that would be a good idea. pretty much any fuel filter is going to be a good idea. Is there a section of about 6 inches of rubber line? That would probably be the easiest place to squeeze one in, that way you don't have to cut the fuel lines.

I'm pretty sure I have an extra egr around here, so I will swap that out as well for good measure, after testing the fuel pressure.
they use them because it is the cheapest way to get the increased fuel they need for boost. The guys making real power step up to "real" fuel pumps. The turbo 300zx fuel pump will support 700 whp without breaking a sweat. It has to do with volume pumped at a certain pressure. Walboros, while they do pump 255 lph, it is at something like 50 psi, so at 40 psi, it is pumping more like 200 lph. The stock turbo 300zx fuel pump will move 255 lph at 30 psi. I forget the exact numbers, i'd have to dig the graphs I have out. Think of it like a dyno sheet. The walboro has a really steep, and really peaky power curve, Where as the 300zx TT fuel pump makes the same power throughout the rpm range.
the better pumps, like the 300zx pump aren't more popular because they can cost $300 bucks. Whereas a walboro costs under 100 bucks.
good idea to test the fuel pressure first.
good luck
