I have a Beautiful Indy 500 EFI and it did sit for 10 years with rotten jelled fuel in the tank. I removed tank installed new filters and lines and the machine runs great for about 1-2 miles but after that if you open it up it dies. It will start if you allow it to sit for a minute or two it starts and runs again. I have looked for a new fuel pump part # 3084082 and found one but the price is $311.00, I paid $250 for the sled. My question is can you use a summit racing brand if it produces 40 psi?? Thank you for reading this, and I appreciate you help!!
