Mike D Posted May 9 Share Posted May 9 I’m looking to replicate the fuel system and throttle linkage for a 60s gasser with a Hilborn injector with a 671 Blower amd moon tank. Can’t seem to find any clear pics. Any help is appreciated. Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted May 9 Share Posted May 9 (edited) I answered this a while back but some of the pix have disappeared. Here's a mechanical injection plumbing schematic. Between the two, that should be enough. There is linkage from the throttle pedal that operates the metering valve (sometimes called "barrel valve"), and the throttle butterflies. EDIT: The link below will take you to an explanation of mechanical fuel injection. The linkage and plumbing should start to make sense if you read the material and look at the pix. https://www.enginelabs.com/engine-tech/fuel-cooling/need-know-mechanical-fuel-injection-types/ Edited May 9 by Ace-Garageguy 1 Quote Link to comment Share on other sites More sharing options...
Raoul Ross Posted May 9 Share Posted May 9 I always wondered why there was a second set of nozzles (usually smaller) on Velocity Stack-type FI units. I never thought of them being idle-speed injectors... Thanx Bill! Quote Link to comment Share on other sites More sharing options...

hedotwo Posted May 10 Share Posted May 10 In addition to what Bill posted, these might be of help too? I've had these saved for a long time... back when I used to get into small detailing 😐 1 Quote Link to comment Share on other sites More sharing options...
