  • Filler cap polymerization

    Has anyone else had polymerization occur on their filler caps? I have the 80 gallon smooth sided tank and have large amounts of crud build up on the inside of my filler cap. I clean it every time I fuel up but fear that chunks of this stuff are falling off and being sucked through the pump and causing my pumps to keep failing. I guess the solution would be an all aluminum filler cap. Does anyone know where to get one of those?

    I take it you have something other than the V3? It has a prescreen to catch that kind of crud before it makes it to the pump. It would be adviseable to get you an inline filter on the pickup line...a screen type. I remember Jason had some that were clear and easy to take apart to clean.
    As far as your filler cap, what material is it made of? If its steel, it will polymerize the oil. The RDS tanks Jason sells from Northers tool have a plastic made cap and work fine.

      Yes it is a v2 and yes it is one of the RDS tanks, but it came with what I guess is a steel cap with a chrome top. I would love to have one of the inline filters. My only hesitation to this point in getting one of the aftermarket ones has been the possibility of making it worse if the filter is made from steel also.

          the screen is stainless i think and doesnt have a problem with polymerizing, ask Jason to send you one.
          Call RDS and ask them to send you a plastic filler cap.

            Thanks Clay, I will do both of those things. The main reason I started thinking in this direction is to figure out why my system keeps burning out pumps. Maybe those things will help.

              How about a locking filler cap? I can only imagine some drunk at a concert relieving himself in the tank in the back of my truck.

              Granted you have to be over 6' to see in the back of the truck, but that didn't stop a bunch of guys from hopping into the back and stealing my beer and coolers.

              Once I relocate the tank below the truck it won't be a problem... but I'd like the peace of mind. I'll also be placing a box over the lines. Rubber hoses are just too tempting for some, I can only imagine someone ripping them off the box.

                Unless your not filtering your oil at al, this is likely why your burning up pumps. Should take care of the issue.
                Reason i say that is i have known a couple different people who pumped oil straight from the dumpster into there tanks and were letting the donaldson do all the filtering. Problem is when that corm meal or burnt french fry hits the pump, it will lock it up.
                Jason himself has done this as well.

                A locking filter cap would be nice but i'm not too worried about it.
                A cover for my hoses would be a very nice addition to my tank though!

                  I'd be interested to hear the locking filler cap options as well. I've had the same thoughts as Jack on someone sabotaging my vegi tank. I'm still planning on coming up with a cover for the hoses as well.

                    build your hose cover to also cover your filler cap and have a lock on it.
                    I don't know why anyone would be worried about anyone sabotaging there vegi oil tank though....

                      Yeah, if I built one, I'd have it cover all of them.

                      Haha...well, I don't have any enemies (that I know of), but you never know about folks these days. People do some really ignorant stuff.

                      If a cheap, locking filler cap keeps me from killing my high $$$ PSD, I think I'd go for it.

                        I do final filter through the same donaldson filter that is on the truck just before hitting the tank. As for the locking cap, I got the 80 gallon smooth side tank and cut the bottom out of a toolbox to fit over the whole thing and lock everything. The only thing you can see is the bottom 6-8 inches of the tank. I will take pictures of the polymerized cap and the toolbox and post if it ever quits raining here in North GA- not to complain, we need it!

                          When I make one I'll show you guys.

                          I'm also going to be making a V3 cover. Should help keep it hot, and clean. I can't stand seeing that much money under my truck and then go through a puddle

                          I'll keep you guys updated.

                          Don't get me wrong, I'm not constantly paranoid... but it only takes one instance of someone pissing in your fruit loops for you to lose most of your faith in humanity.

                            I guess you guys are drowning over there too huh? We've gotten quite a bit of rain over the past few days.

                            But, like you said, I'm not complaining - at least I don't have to water the yard this week.

                              I thought about a V3 cover as well. Maybe something louvered to ensure it doesn't get too hot, but still protect it from debris, rain and dirt from the front wheel.

                              Post up whatever you come up with. I'd like to see it.

                              Thanks!
