  3. Fuel tank options?

    in 1965-83 Avanti

    Posted

    Hey all, I need a new tank for my '77.  I've been in touch with Bob at AvantiParts.biz, and while he promises that he's getting a new batch soon, he's been telling me that for months and still no action (he also never actually gets back to me when he says he will, I have to call every time, which is frustrating).  Does anyone know of another good option for a new tank?  I could possibly go down the repair route, but the shop I'm working with is pretty skeptical about it.  But now that it's been months without any success with AvantiParts (despite their repeated assurances of "two weeks") I might be up for anything.

    I'm in Chicagoland, if it matters.


    Thanks!

    I should add that the fuel is fresh.  We siphoned out the old fuel, added a few gallons of fresh, then lost at least two or three gallons to leakage when we pulled the fuel line off the pump (fuel was just pouring out and we had to cork it until we got a brass plug in there).  Then, when we finally pulled the plug to install the fuel line into the pump last night, nothing came out... which makes me think the tank slowly drained over the past few months.

    Hey everyone, it's been a while!  We finally got a carb, but the fuel line was fused to the old carb, so it took us another couple months to source the right line from Summit, then another couple months to get it installed.  The engine fired right up and ran BEAUTIFULLY for about 30 seconds, then puttered and died.   My neighbor thinks the fuel pump gave out right then, although he also mentioned the rust/clogging issues that people have mentioned here.

    I don't have much time to spend tinkering with this thing, as I have a young daughter, a busy wife, and some sick family members, so my time is precious.  Dropping the tank is really not an option.  Given that, what would you all suggest would be my next steps to resolve this? 

    Option 1 is just to swap the fuel filter and see what happens. 

    Option 2 is to try and feed the filter from an external gas canister (run the supply lines from the pump into a container of clean gas) to isolate the pump and diagnose from there. 

    Options 3 is replace the lines, the filter, and possibly also the pump, all in one go, and see what happens. 

    Option 4 is to just take it to a shop and let them figure it out.

    thoughts?

    Ugh, we tried that, and the bends are a pain in my ass.  Maybe I need a better bender, because the one I bought from the local parts store was a POS and caused all sorts of kinks, even with very careful pressure.  Got any benders you recommend?

    Does anyone know what fuel line/tube would be the right match for this engine, between the carb and the fuel pump?  I bought this one (https://www.summitracing.com/parts/CST-CAC1016-OE), which is an exact match for the top 3/4, but the bottom end near the pump is too long and some of the bends aren't right... this one (https://www.summitracing.com/parts/cst-cec1029-oe?rrec=true) looks closer, but I'm wondering if anyone has an easy answer without me buying another one.... might be this one (https://www.summitracing.com/parts/rsd-mpc7701s/year/1977/make/chevrolet/model/monte-carlo), too, but it's not in stock for a month or more.

    Hey all,

    So we got into the carb replacement yesterday.  Had to cut off the fuel line at the carb, as the tube was fused to the flare nut and we couldn't get it loose.  We tried to bend a new one, but our bending tool was a POS, so I ordered this one from Summit racing, which looks like a match: https://www.summitracing.com/parts/CST-CAC1016-OE

    Anyway, when we removed the flare nut from the fuel pump, fuel started pouring out.  Is that normal?  I assumed it would only leak the fuel from the line and in the old carb, but it was at least a half cup or more and still flowing strongly until we got it plugged.  The other two lines into the fuel pump (assuming a supply line and a return back to the tank?) also let fuel flow out of them easily, as if it was just pouring out of the tank.  One of those lines (the one closer to the carb line/tube) had a rubber section between the fuel pump and the hard line back to the tank which was all broken down, so we replaced that 6" rubber piece, but we had to keep a finger stopper on the fuel pump as well as on the fuel line to keep them from flowing.  I was under the impression that without the sending unit or fuel pump actually operational and powered up, very little fuel would leak, but clearly I'm wrong.  How do we keep fuel from getting everywhere as we work on the fuel lines???

    Thanks, all.  We decided to go with a rebuilt one from National Carb for the time being, but if that gives us any trouble, Quadrajet Power really seems like they know what they are doing.  I just couldn't wait 12 weeks for them to rebuild it right now.

    edlebrock #2696 appears to be exactly the same as #2697 and retails @$29.95 vs $78.95 for the #2697. the later does include a couple of fittings, a filter and some fuel line, but an uncharge of 49 bucks??? am i missing something? 

    The 2697 includes a fuel line kit.

    If your engine is a 305, I'd probably go with a 500cfm Edelbrock....If it's a 350, I believe I'd buy a 600cfm.   (Not sure of the Edelbrock specific part numbers, but all that info is available on their website.:)

    And yes it's the 350.  Ok, thanks for the info, mfg.

    Hi all,

    We're working on getting my grandpa's '77 running after sitting for many years in his garage.  There was nearly a full tank of gas that we siphoned out, and replaced with premium.  Threw in a new battery and a bit of gas in the carb and it cranked right over and caught a few times.  We couldn't get it to stay running, and our car restorer buddy said the lower jets (I think that's what he said) were probably clogged and the engine was running lean.  His thought was to just swap carbs, but I'm finding out that new quadrajets are nearly impossible to find.  So my options are (i) ebay for a decent used one, (ii) pay someone to rebuild, or (iii) something else??  What would you all recommend?  I see some "recently rebuilt" quadrajets on ebay fo $200 or so, is that worth the risk?  Or would it be better just to pull it and take it to someone to rebuild?  Also, if I buy one, what do I need to look for to make sure I get one that matches this vehicle?

    Any other advice is welcome!  Thanks much.
