So epoxy is good for oil pans, not for gas tanks?

The oil drain fittings were welded to the oil pan, smart ass.

Anyone ever use one of these before to vent a gas tank? I've had pressure/boil over issues for years with a full tank and direct sunlight; and just so happen to have one from my old Camaro. Evidently it is a two way fresh air/pressure vent valve.

I've opened up the old return line to act as a secondary vent and enlarged the factory purge line to improve the total volume/flow out of the tank. I hope this solves the issues I have been having, or at least keeps the car from dumping gas on the ground.

I am doing some other minor mods to my double-pumper hanger... I'll post pics tomorrow.

Not back there but yes.

Took a few hours tonight to monkey around with some things.

The first thing I did was braze together a section of 1/4", 5/16" and 3/8" steel line; I've since painted it to prevent rust. This gives me a way of connecting the stock vent line, return line (now vented) to the F-body tank vent. I'll be placing the vent up by the filler neck when it comes time to reinstall the gas tank.

I pulled the downpipe tonight after MUCH struggling just to find the wastegate puck bent, as in not even close to sealing. I've managed to bang it back into sorts. If I find that the puck has been out of sorts for the last 10 years and contributing to my slow-spool issue I am going to have a litter of kittens.

Lastly you can see the mods to the hanger to (hopefully) aid in venting.

Just ordered up some submersible 3/8" rubber fuel line from Gates  (P/N 27097) - $35 for a foot! Help me, Jebus!

Beats having a blow-out; and it is better than the swollen line I found in the tank when I pulled the hanger - yikes!

SAE 30R10, not cheap
~$20 from Jegs?

[SuperSix]

Meh.. $35.00 for peace of mind. Small price to pay.

Got it for $26 out the door... it helps to go into a store in uniform.
 
For the sake of comparison I paid $2.50/ft for regular FI rubber line -

The gas tank is back in with the new vent run; both pumps turn on so this is good news. I still have to pressure test the system to ensure that my work is good. I now know this was a good idea because the old rubber lines were badly dry rotted and cracked when I pulled them out.

Suspension is now greased, and differential is refilled with GM 80w-90 (plus a some Irving HDH gear oil I had laying around: http://www.coastalbp.com/uploads/file/pdfs/Irving/Infotech_en/5.%20Manual%20Transmission-%20Industrial%20Gear%20Oils%20%285%29/HDH%2024may2010.pdf) and a bottle of GM limited slip juice.

I also spent countless hours yesterday (and fingerprints) planing the header, turbine housing inlet and outlet flanges with a sharpening stone to true them up. They still aren't perfect so I may end up running this gasket (Vibrant P/N 1461): http://vibrantperformance.com/catalog/product_info.php?cPath=1022_1068_1127&products_id=134 It seems to line up perfectly.

After breaking my impact gun - yay for Chinese tools, and subsequently fixing it with parts from an old IR gun that it was a knock off of, I got both the front wheels off to find flat spots on both tires. Which explains the horrible vibration the car developed last August... and here I just thought it was the warped axle. LOL.

I remember flat spots-or I think that is one of my memories

Well this sucks a little. The main fuel pump won't prime now, it did yesterday... however if you put power directly to the pump it runs. Fuse? Relay? Oprah? I am recharging the battery to ensure it isn't the culprit, even if I can switch on pump #2 and it runs fine.

Or just don't hit your fuel pump kill switch - which you forgot you installed. Yeah I need fewer cars.

Just ordered up a pair of Nitto NT05 255/40/17s for the front... $390 shipped to the door with the tariffs pre-paid, which means no surprises - thanks DiscountTireDi rect.com!
