914 Fuel Expansion Tank?, In Tank Fuel Pump Options

[Conceivedready61]

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.....

I have to ask, why reinvent the wheel?
Is there some performance increase? Some other factor that outweighs the cost, and engineering required to make the system to work safely?

If it’s simply price problem (ie you have a 3 port pump and it’s $900), why not pick a more proven solution that has benefits in other areas.

If this is the case relocation of the fuel pump to the front, under the tank, is less expensive, proven, and helps with vapor lock. There are several threads here on it. I consider it a best of all worlds. When I did my 72 it cost me less than $200 and I replaced all the rubber hoses.

Hope you find this helpful.
