Fuel System Upgrade

So, I am currently in the process of getting my Z ready for tuning, so far, I've purchased a PR DIY stage 2.5 (Walbro 535) kit to upgrade the stock LPFP. After the initial tune on pump gas, I will be making the car Flex Fuel capable and setting up port and Meth. injection, which leads me to the question of how to install a second pump without compromising SAFETY due to the unique configuration of the Z's fuel tank with the side mounted access lid/filter assembly. After a bit of searching, I've settled on the https://precisionraceworks.com/prod...&_ss=rPR top hat kit for the A90/Z4 M40i cars, I am hoping that if it doesn't fit exactly, it will lend itself to be easily modified as it is billet aluminum, what are your thoughts? anyone have an E89 filter/lid on hand to take a measurement of the flange outer diameter?
 
I think most members here haven’t wandered as far off piste as you are doing..

I took the uprated stage 1 pump in place of the OE pump.. as most folks here are running 95/98 Ron fuel..there’s no E30/40/50/60/85 here in UK..

I’ve got an upgraded EKP to match it.

In Europe there is E fuels but many countries restrict the level of modification that owners can undertake..

A friend of mine in Italy is doing a bigger upgrade but he’s not yet accessed the fuel tank..

I’ll ask him when he might..
