Hello,
I'm working on a long term project. I saw a an original factory solution I liked on a 1979 Eldorado and thought it would work well on my Impala. They used what looks exactly like "ACDelco GF62P Professional Fuel Filter" but I was wondering what the maximum working pressure is which it was designed for.

More simply has anyone used this for a modern fuel injection system prior to the regulator? I would like to use it near the tank after the in-tank pump. I intend to use a Walbro 255LPH pump.

This is what it looks like (Amazon photo but rotated in the direction mounted on the Eldorado).

Thanks,
Scott

I saw some similar style fuel / water filters for marine use which look like the canister might be a little more robust (one was similar to an oil filter).

I like the fact that the canister threads off like an oil filter as opposed to the inline style with entrance/exits out either end. Is anyone using anything similar which you would recommend?

Does anybody know the maximum output pressure of the Walbro 255LPH pumps?

Thanks,
Scott

You didn't say what the application was or your intentions here.

If the filter is on the high pressure side of the pump, then you can use a 10-20 micron filter, with a flow rate suitable for your pump, power level, and fuel used.

The "high pressure" 255LPH pumps are rated at up to 120 psi. Not sure on the others. Remember that system pressure will be controlled by the pressure regulator with this pump, not the pump itself. There is no pressure control in the pump itself. You have to have a regulator. Most OEM late model systems run at 58 psi.

Hi Rick,
I tried to describe where it would be used in relationship to the other components in the original post. I would like to place it prior to the regulator and near the tank so as you wrote it will be subject to the full output of the pump in that position. I realized that part but I was not aware of what that pressure could be and if there is a canister style which can withstand that pressure plus a safety factor of course.

Thank you for clarifying the rated pump pressure as well as the comment on the typical OEM system.

I was hoping to find somebody else who may have tried a similar style filter. I like that style just because they seem easy to service without dumping a lot of fuel like the barrel inline ones seem to.

Thanks,
Scott
