SHORT VERSION:
RCI FUEL CELLS SUCK! IF YOU NEED A FUEL CELL GET ONE CUSTOM MADE.
LONG VERSION:
After finding yet another fucking leak on my fuel cell, i finally decided to just scrap my current one and start fresh. I have seen countless issues with RCI fuel cells leaking on the net after some searching due to my issue. After the pages of negative feedback about the quality of these tanks i hope no one else makes the same mistake i did by getting a RCI.
These tanks are very prone to leak at the welds due to the mounting tabs breaking, just regular wear and tare, and from vibration. I first thought it was due to how it was mounted. So i fixed this and remounted it. I got a new leak after that and even after i seal it, it just starts a new leak somewhere else.
A local speed shop referred me to this site:

Looking though there work, and the welds and materials are way BETTER than the P.O.S. RCI does. The material is thicker and welds are cleaner. Also there mounts are made stronger and wont break off like ALL RCI tanks do. There price is also comparable to most manufactures Best of all they make custom cells to your specs. I just finished a sketch of the cell that i will be running. I will be contacting them some time this week and will hopefully have there tank by the end of this month.
Sorry for the long post i am just pissed after having so many problems with a "quality" part that reputational companies (like summit, jegs, and most locals) sell.

At the very least i hope this post will make those of you thinking about getting a RCI cell think twice before you spend the money.
If all goes well maybe this company can also make some for the other members are looking for. I am sure they could even make a stock replacement cell to use your stock pump and keep the tank in the stock location. Just give more clearance, or even be able to run and external high flow pump for those that want some performance.
