NOBODY!\nSPA Turbo Composite 14:1 FMU\nUp to 14:1 adjustable gain rate \nFMU = fuel management unit\nSPA composite  Fuel Management Unit \nLightweight and virtually in-destructible.\nEthanol and Methanol compatible and SAFE  \nEasy installation\nFMU has a adjustable, boost referenced 1:14 raising rate\nFine tune the fuel pressure that your motor will need while under turbo - boost.\n8mm inlet and 8mm outlet fuel ports  \n1/4\" boost reference port\nAdjustable from 10 psi to 100 psi fuel pressure \nAll SPA Turbo FMUs can also be used as fuel pressure regulators. \nIn other words, if you need a fuel pressure regulator, and are thinking of later upgrading to a turbo system, save money and get The FMU instead of just the FPR.  \nWe've had a few questions about how these work, so here's clarification: \n\n \n\nInitial line pressure is adjustable from 10 psi to 100 psi - boost referenced fuel pressure increase is also adjustable. \nThe boost referenced pressure increase is adjustable from 1:1 to 14:1 meaning that the fuel pressure will increase proportionally with an increase in boost.\n\n\nHere's 2 examples: \n\n\nIf you are running 10 lbs of boost and 1:1 ratio, your fuel pressure will increase by 10 psi. \nIf you increase the boost referenced ratio to 14:1, your fuel pressure will  increase by 140 psi. \n\n\nIf your initial fuel pressure is adjusted to 100 psi, your total pressure in the first example would be 110 psi and 240 psi in the second example. However, 240 psi would require a heavy duty fuel pump. \n\n \nFuel pressure regulator bracket\n \n\nAllows perfect fixation of the fuel pressure regulator in the desired location.\n\n\nFits all SPA Turbo fuel pressure regulator.\n\n\nCan also be used on other fuel pressure regulator with fixing holes as described in the \"Technical Drawings\" tab.\n\n\nMade of high quality galvanized steel.\n\n \n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/VLRPC01-CVLSPT04_56bb9188-b8a0-4f28-8482-6f17a6ec93cc.jpg?v=1764104397","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/VLRPC01_2.jpg?v=1730997098","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/VLRPC01_3.jpg?v=1730997098","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/VLRPC01_1.jpg?v=1730997098","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/CVLSPT04_2_eccf73cf-bd16-4b36-9df3-e8d9448904d1.jpg?v=1730997098","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/CVLSPT04-TEC_14adeefd-acab-48e7-9ba5-f6504138d93a.jpg?v=1730997098","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/FMUINJETADO01.png?v=1730997098","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/FMU-FPR_Prancheta_2_jpg_b4adb0e2-dd82-447b-9b24-474cc1b9479e.jpg?v=1776543764"],"price":64.9,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.166Z"},"share_url":"https://firestarter.network/l/lst_ipM-Nwu_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
