the carter pump , the lower pressure one , is reliable and a long time proven design , but if mounted using their bracket ,it transmits noise to the frame Their little rubber grommets are a really lame attempt at fixing that . I agree aggravating noise . … I am experimenting with letting it hang by the rubber coupling hoses by securing them on each side 3-4” away from the pump by main bearing- like hose clamp blocks . Car not done yet I would use FI rated hose to get good reinforcement ( cord in the hose) . It ought to be a lot quieter I also see they came up with an in tank pump ( like an FI pump) that has the low pressure output for carbs.It is small. I bought one but have not tried it . It looks like it could be secured to our gas gauge float bracket . One does not hear the 50 psi fuel injection pumps in tanks … but seems crazy to use that 50 and a regulator , thought about that , too much to go wring in bad ways. but then saw this carb pump—- Interesting issue , I hope someone tries faster than I will get to it and reports back By the way there is an oil pump pressure switch used in late 70’ s dodge trucks 318 that can supply power to FI pump relay oil over 5 psi ,you use a tee I wire that from ign through a 1N4007 diode to the pump relay and also another diode off the start wire . Line on diode toward relay . 10 A fuse on power . j On Jul 17, 2025, at 7:30 AM, dplotkin@xxxxxxxxxxxxxxxxxxxxxxxxx wrote: -- For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang --- You received this message because you are subscribed to the Google Groups "Chrysler 300 Club International" group.
