1979 F150 351M 4x4 California truck I am confident the current tank is EEC compliant, however I dont believe anything in regards to the EEC system is currently hooked up.
My question is... The truck is in FL if I change fuel tanks to a non EEC compliant tank do I just need to add a vented fuel cap and all is right with the world?
I need to drop the tank since I'm not getting a good stream of fuel to the filter when idling. Thinking I picked up some junk when I ran it low last week.
Ahhh thanks ND, was using the terminology from the LMC site. I haven't found the canister or lines anywhere so they must have been removed.
Fl doesn't perform any inspections on any vehicle. Think this ended around 1996 for all vehicles.
In FL you can even legally ride a motorcycle w/o a helmet.
Apparently, the emissions requirement for dents varied by model. I have a '76 F-100 that has the carbon canister and a '76 F-150 that does not. The F-150 doesn'y have a hole on top to accommodate the emissions plumbing but the F-100 does.
Although your state may require that you maintain and evaporative emissions gear that came with your ride, they cannot require that you retrofit this stuff. That would be an ex post facto law which is un-constitutional.

Probably the truck was equipped with the Evap/Em system originally and probably it was removed by a previous owner. If you change to a standard tank, provide a vented cap, and never have to do a State or local inspection, you likely will be "right with the world" (not counting a bit more fumes in the atmosphere). You may have to change the tank's fuel pickup filter and/or any in-line or fuel pump filters also. On my last job I got the tank filters from NPD. They worked well.
One other thing to be aware of (besides switching to a vented cap), the vent hose nipple that's next to the filler nipple is a 180° away from the original location.
Here are some pictures of EEC and Non-EEC filler neck setups that might help you out. Taken from the 1976 Ford truck shop book. EEC is indeed the correct abbreviation as seen below.

Shop manual pics are not gospel, especially when it comes to Ford abbreviations.
Pic from from '73/79 Ford car parts catalog that also includes Bronco's. What does it say?
E.E.C. = electronic engine control system // ev/em = evaporative emission.
If I posted the 1973/79 truck catalog pic, it would have no abbreviation for EEC because the only vehicles that came with it were 1979 LTD/Grand Marquis 351W sold new in CA
