take ur time

Verry nice write up.

dude, you're my hero! , some people mention noise with the Walbro 255 pump, have you noticed anything?

So it comes out from the trunk... NICE

Very cool!

Anyone know if the Series I has the same fuel pump set-up as Series II?

It is the same setup on my 96

Kudos dude for maklng the weite up. I tried when I did mine but I botched up my sending unit and ended up not taking pictures.

i tried to stay calm when i was doing, i had to stop many time to calm down cuz my POed level was getting up there. but in the end i got it done. not bad for my first time

BTW as a heads up to any one want to do this the BLACK WIRE GOES TO THE BLACK WIRE, RED WIRE GOES TO THE GRAY WIRE

Great writeup. Im going to attempt this next weekend and am a little nervous. Any idea if this kit here :
http://intense-racing.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=IR&Product_Code=3800-FTS-VFP&Category_Code=3800_Fuel
eliminates the need to mod anything or will I still be cutting the venturi on the walbro.
Also, with the fueling issues Ive been having I was thinking of purchasing this:

I dont have alot of mods and dont really plan to do alot more, maybe a cam or lifters (maybe). Think the 42lb injectors is overkill?
TIA
