I found a Carter pump for sale that's from a 5.7 liter GXi. Mine is the 'PFI' type, which I guess stands for 'Port Fuel Injected' instead of TBI (Throttle Body Injection). I guess I should hook it up and check my low-pressure pump while I'm at it. No 'fuel cells' No ECM's at $1,500Ĥ) What would be involved in retrofitting to a carburetor? They run engines with carburetors, and can replace their entire fuel system for that. I guess I can test it on the bench, but it will be a pain in the neck.ġ) Does anyone rebuild these gizmos? Or is Carter the only game in town?ģ) Carter shows a two-stage pump, low pressure to high pressure, for the Mercruiser conversion of the 4.3 MPI, so I guess it produces the same pressure, for $179 instead of $700. Once I had the 'fuel cell' (marketspeak) off, I noticed the pressure test port on the low pressure pump, but it was too late to test it mounted. I have two fuel tanks, and it doesn't matter which tank. I checked for fuel running down the vacuum line, and also fuel in the return line, but nothing. By switching on and off, I could trick it up to about 35 Lbs, but still no start. Switch on, engine off, the fuel pressure at the injection rail was about 30 Lbs. Replaced the cap and rotor and plugs, ok spark.īUT. Ridiculously overpowered.īut it started to start a little hard, needing some throttle, then began backfiring while starting. The engine has about 700 hours on it, installed in a miniature Maine lobsterboat, a Repco 21, with a duoprop drive. Re: Year from serial number for Volvo-Penta
