thinking about new tank with in-tank efi pump

    I am seriously considering ditching my frame mounted fuel pump for my Fitech and going to a new tank with in tank pump. This would solve a couple issues for me, and offer a couple benefits.

    I thought briefly about drilling my old tank for retro fit pump, but drilling tank that had gas in it doesn't excite me, and either my bother or another buddy could use my new old tank as-is so it would not go to waste.

    Question becomes... which one? Looks like there are a few options out there... Fitech has one from HyperFuel, Tanks Inc is another, and now Holley has one also. Holley seems to be the most expensive option, but their tank is galvanized and powdercoated.

    What say you guys?

    I've been deciding on the same thing for awhile now.

    I think most go with the tanks inc setup.

    Areomotive has a new tank out with everything preassembled and the part I like is it uses the stock position for the fuel lines.

    OMG this looks perfect... was not aware of this offering... THANK YOU. The main reason I have been delaying (besides $$) was having to deal with fuel lines into the top of the tank screwing up my molded trunk carpet... this looks like a WINNER to me.

    Hyperfuel uses a 255lph pump and this one comes with a 200lph version, but I am thinking that should be more than adequate for my needs, I ain't running 500ci...

    That's the reason I was delaying it too. Wasn't sure I wanted to run lines in the trunk. Especially since I relocating the battery back there.

    They do also have one with higher lph too.

    ..

    I called Aeromach tech support, they assured me 200lph is fine for my mostly stock 289. My plans call for building up a 347 in the next year or 2, but even at best of 400hp he assured me the 200lph would cover that as well. I called Fitech and was able to order a few more push lock connectors and 5' of hose to bypass my pump and connect to the stealth 2 tank fittings... moving along... now I just gotta check the couch cushions to see if I can find enuf spare change to order the tank... that may need to wait until the holidays tho…

    my fuel pump and fuel lines run way too close to my exhaust for my liking, I heat shielded everything but still don't like it. cleaning this up is a big to-do on my winter punch list.

    Looks like they make a stock 16 gallon for the earlier models and the larger 22 gallon for the 69-70s. I used a stock 69 in my 65 fastback, so I would assume the 69 Aeromotive tank would work just fine? I like the idea of the internal pump, may have to put this on the list of things to change. Not a terrible price when you consider the cost of a new tank, pump and float assembly.

    Summit racing has them for $498. And they have a coupon for $50 off $500. Just Throw a couple connectors in the cart to get over $500 and the tank ends up at $450.

    That's a pretty clean new set-up. Fuel lines in the trunk are not really that much of a concern in terms of safety any more than the union of the tank to the filler neck. Actually less. With a high pressure pump you need to be using fittings and hoses/lines that are not at risk to leak or fail. Most important it the tank baffling to keep the pump submerged at all times. I'd like to see how everything is plumbed and connected on that new design in the tank. Seems like pump removal would be more of a chore.

    this pic is from their web site. Looks like they have a port in the top of the tank for pump replacement, but it also looks like a slight pita to swap it out.

    That's what I figured it had to look like inside. Depending on issue needing fixed, draining the tank would seem a fairly common requirement. Not the end of the world if at home (provided you had storage capacity for the volume of fuel) but not so easy out and about somewhere. With the top drop in with fittings on the top never an issue. I guess something worth considering.

    the pump drops in from the top of the tank, but I can't tell how the hoses are attached that run over to the stock location, and in the pic at least there doesn't seem to be much slack... but who knows what it really looks like in there. I figure they had get it in there somehow, so there has to be a way to swap it out if it ever fails.

    somewhere in the fine print I read the foam surrounding the pump is fuel resistant, I would feel better if it said fuel proof... but I think Aeromach has a pretty good reputation in the industry so I am not all that concerned.

    Areomotive has been selling in tank pumps for some time.

    I would not be concerned with the in trunk fuel lines. I just don't want to drill anymore holes or lose more trunk space. The way I look at I'm not building a monster motor, show car or trailer queen. It's a driver at best. So the ease of the stock location really appeals to me. Less fabrication and such.

    I would much rather have the fuel lines in the stock location as opposed to dealing with them in the trunk. No doubt they would be in the way in the trunk, plus more holes to drill in my precious car. The risk of having to drain the tank to replace the pump is minimal as I would expect a quality unit like this, with occasional use, to last a very, very long time.

    Does anyone know if the Aeromotive tank has a drain plug? Tanks Inc doesn't

    I don't think so, but I imagine you could add one before installing it.

    Yes you could weld in a bung, but how would you paint, plate, or seal it from corrosion? You'll destroy the coating on the tank in that immediate area. Anyone know a good product that will stand up to another 50 years of gasoline on the inside and weather on the outside?

    Stainless steel tank.

    Still can't tell if you can swap that pump without taking off the piece that fits in the stock sending unit place. If there is enough line slack to pull the pump up and remove the hoses without removing the other piece this looks like a decent part. And Ken, you never know when any part can fail. Even a new quality pump. I bought a spare Walbro to carry in my car just in case for any trips of serious distance.

    Oh don't I know that. But there is no way to carry a spare for every part that could fail, especially when dealing with efi, etc....so I carry a Mastercard and a tow card! But that being said, I do think that the failure of a high quality fuel pump is way down the list of my worries!
