I have a 2004 gtp comp g and need to upgrade the pump so I can convert it to e85. Im confused on if it is a venturti pump or not and where and what brand would be the best to get. Thanks for any info!
 


I was looking at that one, but when you type in my car it says not compatible? And still dont know if its a venturi style pump stock?
 
Yours I would think would be a ventri like the 01-03 gps, but you also have a semi returnless system, so I would talk to one of the vendors and check your options.
 
So far I havent found any good info about what type of pump I have? Called a few parts places and got nothing other than they want to sell me a new assembly?
 


ZZ Performance

"97-00 supercharged cars will want the venturi style pump, the 01+ supercharged and 97+ NA fuel canisters will not need the Venturi style pump."

People have compaired ZZPs pump to Ebay pumps like I listed above and they came in basically the same box but ZZP doesn't off the lifetime warranty.

You could get a non modded Walbro pump or contact that company I linked above. They have both venturi and non venturi pumps.

IIRC Racetronix takes Walbro pumps and modifies them to have a venturi and opens them up a little.<--That is the pump PRJ sells.





 
I think i am going to get the venturi style pump just to be safe, and to not go through all the work of pulling the pump to check. If its not I think I should be able to plug the venturi port and it will work fine. Thanks for all the info! :th_thumbsup-wink:
 
You have a non venturi pump in your car. I don't know if you can just not plug the venturi in and make it work on a venturi pump.
