is the fuel filter on the z external or inside the gas tank?

 

It's built into the fuel pump and is not user servicable.

 

There's no filter, But there is a mesh screen around the inlet to the fuel pump, and the fuel pump itself has a built in filter that is not replaceable. If the filter gets clogged, you will need a pump replacement.

 

im getting what feels like a lack of fuel, trying to source the problem, any other ideas what could be causing it? injectors? car has about 25k miles and i do track it about 5 times a year

car is base model and no traction control, tends to happen when i pin the throttle while turning. Was at the track yesterday, never happened while on the track but after the event on the way home started happening again, seems to happen only with driving on the street

 

It's not too difficult to get the fuel pump assembly out; I've done it dozens of times....just need some time in the Derail garage if you know what I mean, lol...

It could be your fuel pump too, or dirty injectors....are you leaning out?

 

+1...

 

This is pretty common with Z/G's if you have under a half tank of gas and hard cornering...poor tank design... have you tried on a full tank?

 

maybe its time to upgrade to a walboro, well see if that fixes the problem

tank was at 3/4 full so shouldnt be the gas tank, plus car was at 1/4 beginning of my track session and didnt have any problems.

 

Long rt corners will cause a starve under 1/2 tank, the starting a session at 3/4 is not big deal but a track condition the car gets about 8 MPG , so its actually tearing thru gas pretty quick.

I'm thinking about modding to a dual pump system, one pump on each side. Screw fuel starve issues.

doesn’t that saddle bag arrangement over the shaft already have 2 pumps? Secondary feeds the main with line to the engine. Sounds like maybe you want both pumps directly feeding the heads? Likely extra fuel line & other stuff.
