Bubbling gas & expanding gas tank

How about this stuff?? A lot cheaper than the product at a racing site abd appears to be made of a similar material as the "Ove Glove"...which we have here and it does work for things hot out of the oven.

Plus now there adding ethanol to gas, not sure what effect that might have if any. Hmmm a bubbling plastic gas tank setting right behind the seat. That would make me very uncomfortable too. I have not had the dreaded Vapor lock as of yet. I did notice bubbling in my gas line when I first got it, so I re-routed the hose away from the engine compartment, and it seems to have stopped. I’ll have to keep an eye out on the tank. /forums/images/graemlins/ooo.gif

Farmall,

Here's a link to a follow-up post on my solution to the fuel line insulation {HERE}

When was the last time that you changed the in-line fuel filter?? If it has been a season or more, I would empirically change out the filter first. NAPA, Advance Auto, etc all carry 'em. I use a 5/16" nipple metal canister filter (Deutsch #FF203), and I replace it at the beginning of each season.

Farmall,
I hope you haven't went out and spent any money on anything yet. If your tank was expanded and you had a gush of vapors release when opening your cap this is definitely a cap/vent issue. Could just be you have some crud blocking the vent hole(s). Take off you cap and you'll find a small hole (maybe more than one) in the inside lip of the cap. Find a small drill bit that will fit the hole and run it through by hand to make sure it's clear. I think Terry told me that PT vented these caps themselves. May want to call him and check.

I think the bubbling was a side effect of the gas being heated under so much pressure. Fix the venting issue first and then keep a watch on your vapor/bubbling issues. Since you've had no problems in the past I'd bet that it goes away with corrected ventilation.

I actually did hear some hissing before removing the cap so maybe it's working OK?? But I will check it anyways. I have not yet replaced the in line filter /forums/images/graemlins/blush.gif but I will do so this week-end. Visually it looks OK but it will be replaced anyways, esp since they are so readily available. Thanks!
