Posted By Discussion Topic: Fuel Tank Cleaning- Any Ideas? -- page: 1 2     supereal 05-18-2010 @ 2:35 PM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 Mine also came from Yogi's, and fit well, except for the absence of a dent on the forward side to clear the shock mount. My '47 has the mounts that clamp to the cross member, and it took some changing. Of course, the caged nuts on the body mounting tabs were shot, but we also worked around that using regular bolts. My tank has the vent that fits up in the left rear fender, a different, but nice feature. There have been some comments about problems with fitting Drake's steel tanks, but it may just be that the whole job is somewhat tough due to the lack of working room around the tank. parrish 05-18-2010 @ 7:32 AM reply profile send p.m. Member Posts: 349 Joined: Oct 2009 Supereal: I bought mine from Yogi's based on your 47 use. I haven't used it yet due to a repaint and shock work, but I did pop it up in the cavity and it fit really well and seems to be of good quality. I have heard of the repo steel tanks being a little taller than original, which is a tight squeeze to start with... supereal 05-16-2010 @ 9:37 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 I suspect you are right about old Henry. He had a deep interest in the use of plastic in car construction, and actually had at least one such body made. There are photos of him swinging an axe against a trunk lid. Later experiments, such as Saturn, showed the durability of the material, but it never seemed to catch on. My plastic fuel tank has a built in baffle in the center. parrish 05-15-2010 @ 7:31 PM reply profile send p.m. Member Posts: 349 Joined: Oct 2009 I like to keep my Fords original as well, but I will usually rationalize some decisions (such as trying to fix a steel gas tank with internal baffles that will never come clean with a sloshing approach) this way...If Henry had been able to produce a nice poly tank back then, he would never have used metal! Make him proud! jdpears 05-15-2010 @ 11:54 AM reply profile send p.m. Member Posts: 11 Joined: Dec 2009 replace the tank and the complete fuel sytem. i battled this problem for 8 years. scared to drive anywhere out of the driveway. now i would take the old '46 around the world and feel safe as i would in a new one. i used a steel rep.. tank.don't short cut anything. supereal 05-15-2010 @ 8:57 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 Depending on the tank, you may have to add an extension to the float arm to get a true reading. We use Drake's replacement senders with no problems, but be sure to add a ground wire to one of the mounting screws. The primary reason tank cleaning usually doesn't work is that evaporated gas leaves a varnish-like crud in the tank that defies most solvents. When storing your car, either use a storage product in the fuel, or fill the tank completely to reduce air that aids evaporation. ford38v8 05-14-2010 @ 9:35 PM reply profile send p.m. Senior Posts: 2774 Joined: Oct 2009 47Fordor, The new tanks won't physically accept the original sender unless modified. The repop senders don't provide a full range of readings E to F as the original senders did, so you must decide at what point your gauge should read your tank. I have mine set to accurately read the E side, so that whenever the reading is less than F, I know I should stop soon for gas. Alan trjford8 05-14-2010 @ 7:44 PM reply profile send p.m. Senior Posts: 4232 Joined: Oct 2009 The repo sending unit will work with your gauge or you can modify the original unit to fit the new tank. I recommend that you buy a new tank. By the time you have the old one boiled out and you purchase the "sloshing"compound you will have spent almost as much as buying a new tank. When you clean an old tank, you still have an "old tank". Rust can reform and the coating has the potential to come loose. Norm 05-14-2010 @ 5:39 PM reply profile send p.m. Member Posts: 85 Joined: Oct 2009 I have used a new sending unit in an original tank with an original gage ('48 F-1) - no problems. Just be sure that you bend the float arm to suit your tank. Norm 47Fordor 05-14-2010 @ 3:45 PM reply profile send p.m. Member Posts: 72 Joined: Oct 2009 I'm curious: what is it that makes the old sending unit not work with new tanks? I never heard that the old gauges wouldn't work with new sending units. Can anybody confirm/contradict this? Chris
