Ok I guess these are better than regular dykes (that's what I normally use, and I'm pretty sloppy and could just cut the ends closer)? I will definitely consider it but I should probably go back and cut these closer with some dykes to begin with.

 

Hmm that's an interesting point and something else to think about... I will definitely look at how close the exhaust is and if it's a problem. Not something I thought about at all or considered but would make sense if it's cooking the tank that it excessively raises the pressure and causes more fumes..?

 

Ya I'm pretty sure I'm running the DW200 sock. I posed the questions on facepage and seems like it's hit or miss with some people regarding fuel starvation. A couple people said the switch to a walbro solved the problem, whereas someone else said running a Holley Hydramat was the real fix. Did any tracks have a long sweeping left hander you visit Zak? I think I recall you have a long right handed sweeper. I haven't touched anything close to the pump hangar so I should probably inspect those. Based on the gas smell in my garage I think the vent is "working," the issue is just how to make it less strong the odor. I will check it though thanks.

 

IIRC, the DW200 fuel sock may be the same shape as the OEM one? Would have to look at a picture again to check. I remember running whatever sock came with my pump and it looked the same as what came out of the car.

We do have one track that has a super long (9-10 seconds) sweeping left regardless of being run CW or CCW. I'm actually fuel starving there at under 3/4 tank in my current car ever since going e85/turbo. The NA never had an issue, though. I should look into a Hydramat a bit more...

Wish I could help more with the odor concern. I've got the same general evap setup as you (tank venting straight to atmosphere and no canister/canisters), and haven't experienced the same thing in my small garage. I'd think it's gotta be the exhaust heating up the tank and causing pressure buildup like Six said...

 

I will literally Venmo you $3 to go buy some .

Peace and harmony

 

Even if there's space between them, if there line of sight then the radiant heat will cook the tank. And the diff, and the trans.

 

Ha ok you made your point! I will DM you my venmo now. I guess sometimes the extra sticking out provides me some mental reassurance in case I need to adjust it tighter in the future I can grab it with some pliers and tighten it? I'm grasping at straws, I know..

Oh for sure. I will have to take a peek under there and see how much surface area is close to the tank and what the possible solution is. The easiest solution is just header wrapping the sections that pass close to the tank. A nicer solution would be making some heatshielding material out of the embossed Al, but I'll have to see where I could go about attaching it to the chassis.

 

I'm just giving you a hard time... but they are worth it.

 

I have a small pair of side cutters I use for that purpose, and I grappled with your dilemma too. At first I would cut them long, telling myself I will come back to trim when I am certain I don't need to tighten them - but I never tightened them, and never came back and trimmed them either. So now I just pull them tight, trim them, telling myself it's only a zip tie FFS, cheapest item on the car by a country mile.- and I don't think I have ever had to replace one because it was not tight enough.
