Its not a really bad job.. but not a good job either imo ...... main problem is if you cant get the hard pipe undone on top of pump.....many many people cant including me ( Andyuk75 got his undone though lucky man) ... if you cant get it undone which is more than likely ( be careful as it bends easy and is very very tight ) then you need to undo the flexi pipe where it meets the hard pipes on car underside, and then mod seat base ( cut it slightly ) to give access to get pump and big flexi piping out....other than that piece of pish
I have a walbro fitted to my 3 but in conjunction with a sard fuel regulator. I must admit that i think the walbro 190L is way too powerfull for a standerd ish early evo engine. With out the sard my fuel was running sooo rich to the point it was running off the scale (below 10.5) on the dyno graph. Fitted the sard and had to back the standered fuel pressure off by 5 psi for it to give a decent reading. The engine is still over fueling but not by much and if i take it back another 2 psi i can now get 310 bhp as apposed to 240 bhp with std fuel pressure. But to be on the safe side i run it slightly rich anyway.
Paul, if you want to know an easy way of fitting the pump then pm me and can give you the option.
