120 degree for the secondary outlet, and then you'll need (2) -6 straights (or -8, whichever once again) - one for the secondary inlet (feed) and one for the primary outlet (return). Since you won't be able to use your stock regulator you need a fuel pressure regulator... then you'll need -10 to -6 or -8 reducers for that, plus required fittings.

Then if you decide to go throught he bay door, you're going to need bulkhead fittings, and 90 degree fittings for the feed and return at the pump, also you'll need to insert inline filters which are usually -8 - which are recommended - so you might as well do everythign -8.

I can go on and on about this forever. If you want some questions answered, I can help.

Either post here and I can help make you a complete list of what you'll need, or I can just give you an idea.
