dat240zg Posted March 4, 2007 Share Posted March 4, 2007 Just got my fuel tank back from Moyers (http://www.gas-tank.com) today and it really turned out nice. They did a whole list of things for me including: 1. Welded Brad's 240Z sump, 2. Deleted the factory return and feed lines and subbed an AN fitting, 3. Welded additional baffles inside the tank, 4. Repositioned the drain plug, 5. Reconditioned the tank inside and out. If anyone else is considering getting their tank redone, this is the way to go. $350 for everything and comes with a lifetime warranty against rusting. Jim is the guy to talk with - nice guy and fairly knowledgable about Z's as well. They received the tank and had it back to me within 10 days! Anyways, pics are worth a thousand words so: Now to mount the pump, plumb the lines and get this thing running! Bryan Quote Link to comment Share on other sites More sharing options...
jbk240z Posted March 4, 2007 Share Posted March 4, 2007 The tank looks great! Your Z is going to be awesome when done. By the way, did you ever sell that other Z #248? Quote Link to comment Share on other sites More sharing options...
dat240zg Posted March 4, 2007 Author Share Posted March 4, 2007 Nope. 248 is still waiting for the current project to be finished before I tackle the body work on that one. I'm at the collecting parts stage. Bryan Quote Link to comment Share on other sites More sharing options...
getZ Posted March 4, 2007 Share Posted March 4, 2007 What year is that tank from? I have 73 with a tank modified very similar, but the top vent tube come straight out the side on the driver side instead out the back in a 90 degree elbow. It was never a problem until I decided to cut out part of the spare tire well to make room for a second muffler. Then the outlet was running to close to the muffler. I bent the line to point backward, but it kinked. It's still functional, but I'm sure it doesn't flow as well now (not that it's going to really hurt me). By the way, the vent tube is a pretty big diameter hose, something like 15mm. You have to order ahead if you want it done quickly since the local auto parts store don't usually carry a fuel line that big. Heater hose will work for a short amount of time, but some hoses not rated for gasoline don't stand up for very long. I used an half inch oil cooler line I happend to have sitting around that I muscled on there, thank goodness rubber stretches. Quote Link to comment Share on other sites More sharing options...
dat240zg Posted March 4, 2007 Author Share Posted March 4, 2007 The tank is out of my early '70. You're right about the vent hose. When I bought the car the PO had used heater hose at some point and it was beginning to break down. It's since been replaced. Quote Link to comment Share on other sites More sharing options...
EvilC Posted March 5, 2007 Share Posted March 5, 2007 Hmm, this sounds like something I can do instead of going with the LS1 tank. Within the next week I have to know exactly what I am doing. I like the fact that the weld in baffles but I am wondering on the track will the car still be starved for gas in had cornering. I know with the stock tank everyone has told me you have to keep atleast half tank always. For this reason I was just goig to go with the LS1 tank......hmmmm Either way the tank looks great.....get that thing mounted so we can see =) Quote Link to comment Share on other sites More sharing options...
dat240zg Posted March 5, 2007 Author Share Posted March 5, 2007 Clive: From what I understand if the tank is baffled (like a '75 280) then there isn't a fuel starvation - or at least it's greatly reduced. The baffles within my tank are similar to a 280 tank and in addition, when the put on the sump they drilled 1" holes to add to the baffling affect. All this baffling is baffling.... Anyways, seems like less work than the mods needed for the LS1 tank. Are you going duals for your exhaust? Bryan Quote Link to comment Share on other sites More sharing options...
briann510 Posted March 5, 2007 Share Posted March 5, 2007 So they welded up the sending unit hole also or it on the other side of the finished picture? Im looking to mod existing tank and have the fill tube come out the rear behind the license plate instead of the side as the stock fill door and such will be covered by the YZ flares to be put on. Either mod the stock tank or run a fuel cell which I dont really wanna do for safety sake inside the car in case of being rearended. Quote Link to comment Share on other sites More sharing options...
dat240zg Posted March 5, 2007 Author Share Posted March 5, 2007 They left the actual sending unit hole, but cut out the factory feed and return lines and replaced them with a -6 AN fitting for my return line. They did a really nice job with the welding - they actually modded the outside of the tank in three different spots and looks slick.

1 tuff z Posted March 5, 2007 Share Posted March 5, 2007 bryan, it looks great. for my brain orientation-do the an fittings point rearward or forward? also, what is the purpose for drain plug relocation? thanks Quote Link to comment Share on other sites More sharing options...
dat240zg Posted March 5, 2007 Author Share Posted March 5, 2007 On the sump they're facing towards the rear. They moved the drain plug for free . It wasn't really needed due to the sump, but I didn't give them clear instructions on what to do with it, so they just relocated it to the side.

24OZ Posted March 5, 2007 Share Posted March 5, 2007 Very Nice indeed. I have a question, if they cut open the tank and add baffles then can I get away with not having them weld the fuel sump in? Quote Link to comment Share on other sites More sharing options...
dat240zg Posted March 5, 2007 Author Share Posted March 5, 2007 Good question. I'd bet that you could. Part of the reason that I had them weld in the sump was for the AN fittings for my fuel lines, but they could probably weld in the fittings w/out the sump. Because of the shape of the tank, I don't know if they could weld an -AN fitting low enough without the sump, but if you're staying with stock lines - feed and return - I don't see why it wouldn't work.

Jeff Posted March 5, 2007 Share Posted March 5, 2007 On the sump they're facing towards the rear. Can the sump be turned around so that the lines come out the front? I would prefer that from a routing and visibility stand point. Quote Link to comment Share on other sites More sharing options...
dat240zg Posted March 6, 2007 Author Share Posted March 6, 2007 I'll be honest, I'm not an engineer, don't even play one on TV, so my answer is just what I've gleaned from others. Based on a thread that I followed for a while, it looks like if you turned your sump around you could have a problem with fuel starvation under acceleration as the fuel moves to the back of the tank. I don't know if that would be a real problem under every day driving, but on the track I could see it causing problems. FWIW...

24OZ Posted March 6, 2007 Share Posted March 6, 2007 I am glad you asked that question Jeff as i always wondered the same thing and thanks for the answer Bryan, it makes sense. Quote Link to comment Share on other sites More sharing options...
EvilC Posted March 6, 2007 Share Posted March 6, 2007 That does make sense to me also. I think I am going to ditch the LS1 tank and give this setup a try. Worst case is that I will have to always keep 1/2 tank in the car. I am going to see how far into PA these guys are from NYC. Quote Link to comment Share on other sites More sharing options...
Jeff Posted March 6, 2007 Share Posted March 6, 2007 That does make a lot of sense and it hadn't even occured to me. Thanks for the reply. Quote Link to comment Share on other sites More sharing options...
briann510 Posted March 6, 2007 Share Posted March 6, 2007 Sumps/fuel cells always have the fittings in the rear, cept maybe a rare case for safety if it were to be rear ended. Quote Link to comment Share on other sites More sharing options...
z_cars_rule Posted March 6, 2007 Share Posted March 6, 2007 also regarding the position of the fittings on the tank, think about driving up a steep hill, you need more throttle and therefore more fuel, and the fuel would run back to where the fittings are. Going down the hill you have no such problem as you are most likely to be lighter on the throttle. Quote Link to comment Share on other sites More sharing options...
