howdy. I'm wondering is the in-tank fuel pump on the xr2i e.f.i the same as the mk 4 xr3i fuel pump also e.f.i? My pump is on the way out possibly and the only brand new one i can source is for the xr2i.I replaced it with a second hand unit about a year ago but it's gonna have to come out again by the looks of it. Thankyou
