Mr Gasket 4-7 PSI for Weber IDF too much pressure? Options

[Tdskip]

This for a car that us set up with a front trunk mounted fuel pump (prior owner) that I suspect needs the Facet pump replaced. I know the low range of 4 PSI is fine but am concerned that the upper range list on the pump is too much.

Thanks and hope everyone has had a good Saturday.

At about 5 pounds you will overcome the floats and flood the carbs with fuel. BTDT.

The pump will work but you will need to have a regulator in line.

(IMG:style_emoticons/default/agree.gif) for some reason my Carter/CB pump ran more pressure than the max listed unregulated with a quality gauge,set up the pressure to 3.5psi and got a small amount of spill over from the fuel bowls,reset to just over 3 psi and haven't had any issues since.
When I rebuilt my carbs I did a bench setup to make sure the float levels were to spec using the PMO level gauge,found this very handy as was pleased to see they were correct with the new washers and float valves from the kit,its also a good thing to measure the pump delivery on each throat.
Setting the pump delivery was a PTA due to the system on the Zeniths but got there in the end.
In summary pump pressure is important but float levels must be even also,good luck Tom.

Yes and yes, carbs Will require some fiddling and float levels are very important. Once they are dialed in (and it can be a process) they can be frustrating, but satisfying at the same time.

IMO float level setting are secondary after the right fuel pressure is within spec otherwise its an issue,some rebuild kits have "knock off" float valves which in my experience don't hold pressure very well,had this with a Weber kit ,put the original Weber ones in a issue was gone.
