Thanks.

Since I installed the GFS-392 (see link in sig) kit I've been @ 20# idle and no lower than 17 @ WOT, comp on 5-5:-laf. After the draw straw install I didn't see any change in pressure, but knowing the straw is 1/2" versus the stock 1/4" (or whatever

) gives me a satisfied feeling that the fuel supply "volume" is enough to keep the GFS pump and the VP happy. I had to uinstall the draw straw because I cracked the old rusty stock line to the module, it was either the $50 draw straw kit or god knows how much for a stock replacement module unit (I've heard they're about $3-4 hundered from the dealer).
As far as capacity/usefull fuel in tank - I just fueled up from "bone" empty today (finally used 1st tank full since install) and I ran it down to under "E" :--). Not sure how many gallons it took as I fuel up from my (eh) own (pinky stuff) fuel tank. However, I usually only get about 385+/- miles per tank (mainly stop go - I mean stop & "Punch" it:-laf driving) and the trip OD read 420 after I filled it. So I ran it pretty low. When you do the install determining the length to cut the straw to is kind of tricky (long explanation / instruction following, but definitly worth the minute read time).
After the module was prepped to receive the new straw, before I "final" cut it for length, I flat cut the bottom of the straw with a PVC tube cutter tool, then installed it into the bottom of the modulre so the billet piece was sticking out the top of the module, roughly 1-1/2 - 2". I then installed the module, new module to tank gasket (for ten bucks don't bother trying to use the old one) in place, tighten the ring by hand, then measured the difference from the top of the module to the bottom of the billet piece and final cut the straw, a "red heads _ hair" longer, at a very slight degree angle. If I could design the straw any different that it is I'd make it so it had a "loop" that fits inside the module, like the stock tube - this way there's a bit of movement if necessary. May not make sense until you look at the spare parts picture at the end of the link. But, so far "it's all good".
