mountaingoatgruff Posted February 7, 2008 Share Posted February 7, 2008 i guess this may be another dumb question , but i can't find this thing in my haynes (maybe i just can't find it cuz i don't know what to look for to begin with but the cars in the pics in my edition don't have this part). anyhow, i'm sure plenty of you guys know... what the hell is this thing? its hanging off the back of my driver's shock tower and it looks to be part of my old emissions system. it doesn't seem to serve it's purpose all by itself so please tell me i can scrap this thing since i'm going spfi - i kinda need somewhere to stick that freakin coffee can of a fuel filter. also, this next pic kinda sums up how far along my spfi conversion is. see all the missing parts and loose wires? i put my coil below the battery. this way i can still buy plug wires made for my car and they'll fit the same. the relays are hanging in the wind by the passenger hood hinge for now. i got a piece of 11gauge steel plate to make a base and i'll use an outdoor electrical outlet cover over top of it to enclose the fuel/ign relays and fusible link in there with some leftover space for future expansion (lighting relays or whatever). i also decided to make a new hold down plate out of the leftover 11gauge for the dist instead of opening up the bolt slot. i thought it'd look better is all. should be up and running by the time man develops colonies on the moon!

subyrally Posted February 7, 2008 Share Posted February 7, 2008 if that is what i think it is, its the anti backfire valve, or something along those lines. think it keeps the engine for backfiring under deceleration. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 8, 2008 Share Posted February 8, 2008 That is the anti-afterburn valve. It's function was to shut off fuel flow to the idle circuit under closed throttle coasting. Thus preventing the small poping noises of fuel combusting in your muffler. It's entirely useless in your case. GD Link to comment Share on other sites More sharing options...
subyrally Posted February 8, 2008 Share Posted February 8, 2008 That is the anti-afterburn valve. GD thats what i was trying to say, lol. i should have known what it was called since i just unpacked one last night. on that note, dont leave car parts in the shipping boxes in the bed of a brat during winter, that was nasty.

Durania Posted February 8, 2008 Share Posted February 8, 2008 I wondered that for awhile myself, when I took a more in depth look at my Weber setup; I found it to be disconnected and removed it and made for a good tarp weight for the parts Brat.

Or all the cracks and holes in my are causing all the popping. Wonder if it will hurt my DEQ.... Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 8, 2008 Share Posted February 8, 2008 Most of them have failed by now. There's a check ball that's held in by a pin - the pins rust through. And the diaphraghms in them are 20 years old as well. GD Link to comment Share on other sites More sharing options...
