{"product_id":"nostrum-gm-lt4-high-pressure-fuel-pump","title":"NOSTRUM GM LT4 High Pressure Fuel Pump","description":"The Lingenfelter NOSTRUM GM LT4 1150-250 High Pressure Fuel Pump is a universal HPFP core designed to offer enhanced performance over stock units. It features an 11.5mm piston and is capable of sustained 250 bar rail pressure, significantly exceeding the capabilities of the production GM LT4 pump.\n\nThis high-pressure fuel pump (HPFP) shares a similar outline to the stock GM LT4 pump (part numbers 12711668 or 12694529). However, it differs with an AN06 male threaded low-pressure inlet, replacing the 3\/8\" SAE quick-connect fitting found on the LT4. This AN fitting allows for application-specific adaptation using standard AN fitting hardware.\n\nThe pump's specifications include a piston diameter of 11.49 mm, a maximum piston travel of 10 mm, and a maximum operating pressure of 250 Bar (25 MPa \/ 3636 PSI). The displaced flow per cam revolution is 1865.44 mm³, with a high-pressure fitting spec of M14x1 Male Thread with Inner Female Cone and a low-pressure fitting spec of AN06 Male.\n\nIt is important to note that this universal pump does not include the accessories and hardware associated with engine installation. For single-piece GM LT4 service parts that include accessories and hardware, customers should refer to their local GM parts center. The Lingenfelter Nostrum GM LT4 1150-250 High Pressure Fuel Pump is manufactured by Stanadyne.","brand":"Lingenfelter","offers":[{"title":"Default Title","offer_id":52686623932728,"sku":"L250","price":8750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/658282242.png?v=1784875399","url":"https:\/\/store.motormia.co\/products\/nostrum-gm-lt4-high-pressure-fuel-pump","provider":"MOTORMIA","version":"1.0","type":"link"}
