Fuel pump install... not so straight forward?

[camarokidz28]

1999 GTP
Well my brother gave me a fuel pump for Christmas. I figured I would install this thing today... Not having given any research before hand figured it would be pretty straight forward process... I was wrong

Can someone please help me out here cuz i'm lost. I'm thinking I have the wrong pump maybe? or someone swapped out the pump with a different year? I looked at http://www.intense-racing.com/walbroinstall.shtml and my canister is different from that one. additionally the pump I pulled out does not have any brass fitting on it
The new pump is a TREperformance tre-344 which is for 97-00 grand prix

Pull the hose off of the old fuel pump. you'll be able to tell that they're pretty much the same.

I think you can cap the Venturi port and run it without, other than that it is pretty straight forward, reuse the old fuel tube put it right in there like the old one was

Edit- never mind I see you have a new tube, put the new one in just like the old one ask James if you can cap that port

Yeah looks like someone tossed in a non venturi cannister....though since it was around 2000 that they no longer used venturi cannister s on gtps iirc you may be late enough of production to not have one...
That pump is venturi....you'll have to block off that brass pressure bleed to the venturi hose....

 

[camarokidz28]

So I put on the new filter and cram it in the plastic canister? or re-use the old filter that wraps up the side?

If I use the new pump I can't go below 1/4 tank of gas?

If I had an old style housing would I be able to go below 1/4? I do have a parts gtp in my back yard

Edit: I googled the PN# on top Delphi FG0151-01 came up with two parts under the same number. 1 with filter on bottom 1 without.

with filter (mine) http://www.autopartswarehouse.com/s...FG0151fupude&gclid=CIrRleu_tr0CFUNo7AodqBUAMQ

without filter - http://www.summitracing.com/parts/dfp-fg0151?seid=srese1&gclid=CJey3I-_tr0CFWZo7Aod2TEAXQ


OR..... Would I be better off just leaving it alone? I don't ever plan to switch injectors. and the car starts first time every time, so I don't believe my old fuel system has any faults. I was only swapping it because I had the parts here. I don't want to render my car undrivable with little mods that I don't necessarily need. And to me not being able to go below a 1/4 tank is undrivable. I don't want to limit my car to 200 mile fuel range

If it aint broke don't fix it. If the car runs fine then leave it alone and save it for when the stock pump craps out.

I just replaced mine in my GTP. Was not so easy also..

Do you have to update the harness

 

[Xtant12]

P.S.


My garage floor is same color!!

 

[1quick]

If you don't need to change it I would keep the stock one in there

Is you're peeling off too?
$350 well wasted

supposed to be a direct replacement I thought. except it looks nothing direct about it. the harness it looks like you just have to pop off 2 pins and put them in the new plug

 

[Xtant12]

AHH, I changed out the fuel module and the direct replacment comes with the GM re-design ( updated ) harness that you have to wire in. My issues were how to split the harness to the car and the ZZP rewire kit.


No my garage has held up. I got the 2 car garage kit at lows for 75.00. painted it on myself. 2 years running not a single spot has came off!!

So did you buy a stock pump, or a 255 pump?

 

[camarokidz28]

I didn't buy it my brother did. The box says 255. and it also says oem replacement

 

[b4black]

What is the function/purpose of the venturi?

 

[Alacran]

You need the stock fuel pump canister. The canister in the pictures is after market.

Hmmm. If its a 255 pump you should run a rewire with it.

I have a zzp rewire kit, he gave me with it. but.... I don't like the idea of hacking up a rigging in a wire. I'd rather just run it with the stock wires

That's what I thought, i'll pull the canister out of my parts car and see what it looks like
Edit: the parts car is the same style pump as this one, looks like someone JUST replaced it.. so that kinda sucks

I got a brand new canister on ebay with a brand new fuel pump and filters for 45.00 shipped. Only down fall was it was the new GM design and I had to wire it in and figure out how to get it in with the zzp rewire.

Looks like ebay or finding someone online is the best way to get a stock canister around here.

Anyone got one laying around they wanna sell?

 

[Larz01]

Any benefit of cutting a slot on the bottom, rear of the fuel pump assembly in hanging the fuel pump filter sock out of the canister for non-venturi pumps? Or, am I just hearing things. ( currently, running out of fuel on top of 2nd gear, going to replace my 4 year old 255 with a new one hoping for the best).

 

[1quick]

You can drill a couple 1/2 inch holes in the canister to help it fill faster, the more holes you have the more slosh starts to become an issue with low fuel levels

i finally found a fuel pump canister from the junk yard. initially i thought the car was a 97 but the emission decal said 98 model year and boom completely stock fuel pump canister with every i need...unfortunately it is only one and it will be my back up.
