I'm playing it safe and just installing the same type. I remember a few
years ago Marty at KRC telling me how to make a return style system using 2
fuel rails, cut them in half using the halves with the ports. I think he
mentioned from a Ram. Obviously more details I can't remember.
Since I need to replace the fuel lines I may throw in an external filter as
you pointed out. Just use the same type as in the return style systems.
According to the FSM (yea, I should read that more before posting
questions), the systems without a return line use the supply line to return
fuel through the regulator.
Rock Auto...way cool. $50-$65 cheaper than any local auto store. $196.00.
I know people are sometimes looking for discount codes. Just Google "rock
auto code" and there will usually be other forums posting current codes.
Thanks,
James

One nice thing is that with the older systems, you got a fuel filter
instead of just depending on the internal sock. Another is that with the
external regulator, you could tweak the fuel pressure if needed, and a third
is that they were nice for running a dry nitrous system since the fuel
regulator could be bypassed to provide additional fuel by the nitrous
system.
But overall, for normal use, I don't think there is really a huge
advantage one way or the other. The returnless system has the advantage of
half the lines to rust out, less parts to break, etc.
Probably the easiest thing to do would be to replace it with the same system
you've got, unless the price difference is so huge that it makes economic
sense to go in a different direction. Then again, since you plan to go to a
408 in the future, it might be worthwhile to get the ability to easily tweak
your fuel pressure. (I'm not certain how the fuel pressure is adjusted with
the returnless system, but I'm guessing there is a regulator of some type
built into the pump itself, and the "fuel return" line never actually leaves
the tank.)
: Would a return style pump function if the return port was just capped off
: for now?
I think it would probably build up too much pressure in the fuel rail.
If you did go with a return style pump, I'm guessing you would also need to
install a fuel pressure regulator (even if you just put the regulator right
there by the pump, under the bed).
