    The wrenching saga continues. One of the failings of the Atom is in very few cases they use substandard parts, like fuel tank gaskets that are actually not fuel safe, LOL. So, I have to remove the fuel inlet flange as well as a fuel pump flange to replace the gaskets with a fuel safe gasket material. I opted for Viton. Fortunately, the gasket material I purchased is the same thickness as the junk that Brammo and TMI use. Hard part is removing the flanges. The fuel inlet flange isn’t too difficult however the inlet pipe is angled to minimize access to a couple of the screws holding the flange to the tank. Removing it is a test of patience and not so much difficulty. However, removing the fuel pump is an absolute test of patience. For whatever reason, Chevrolet elected to manufacture a fuel pump assembly, which given the marginal clearance of the fuel cell to the frame mandates that the fuel cell be unbolted and moved back from the frame and carbon tub. Looking at the assembly, you can see that the deterioration of the original flange caused the return filter to become plugged. When I dumped out the fuel out of the fuel pump assembly, tiny little pieces of the gasket came out with it. So I’m going to check the tank as well to ensure that there are no pieces left inside there and I’m going to fish them out. Now, I have to replace the submersible lines, filters (the AEM E-85 fuel pump I have already has one filter) as well as the pump I’m also replacing all the lines with Aeroquip E-85 safe lines and hard anodized AN fittings to in sure leak free performance over the long run.
    Someone asked on a previous thread about my lift arm extensions. I was asked where the arms actually connect to the frame. I have included a couple pictures in this post to illustrate.

    Here's the pics of the lift contact points; 30728085_10215081762051974_7309105502628867414_n.jpg30724664_10215081762091975_6368946549757400629_n.jpg

    Question: where would I find the return fuel screen that sits at the bottom of the fuel pump assembly?

    unfortunately the pump assembly is only sold as one unit and you could not order fuel socks separately. I bought a few sizes of socks with the walbro pump I used and just jammed the one that fit best in there.

    I see fuel pump assemblies on Car-Part.com--Used Auto Parts Market for as low as $35 to get a used one from a junk yard.

    I deleted the rubber loop on the lower thermostat housing to bypass the heater core circuit. I noticed the hardline is approximately 1/16 of an inch away from the header. You can actually see scorch marks on the hard line. So, I again tasked Matthew Lambrecht of #CaliberCustoms to delete the loop and hardline, weld up both ports and drill a passage from the heater core outlet to the main body of the lower thermostat housing to complete the original circuit. It’s a much more elegant fix. Side benefit is that under hard acceleration, the dash temp sensor won’t see a spike in temperature as a result of being so close to the header. I also don’t have to worry about the failure of that rubber hose. #becauseracecar

    That's a nice fix. Mine had a different heat protector on it and I added an extra layer for good cause.

    Have you considered a remote oil cooler / filter setup? The oil cooler is pretty wimpy.

    I have, but I'll wait to see what the thermal load E85 puts on the fluids (oil & coolant) then I'll decide if a cooler is needed. I'm not a big fan up "upgrading" something that doesn't really need it. I will be re-routing the sensors and shifter cables that sit above the oil filter cap to make oil filter changes a bit easier.
