Thread: Installing non venturi pump in a venturi canister?

Hey guys I have a 99 gt so i assumed my pump was non venturi so I got an aem e85 non venturi pump. I pulled the pump tonight and it was a Delphi replacement with venturi. So I've seen threads where people have installed a non v pump in a v canister but most people say drill a hole or multiple in the canister. The question is where do I drill and what size holes? This is strictly a temporary thing as soon as I'm able I'll be getting a non venturi canister but since I already have things taken apart id like to get it installed. Thanks for the help everyone.

Perfect thanks a lot man!

3/8 seems kind of big lol

Well I got it installed with the holes drilled like boosted Pontiac said and so far it seems to be running great although I do have half a tank so I'll have to see how low I can go before it starts giving me problems. Thanks man!

Ya I think I'm just going to go fill up a couple gallon gas tank and drive it till it starts displaying negative symptoms so I know where my limit is at. Hopefully I'll have a regular non venturi pump in a week or two though. 😀
