hi all,

looking to purchase some EFI conversion stuff for our G20, have settled on Holley Sniper + Hyperspark ignition system.

Beyond the Master EFi kit and Hyperspark, should I be looking at any other bits n bobs, say fuel pump, return line etc?

any suggestions much appreciated!

I wish I had some info to help you with.
I've got a buddy that put a Holley Sniper setup on a V8 converted Humvee (He's loving it), but I don't know anyone running one on one of our vans.

He did have to figure out a return line and use an electric fuel pump, but that's all I know that would cross over.
He also had various issues with throttle linkages and stuff, but I don't think that was so much because of the Sniper and the 454 as much as it was a Humvee engine compartment/clearance issue.

Once he got it all sorted though, it was amazing.

cheers,
turns out the master kit already contains everything to do with pump and lines so just went ahead and ordered that + the hyperspark stuff.

Will update here with more info once it's up and running smile
