johnworden1 16 Posted July 22, 2020 Share Posted July 22, 2020 Would anyone have an otherwise junk fuel tank they would cut the fill neck off of so I could solder it onto the pictured tank? I would like several inches of metal beyond the solder joint remaining for trimming and fitting purposes. Also what is the thread at the pickup tube? Thanks. John Link to post Share on other sites
Surf City '38 250 Posted July 23, 2020 Share Posted July 23, 2020 Give Steve a call at DCM, (616) 772-1165, they make complete tanks, I suspect he would sell you a neck. From memory only, 9/16 double flare fitting, would have to wait until I can get out to the shop to confirm. Link to post Share on other sites

johnworden1 16 Posted July 24, 2020 Author Share Posted July 24, 2020 Ok Dave. The tank can be junk other than the neck. Thanks. Be safe on the road. John Link to post Share on other sites

John You bought parts from us before? You were doing a Dodge truck that the roof-dash was rusted? Link to post Share on other sites

johnworden1 16 Posted July 25, 2020 Author Share Posted July 25, 2020 I would also like to know what female thread is in the tank drain hole. A flare nut fits and a pipe plug does not. I would have thought a pipe plug was used. John Link to post Share on other sites
Surf City '38 250 Posted July 26, 2020 Share Posted July 26, 2020 Standard thread allen plug, 3/8 or 1/2 inch, for mine. Again from memory.... Link to post Share on other sites
johnworden1 16 Posted July 26, 2020 Author Share Posted July 26, 2020 Ok I'll try that. Thanks. John Link to post Share on other sites

johnworden1 16 Posted July 26, 2020 Author Share Posted July 26, 2020 Seems odd that it isn't a tapered thread plus it's a very shallow thread of only 3 or so threads. Once I figure out the thread I'll need a good fuel proof thread sealer. Link to post Share on other sites
ArticiferTom 277 Posted July 26, 2020 Share Posted July 26, 2020 May want to try brass pipe plug . Link to post Share on other sites

ArticiferTom 277 Posted July 27, 2020 Share Posted July 27, 2020 It is not inverted flare ? Is there any structure in it ? 1 hour ago, johnworden1 said: 1/4" brass pipe plug doesn't fit. Link to post Share on other sites
johnworden1 16 Posted July 28, 2020 Author Share Posted July 28, 2020 Drain hole not fuel pick up tube. Pick up tube is flared. Drain hole is not flared and 2/3 threads deep. Link to post Share on other sites
ArticiferTom 277 Posted July 28, 2020 Share Posted July 28, 2020 Sorry my miss interpretation . I just measure mine it is 1/8 NPT not 1/4 . it was forced to deep by PO and cracked so weeps now even with tape . 45 minutes ago, johnworden1 said: Drain hole not fuel pick up tube.

johnworden1 16 Posted July 28, 2020 Author Share Posted July 28, 2020 (edited) I'll try 1/8 NPT but I think it will be too small. Edited July 28, 2020 by johnworden1 (see edit history) Link to post Share on other sites
ArticiferTom 277 Posted July 28, 2020 Share Posted July 28, 2020 1/8 th NPT is about 3/8 OD of the threads with 1/16th taper . Get brass if you can . Any hardawre with plumbing should have where there flare and compression fitting are . Link to post Share on other sites
johnworden1 16 Posted July 28, 2020 Author Share Posted July 28, 2020 Problem solved. I was trying an SAE bolt I thought was 1/2"- 20 It wouldn't go. It was metric. A 1/2-20 bolt fits perfectly. I should be able to find a suitable drain plug with that thread. Thanks for the suggestions. John 2 Link to post Share on other sites
