I'd like to avoid external pumps/surge tanks etc if I can. I haven't been paying attention to the world of fuel pumps for the last decade so I don't know what the latest hotness is. Can anyone fill me in?
    The Bosch 540 LPH may get you close to what you want...

      Careful of the KBS and POR15 coatings if the intention is to use E85. A few people on here have had big issues with the coating lifting and blocking pick ups.

        Ah nice, that looks like it might do the trick and doesn't look much larger than the old Walbro unit from what I can tell. It doesn't say anything about E85 compatibility in that link, or is that just assumed these days?

        Thanks for the warning, but as above I don't think I'll need to use any coatings in my tank, at least I hope not! Just needs a real good clean I think.

          Can you get them sandblasted internally/externally and then gal dipped or something?

            If you have a high pressure hose with this sort of head, you can often take the shroud off and wiggle the rest through the hole:


            Works well for getting most of it off.

              Drscrote used the KBS kit on his purple XJ6 fuel tank. It failed the first time but KBS provided a solution when he emailed them

                I don't think Millsi was as lucky with the Hilux.

                  The Bosch website states "Improved E85 tolerance through internal design and materials" which kind of makes it sound like "yeah, it's sorta compatible..."

                  Pretty sure it's the same pump as the DW400, and they state E85 compatibility.

                    if radiator repair shops still exist, you could get them to dunk it in there tanks to clean it out?

                      Thanks, sounds like that one might be the go then.

                      Never thought of that! I'll keep that in mind as a plan B.

                        Meanwhile I'm getting the fuel pump hanger ready to go. That threaded fitting on the outlet line really didn't want to come off, but I got it good and hot with a butane torch then got in there with some big pliers, it fucked up the 14mm hex a bit but got the job done:





                        I'm glad this worked because my alternate plan was to cut off the outlet line and replace it with a -6AN bulkhead fitting, but after investigating fitment with the fuel tank installed it looks like there isn't enough room for a 90 degree elbow without smashing the floorpan with a hammer or similar - the factory outlet tube barely clears the floorpan as it is.

                        Anyway I checked the size of that threaded fitting and it's a M14x1.5 inverted flare which is pretty unusual, but after a bit of searching it turns out Speedflow makes a -6AN adapter for it:

                        https://speedflow.com.au/metric-fema...o-6-male-from/

                        So hopefully that's the fuel tank end of the fuel system sorted out. The next link in the chain is the fuel filter, ideally something with -6AN inlet/outlet and a replaceable filter element. Anyone got suggestions?

                          Feel like I'm spamming a bit, but also looking at this stuff for myself. I'm liking the Turbosmart filters, and want at least 10 micron. From memory Bosch recommends 5 micron.

                          https://www.golebysparts.com.au/coll...r-ts-0402-1130

                          You would want to get that tank pretty clean, and/or place the filter in an easily serviceable location for obvious reasons haha

                            Yeah I was looking at them, seems a bit expensive for a fuel filter but it certainly fits the bill!

                              I've used the Speedflow 10 Micron AN6 ones. They're great, but fucking spendy.

                                I ended up with this:
                                https://www.aeroflowperformance.com/...lter-10-micron

                                Needed -12ORB to -6AN adapters, but they were easy to come by.

                                Available much much much much cheaper on eBay. I think i paid $90 for mine, including the adapters.

                                Best bit is that it fits in a standard 50mm fuel pump holder.
