I've seen that black inline hose on a 3.8 v6, but it was a Grand Prix GTP.

Maybe the seller sent you the wrong pump?

well i instaled it and it cranks up but shuts right back off.
i figured its just a breather hose but the stock pump already has a breather hose right? one of the big black tubes.

i was looking closely at the stock pump and it kinda looks like it has a spot where u could put a small black hose there but its "plastic welded" shut.


the listing actually said for 99-02..i'm using it on a 98.. but the 98 3.8 is the same as a 99 3.8 right?

it says "in line hose"...so that confuses me.

but it cranks up the car.. put it sputters and shuts off. i did have a problem with the coil packs. do they sell coil pack testers? i can try to test them at ngiht time and see which ones spark...IF the car will stay on long enough.


heres the instructions it came with:
http://www.globalautomotiveofmiami.c...ds/TEC1620.pdf

i read something on one of those "ripoffreports.com" sites.. where they send the guy the wrong pump..cuz it has 3 holes n was suppose to only have 2. and the guy sent the pump back for exchange and they kept the pump and his money.

wonder if i can just block off that "black inline" hose? seems to me like its a breather? but wouldnt a breather say "out line hose". should it face downwards towards the tank or upwards as a breather?

IIRC the 98' 3.8 is all by itself . 97' down & 99'-02' are differentI have a 98' with 3800 and tried to replace just the pump . It ran , but poorly . I bought the Delphi factory replacement unit problem solved .

the 2 cars im trying to put them on are
97 3.8
and 98 3.8
both of those 2 97/98 had the same exact pump with no inline hose.
even my 93 z28 fits up the same way.

what do i do with the black inline hose and whats the purpose of it?
can i block it off.

could just be my coil packs... only way i know of testing them is in the dark. see which ones are sparking. car runs but sputters. has half a tank of gas. gonna clear the codes and read the codes.

A venturi is a small hole..from the sound of it that little black line sucks in Gas from the Bucket and sends it in the Lines.

hhmm. still confused.
isnt nothing to hook the other end of the black inline hose to.
its not just a breather that sticks up towards the top of the tank?

I think it's supposed to suck from inside the Gas tank..don't take my word for it, I'm just going off of looks.

i originally had it pointing up as a breather.
i pointed it down and it ruined the pump. so theres one replacement.

this is a shop installing it by the way.

the instructions say nothing about the black inline hose.

i already mailed the warranty back..so it'll be under warranty.

You purchased the wrong fuel pump. Steel tanks use a universal style walbro as they suck from the bottom of the bucket. 93-98 Fbodies use a steel tank. The plastic tanks (99+) use the style of fuel pump you purchased. The venturi system feeds the pump through a provision built into the bucket. Buy a universal style pump and it will work fine.

Yes, 99-02's use a plastic fuel tank with a venturi fuel bucket. The tiny black tube goes to a small pickup in the fuel bucket.

the ebay company emailed me and said its a breather hose and points down. i guess outside of the sending unit. i'm gonna mess with it today.

update..
from what i understand. this pump is for the later models.. a 98v6 and earlier is different.

i held the pump up out of the tank while someone started the car and gas comes out of the the regular see-thru hose and out of the small black hose.. so i guess its not a breather hose.

i'd hate to waste 50 on another pump if i can make this one work. its hooked up right now but the car will just start and shut off after 2 seconds.

heres the instructions



Ok, here is our install guide that is posted on our ebay store home page.



This will show you exactly where these hoses go.

As previously stated, our fuel pump kit will ONLY fit the OEM Delphi assembly. It will not fit any aftermarket assemblies.
