My stock pump is dead (good cause my car is turbo converted) So I ordered a 1:1 rising rate FPR and a walbro 255lph hp fuel pump, I got the walbro but the fpr will take about a week. Can I install a Walbro and keep stock kouki rails and FPR in the meantime? I got someone to do the welding and everything I just need to use the car.

 

I drove mine with the Walboro and the stock FPR for months.

 

OK
