as things go on, so the small questions come up for all the small details, and who better to call on then the guys who have already done such conversions!!
the vehicle has a low pressure fuel pump, by the tank, from the factory!!
have a choice, of either replacing that pump, with a high pressure EFI pump, and replacing all the pipes accordingly, or using the pipes as they are, and have surge tank and a high pressure fuel pump in front, under the bonnet!!
have on my own decided to go with the surge tank, mainly basses on what I have read!!
so unless someone can show me that this is completely wrong, plan on going this way!!
already have the main piece of tubing for the tank, in stainless steel!!
having issues with webshots, so will post pics of that later!!
as for the fittings just need to get the size of fuel pipes that I will be using and then will deal with those small issues!!
good chance will have custom ones made, there is more then one person with a lathe, that has offered help!!
so far so good!!
so if any one would care to share the pics of their surge tanks, or give some advice, would be great, it would save me having to reinvent the wheel, have seen one on a vehicle, however does not make sense the way its done!!
the one I saw, has the low pressure fuel feed, and return on top of the surge tank
and
the feed for the EFI pump comes from the bottom of the tank, as does the return from the EFI fuel rails!!
now, my limited logic tells me to have the return from the EFI rails also into the top of the tank
could be missing something, as that is also low pressure!!
my experience with this is almost Zero
will need to do a search on this one!!
all advice and info will be highly appreciated!!
Got a certified welder near me that could also give you a "sabs" certificate for that welding....
