Matt Cramer has a page on it here also:

Here's another page that shows some other installations, including the fuel filter with the tube installed like I did:

You can see they used a tee setup like I did for the vent/return. That does not work so well, and installing the vent is a necessity.

Get that Monkay! Get that nasty thing!!

Ok guys here is something to think about GM used 3/8 presser fuel lines and 5/16 return lines. Fords have 5/16 or 3/8 presser fuel lines and ¼ or 5/16 return lines. Mopars have 5/16 presser lines and ¼ return lines… even on V10's so I say your 5/16 and ¼ lines are fine. Mopar still uses 5/16 fuel lines. GM does to now days and Ford.

Question: how is this setup ventilated? I'm not sure how air gets out of the tank (upon refueling), nor back into the tank (as the tank runs down). I just see the vent line back to the tank running into the surge tank.

Most of the older slants had vented caps or vented filler tubes. If you want to seal up the tank, which started happening around 1970, you must have a vent of some kind. That normally involves a charcoal canister to trap the vapors until the purge opens them to a running intake somehow.

I was thinking gunpilot had a later model (post charcoal canister) slant, but maybe not... A vented cap would certainly fit the bill.

Charcoal canisters came into use around 1970, (maybe earlier in California) and have stayed. It is the older cars that do not have them. They had vented caps, and could experience fuel spill under hard cornering.

I was also under the impression that Gunpilots Duster is later, which would cause it to have a sealed tank, and a charcoal canister for vapor collection. I have not seen a photo of his car in awhile though, so maybe my memory is wrong.
