hi everybody, Has anybody tried the Danchuk High capacity aluminum gas tank 25gal. or the larger 29gal. tank by Classic Performance Products. Right now I have standard 16gal now. Wasn't sure about the fit with frame and the exhaust issues. trying to pass gas stations Right now I have a GM crate 383 stroker, carb. If this new stuff will work I will have a near new 16gal gas tank left over!
I've been running the 25gal.tank for years. It's a game changer! One of the best decisions I've made after overdrive. I can get 15mpg on the hiway. I bought it when it first came out before the 29gal version, I would have happily removed my spare tile well for another 4gals. My exhaust pipes ran below the frame rails to start with so no mods were necessary. I average around 8000 miles a season and I often think when passing a truck stop "I remember gassing up there" before this tank.
We bought one of the CPP 25 gallon gas tanks for our 56. When we were trying to get it mocked up in the car we found out that the mounting angles were welded on in the wrong places which was making the tank impossible to install. We called CPP customer service ??? and then played email tag for several weeks with some of the most idiotic repair suggestions to make the wrongly made piece of CPP JUNK fit. They would not return any of my phone calls only email games with no results. We have spent A LOT of $$$$ on CPP parts for our car and this is the first part that we have tried to install. I certainly hope this is not the start of a lot more disappointment for us. There is a video on UTUBE that shows the very same problems that we are having. The extra capacity will be nice once we figure out how to get it in the car. If you do decide to get one of these tanks maybe yours will be built right. GOOD LUCK.
After watching that video I was reminded I had the same thing happen. The spare tire well required a block of wood and a tap with a 3lb hammer for clearance. And the filler neck of the tank rested on top of the frame with no room to push the filler hose on. (they really should angle the neck up about 10deg., there is room) my helper was quite the welder so he made a quick cut and notched the frame for clearance. The crossmember in the video does look wrong as mine fell right into place. Those 2 problems added about an hour to the install. I chalked it up to "sure fit custom parts seldom do". My sure fit Vintage Air install also involved home grown engineering to fit and function. When you consider its not hard to spend over a grand an a sweet stainless tank, I still think the CPP is a deal. I would never have a tri five with a 16gal. again.
Yes that is the video. There is a lot more fitment issues than actually show up in the video.We have been at four of the five Tri Five Nationals and have looked at crawled under taken pictures and measurements of several different cars that had this tank installed. When the tank is correctly made it fits as intended. Both the mounting bracket on the tank we have are just flat welded in the wrong places nothing fits as designed. The guy I played email tag with at CPP customer service ??? told me that video was A LONG TIME AGO but the date code on our tank is very close to the same time the video was posted. If CPP admitted this to me then they know they had a problem and won't do anything to correct it. I understand this is a custom part and usually some adjustments may be required, but with the cost of this and knowing they are wrong should correct the problem. I have been in this hobby since before High School and encountered of course many quirks over the years. Our $$$$ comes slow and hard. I as any one would expect to get what I pay for as being correct as advertised or having the problem taken care of by the seller. I don't think this is being unreasonable. I am just an OLD FASHIONED OLD MAN and thanks to my parents VERY PROUD of it.
