tested my gas gage and it works!

hoggyrubber · February 2013

i am going to get my gas tank cleaned out soon and get it installed soon. today i ran the wire for the sending unit and while it was out of the tank thought i would test the gage/ sending unit. i was real pleased it worked and accurate too. the tank looks clean as a whistle, but i tought i should take it in and get it boiled out for safely sake. they say the put a coating on the inside that lasts for a long time. i have heard bad things about it coming off and clogging things up. not from this place but from others. what do you guys think any opinions? i had one guy tell me have a alum tank make, but i hate to spend that kind of money.

I just reinstalled my tank yesterday in the 53 coupe, after cleaning & checking it for any possible leaks it's in good shape. It did sit for many years & the vent tube & pickup tube were plugged so after all that and a new sending unit I feel it should do the job. I think the coating thing could be a problem later as all I've read suggests just what you said. If it ain't broke???????? good luck. Ron

I think coatings have gotten pretty good, and like anything prep is key. Coating a dirty tank, bad idea. One of the local radiator shops here cleans and coats gas tanks, I'm going to have them do my next one, quoted $200 range depending on the condition

I had mine coated... bad idea! Cloged up the pick up tube, fuel filters,ect. They keep changing the formulas of gasoline, and some of it eats the coating. Never again for me!

I coated my tank about 400 miles ago and have sence replace the fuel filter . I cut open the old filter and found no trash of any kind in it.
I should have tested my new sending unit as you did because I can not get my guage to work!!!New wiring to tank,grounded to the frame and tank. Temp guage works?? All I can think of is that the new sending unit is at fault but disconnected the wire going to it and grounded it and the gauge did nothing but stay on empty. I guess I will have to pull the sending unit and see if I broke it installing it or what?

Do not have any gas tanks coated inside. With todays gas, 10 and 15 per sent Alcohol it will soften and ruin filters and fuel pumps and carburetors. The 15 percent can ruin new cars with fuel induction systems as it turns to water if left to stayed parked any length of time. Walt.

My Essex was coated 25 yrs. ago with no problems. My 37 Terraplane was coated 15 yrs. with no problem, and my 39 and 17 have been coated with no problems. So, what's the problem?

charles4d · February 2013

I used Eastwood gas tank seal never had a problem with any gas tanks that were sealed even with new the gas formulas trick is to get it real clean first cost a little bit but you get what you pay for

RonS · February 2013

Seal or not? Does your tank leak? What does the INSIDE of the tank look like? Any rust? If there is any rust that will be a weak spot and the modern fuels( that absorb water) will eventually eat through the untreated metal. Kinda like enamel on your teeth. Thats the place most likely to get a cavity if the enamel coating is missing. No rust inside? You may wish to leave it, but if you plan a tour, pick up some gas/oil sealant at a Ace Hdwr. Keep it it the trunk just in case a pinhole sprouts. It happened to me on an AACA show some years ago... instant disqualification. However, I really don't know how you can be sure of the inside condition. The new sealants will last longer than you, IF applied properly. A local shop applied mine and the sealant missed a small spot, hence the leak. Not properly. Soo... it's your call.

7 years for me,who knows how long for the PO. No issues here,open pickup tube (no screen/sock) and never an issue. Mine came from a Renu franchise, coated inside and out.

I sealed the tank in my 51 Pacemaker 20 years ago and so far no problems. The tank was in good condition on the inside. Followed the directions as one should ( not like us guys usually don't). I bought my kit from POR 15.

wow! one vote no, one vote yes, one vote no, one vote yes.

( well i don't know what to do. not trying to start a argument or anything. the condition of my tank really suprised me, it was super clean with no rust i could see at least on the sending unit side of the baffle. i did remove the line going into the other side and what i can see looks pretty good. i want to have it cleaned either way. i guess i just hate to take it in and not even know what they will be using to do it. also you can do the same thing twice and get 2 different results.
maybe just having it cleaned is the safer route. i mean if all the no coating would do is eat thru the tank faster. if that happens it happens. then it might be time for the aluminum tank. but i hate to hae it out and not do something i can to prolong it's life. that coating coming off and cloggin stuff up sounds pretty bad. pin holes in the future is scarry but not that bad.
is there a way to clean it myself at home? there i go again trying to cheap out.

Bottom line, you asked "what do you guys think any opinions?"

From the responses the folks who come here have a variety of good and bad experiences. Guessing, there is also a variety of sealers and techniques being used to seal the tanks. One of the responders noted the alcohol content of today’s fuels and its effect on fuel delivery systems. If your tank is "clean as a whistle”, why add anything to the tank? Use it as it is and when and if there is problems correct that problem. Sealing a clean tank seems to be counterproductive. The current gasoline formulas will eat up or destroy much of the other OEM pieces in the system. Instead of sealing use those dollars to change the rubber and plastic parts of the fuel delivery system to alcohol resistant replacement materials. Your reliability will go up and when and if the tank needs to come out soldering holes is a better fix than sloshing in a sealant. The truth of the matter is removing and replacing the fuel tank is rather easy task.

Por 15 on the 47 C8 after having the tank boiled. Had enough left over to do two motorcycles. Thinking if if you don't seal it , in a couple years you will be back where you started. Doug

Geoff · February 2013

If you have the tank out, pour half a gallon of gasoline in it, slosh it around, and pour it out into a clean receptacle. If there are specks of rust or gunge in it, then have it treated, Otherwise leave it alone. My two cents worth. My hornet, Jet, and Essex have never had the tanks out or treated, and nothing ever comes through to the filter. I did treat a 1922 Essex tank with POR15 tank sealant which is a three-step procedure - clean, neutralise, and treat, 15 years ago, with no repercussions, but I think the jury is still out on how ethanol will affect these treatments.

What Old Farmer says to me , is the best advice, that I adhered to. I had my tank rodded out, cleaned in 2008. For awhile I had to change filters. Now all my filters are clean. I use nothing but Premium gas now. Filters have been clean for 4 yrs. Did Hudson sell their cars with Gas tanks sealed with Sealants in 1920-1954?
I don't remember my 51 Hornet having any fuel tank problems, back in the 50's. I would not
put anything inside a gasoline tank other than the sending unit, and gasoline top grade.

hoggyrubber · February 2013

no, don't get me wrong, i am glad for all the advice. i was kidding about one vote no, one vote yes. i think i may try Geoff's idea and see what comes out. if it's clean i may just rinse it a couple of more times and run it.

SuperDave · February 2013

I second Geoff's advice. (as usual) If it ain';t broke..don't fix it.

tested my gas gage and it works!
