Hello All: Not sure if this question has been addresses here as I couldn't find it, But,,,, I'm doing a V8 conversion in my 914 with a late model GM L83 aluminum block that has direct injection. I have purchased an in tank pump( Holley Sniper) to supply the direct injection pump on the engine. This is a non return type system, although the pump has ports for Return and a Vent, the return is plugged in this scenario. My question is with this do I need to keep the Yugly Fuel expansion tank?? Also where does the Vent go from the intank pump?

Thanks in advance for any help.....

A returnless system has the after fpr/return built into the pump assy so it just dumps back into the tank. Less heat transfer from the engine this way. Don't block holes.

In newer cars the charcoal canister doubles as the expansion tank. You will need something or the tank pressure releases to atmo and you smell it.
