Default "New" 255plr Walbro Fuel Pump - Popping fuses??

Fellas,

I picked up a "new" walbro fuel pump from a fellow TR member because my other pump was showing indications of taking a dump on me.

I installed it last night, mind you I had a walbro in the tank already, so i didnt need to wire anything up...just plug it in and go.

First start: the KA turned over and over and nothing...so i pulled the pump and checked the make sure it worked (jumped it direct to the battery - and it wrrr'd away so that wasnt it...). Then went to the fuse box and poof!! - the 15amp fuse was blown. Reassembled everything, replaced the fuse and poof again. WTF right - its 12midnight i'm doing this, so I'm quite annoyed @ this point.

Just for Giggles I toss a 20amp fuse in the slot and it takes right off...fires up and runs perfect. Take a test drive, go over a speed bump and pop...the 20 amp goes pop!!

I'm thinking that i might have disturbed the wiring enought to make this happen...especially since the "speed bump" issue. I've driven 30 miles or so since with out an issue...but i'm still running a 20amp fuse...I know "not good". :\

Is there anything else you could think that might be causing this issue, other than crap wiring? Bad pump?

Thanks ,
-Royce

Also - I plan on installing an inline Fuel Pressure Gauge after my FPR so i can confirm decent fuel pressure...what, where and how would you guys recommend i do so? (yes, i've googled - just looking for additional feed back from you guys, maybe someone that has done the same.)
