I am sorting my fuel system out at the moment and i can go one of two routes, the first is to fit an External Pump (somthing like a Aeromotive) but to do this i must weld a sump into my stock tank. The second option is to fit twin in tank pumps, i have heard of this done but have never seen it.
Is there a write up or has any one on hear dont the twin pump mod on there Rx7? i just want to know how easy it is to do and what pumps are the best to do it with?
Thanks.........Chris

it would equal more than a 255 lph walboro.
Either way, the aeroquip fuel pressure regulator has 2 inlets. I am going to run 1 pump to the primary, 1 pump to the secondary(RAILS) and then use the aeroquip FPR as the "Y". They'll go back to the pump via the charcoal canister hard line(or you can run 3 meters of -6 hose) and then I'll tap the fuel pump assembly with a bulkhead fitting for the return IN...

I am just checking out all options, How would you wire it all up? if i used the stock wiring and just split it would'nt that drop the Voltage going to each pump? and if i Relayed it then it would get 12v all the time? would this cause any problems?
I like the Idear of having two completely split fuel systems, it would'nt be that hard to do but why would it be better to do it this way and not just link the two and keep the single feed?
The best bit is i have two Welbro 255 pumps doing nothing and this would make a quite good in tank set up but i want to make sure there is'nt going to be a problem with the power feed. Doing it this way i can keep the Parrel set up i have just fitted too.
