ttodhunter Posted November 10, 2010 Share Posted November 10, 2010 Hi, I performed the POR-15 Fuel Tank Repair and now I'm having an issue... I went to try and start the car and found that no fuel was getting to the rails. I checked the fuel pump, seized. Took it apart, cleaned and tested it. That works fine now. Hooked everything back up, hit start with the starter disconnected, heard the fuel pump working and still no fuel. I pulled the supply line off and, after cleaning it up a bit, tried to blow through it. I can not blow even a bit through it. I guess my question is: Can the sealer in the POR-15 kit seal the fuel pickup? If it has done that, is the tank worthless now or is there a way to fix it? Thanks Quote Link to comment Share on other sites More sharing options...
jc052685 Posted November 11, 2010 Share Posted November 11, 2010 Pull out the pickup and inspect/clean it Quote Link to comment Share on other sites More sharing options...
ttodhunter Posted November 11, 2010 Author Share Posted November 11, 2010 Wouldn't I have to cut open the fuel tank to do that? From what I see, the pickup line attaches to a hose fitting that is welded in... Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted November 11, 2010 Share Posted November 11, 2010 Is it me, or is that fuel tank diagram have the fuel level sender on the side... Quote Link to comment Share on other sites More sharing options...
ttodhunter Posted November 11, 2010 Author Share Posted November 11, 2010 Yes, it is on the side. It's got an arm that floats up and down on a pivot from there. Quote Link to comment Share on other sites More sharing options...
ttodhunter Posted November 11, 2010 Author Share Posted November 11, 2010 I just got off the phone with POR and we came up with a possible solution. They sell a POR stripping solvent that will dissolve the hardened sealer. The idea is to take the tank back off, empty it and pour a tablespoon or two down the pickup line. I'll have to monitor when it frees up and immediately pour water into the tank to neutralize the solvent so it doesn't damage the rest of the sealer in the tank. Wish me luck and I'll let you all know how it turns out... Quote Link to comment Share on other sites More sharing options...
ttodhunter Posted November 15, 2010 Author Share Posted November 15, 2010 Well, the POR Strip is pretty strong. It pulled all the paint surrounding the line within a couple of seconds. It has loosened up a very small bit inside of there so that the fluid drains but really slowly. Blowing through it is like trying to blow through a pinhole. I assume that it should blow through freely, does anyone have any experience with blowing through the fuel pickup? Quote Link to comment Share on other sites More sharing options...
Geking Posted November 16, 2010 Share Posted November 16, 2010 I pulled the fuel pickup line to drain the last bit of gas once. It flowed out like it was going through a McDonald's drinking straw, so you have more to dissolve. Quote Link to comment Share on other sites More sharing options...
ttodhunter Posted December 13, 2010 Author Share Posted December 13, 2010 Just in case anyone cares or comes across this problem themselves, this is where I'm at. I couldn't get the pickup to flow anywhere near enough, so I figured the tank was basically scrap metal and got to cuttin'. Looking at the diagram and visually inspecting the pickup tube, it appeard to go in a bit then hook a slight right. So, I busted out my cutoff wheel and cut me a hole. This ended up almost directly above the pickup, but I did end up cutting through one of the breather lines... Hopefully that wont be an issue. I soaked some paper towels in the stripper and shoved them alongside the pickup. After a few applications I was able to peel a layer of sealer off of the entire pickup. Nice. I cleaned up the tank and cut a piece of scrap metal (from the old spare tire well) to fit over the hole and proceeded to JB weld that on. Another side note: In the FSM, it says that if you drain the tank completely you will have to top it off in order to prime the pump. That is absolutely true. 5 trips to the gas station with two 2 gallon gas cans (just over 17 gallons), everything seems like it works.

BLOZ UP Posted December 13, 2010 Share Posted December 13, 2010 What's the base of the pickup have on it? Is it a screen--like a oil pump pickup? What year is that tank? Quote Link to comment Share on other sites More sharing options...
ttodhunter Posted December 13, 2010 Author Share Posted December 13, 2010 The base is a canister with a very fine mesh screen around the sides, probably a bit finer than the oil sump. This is on a 76. Quote Link to comment Share on other sites More sharing options...
Snailed Posted December 14, 2010 Share Posted December 14, 2010 Jb glue just isn't a safe way to patch that hole. Quote Link to comment Share on other sites More sharing options...
Graphitez Posted December 14, 2010 Share Posted December 14, 2010 I am so glad i don't have to go thru all this. I dropped my tank on my 76, There was no rust inside at all. The outside had some light surface rust, i just got it back today from the sandblaster. Time to por-15 the outside,then hang it back up. I was not aware you had to fill it to prime the pick-up tube,thanks for the info. Quote Link to comment Share on other sites More sharing options...
Pharaohabq Posted December 14, 2010 Share Posted December 14, 2010 Alternatively you can pull loose the hose from the fuel pump and pour fuel down it with a funnel, clamp the hose shut with some vice grips while you reconnect the fuel pump, and let it loose, then try starting, the fuel pump should then pull enough fuel through to make it all good.

cd1105 Posted December 15, 2010 Share Posted December 15, 2010 did por-15 give to any advice on how to prevent this? i'm about to to seal my tank with the kbs coating kit, and i would like to prevent this is possible so i don't have to go cutting into my tank.

ttodhunter Posted December 15, 2010 Author Share Posted December 15, 2010 The only thing I can think of is to make sure to blow through the pickup tube -hard!- a few times while it's drying. It should blow through fairly unrestricted. Quote Link to comment Share on other sites More sharing options...

280chisel Posted December 24, 2010 Share Posted December 24, 2010 i did the same thing with the eatwood gas tank kit. the car would run sputter then cut out. i ended up cuttin the tank open and re pluming and welding it shut with a mig. all is well now.

adivin Posted September 12, 2021 Share Posted September 12, 2021 Crap, I think I am in this same situation now. Wondering what the best approach is. I should probably start conservatively with the stripper. If I have to cut the tank, what is the best approach for re-plumbing? Quote Link to comment Share on other sites More sharing options...
Mayolives Posted September 13, 2021 Share Posted September 13, 2021 I'm not sure what your question ("situation") is. I have used the POR 15 fuel tank cleaning system 2 times and it worked great. If you followed the instructions and made sure the pick up plumbing was free and open, all should be well. What exactly are you having a problem with?
