think i'm coming back to the two again.Is it easier to run a in-line pump rather than dropping the tank which i did last time as it was a pain in the ass

IMHO, if you want a reliable 300+bhp stock motor, then you sure as hell would want to know that you haven't got a thin walled block.Sure, it's not worth rebuilding
"just in case", but it's worth noting in the back of your mind that, someday, the block might crack, and then you'll need to consider some
(costly) options.

I had the walbro pump on my last tubby,but it really whined,got on my nerves!!
