Fuel tank sump by Competition Engineering C4041. The Competition Engineering fuel tank sump is manufactured from 18 gauge mild steel for ease of welding and features two pre-welded 1/2" NPT bungs to ensure adequate fuel flow. Measures 11" long by 3" tall by 7 3/8" wide. All measurements are inside measurments and do not include the flange. Designed to fit onto stock fuel tanks or custom made tanks. Weldging required for installation. The problem with most factory fuel tanks is that they were never designed to provide the fuel required by a high horsepower motor under hard acceleration. Most factory gas tank pickups are located in the front portion of the tank, allowing the fuel pump to ingest air during acceleration. This can cause a moementary loss of fuel pressure during accleration which can be enough to make you lose a race. You can eliminate this problem by installing this Competition Engineering fuel tank sump. fuel tank sump Competition Engineering C4051 Competition Engineering 4051 Order quickly and easily over the internet on our secure YAHOO! system 24 hours per day or talk to a real, live sales person at 419-331-2470 during our business hours.
