OK, 1st post here.....and I have searched this board and EVERY other but cannot find an answer to what should be an easy question.

Just got my injectors, pcm and walbro (in-line) from Allen yesterday. I was gonna start doing the fuel pump install tonight since I figure easy stuff...just cut the line and insert pump. Within 10 secs under the truck I noticed metal fuel lines. Hmmmm I'm installing a whipple but I found info on installing the in-line pump from the Radix instructions (man that kit is soooooo complete)....anyway....in that kit is a 10mm male to (I'm guessing 3/8" female NPT). The way the Radix manual suggests is to :

1. Disconnect the fuel filter line going towards the engine
2. Connect that line to the Walbro via Radix supplied adapter fitting
3. Install Barb hose fittings on the receiving side of Walbro
4. Install a modded tube fitting and barb hose end on the vacant side of the fuel filter
5. Connect 3/8" fuel hose on both fittings, bolt up pump, connect power and ground, done......

That's sounds simple....only problem...where can I get these adapter fittings???? And I don't really want to chop up my fuel line when there's a better solution. And I'm just guessing that the original fuel filter fitting is 3/8" NPT.
