Fuel Filters

IMO, It would be best to run two of these in parallel. They are somewhat restrictive.

I would like to see some data to back up this statement. This filter has been used, in conjunction with a Walbro 255L/hr pump, to feed a 600HP (flywheel) 496 big block chevy. I suppose if you had a 1000RWHP engine you would need something else, but for the 90% of builds out there, this filter will work just fine.

As for using the 2001 truck filter, I believe it will have the quick disconect style fittings on it. That will make it more difficullt to integrate into your fuel system.

You might think that since I changed it over the winter that I'd remember, but I'm not sure. I don't think it used quick disconnects. I'll have to double check.

You are correct. Same filter. www.rockauto.com has a all the data. Neat site to reference many parts.

No data, but consider this. That filter has at most a 10 micron paper element. There is no free lunch, and a 10 micron filter that size is going to be a restriction with its low filter area, especially when it gets dirty. Restrictions in the fuel system cause heat build up in the fuel. I have been battling heat saturation in my car and have replaced every "it should be big enough" part with overkill parts.

Thank you. I was concerned about this relatively small surface area, and the flow demands of the bigger engines.

Not to take anything away from the 'vettes, but a 350 making 400 hp and a 454 or larger, making 600 or more hp, is a big, big, difference in fuel demands. Especially when you consider that many built BB engines are not as efficient, so their BSFC goes up, and therefore the fuel demands (volume).

I will say this again. This filter has been used countless times on a big block making 600HP, with no pressure drops at WOT.
