Good question. It's after the thermostat in the Ea-Ed I6..... Cheers ToranaGuy

just had a look on the mondeo thermostat housing and it has a take off just after the thermostat for the mondeo.

i used middle bolt hole for the PS pump through the AC/PS bracket, cut off the spigot that the ribbed pulley mounts onto on an EF tensioner (nowdays i would have turned one up from scratch - but i didnt have a lathe then) and bolted it to the bracket through the middle hole, (using the tapped hole in the tensioner part that normally holds the pulley to it) it lined the pulley up pretty much perfectly (maybe a bit of filing but i dont remember now) where it needed to go to be inline with the other acessory pullies and the crank pulley and welded it to the bracket permenantly. then i measured what sized belt i needed and bought the one closest to it, mine was a 1470 i think but yours will be different if your keeping AC - i also cut off the unused parts of the bracket as i wasnt keeping AC
You could also get a length of allthread the same size as the threaded hole in the tensioner and put it through like a stud with one nut from the back to hold it to the bracket and one from the front to hold the pulley on. this all sounds long winded but once you get an EF tensioner in your hands you should be able to decifer what im on about - its not the prettiest method but it was simple, you could also set something up that mounted exactly like the PS pump with the same sized pulley so you didnt need a different sized belt, but this would require tools (lathe) or cost $$$ to get made up ALSO if your using a very early engine (HA - HB zetec) i think the bracket i talk about was cast iron/steel so you can weld to it, and if you use a Blacktop engine from a focus / HE mondeo they have a different setup

Sounds good will have to try it at some point.
Mine is a silvertop also. Finally got it finished and fired up today but there is something up with the dam bike carbys when i put the fuel pump on it gets to the pressure it is ment to have set by the regulator and a few sec later fuel starts comming out a little hole on each one i have my pump on a switch and if i start it for a few sec then off for a min and so on i can run it so have to sort this out before i can start using it. got it around the block a few times though goes better than the old Pinto for sure |

too much fuel,too much pressure? there may be some kind of pressure regulator or a valve that belongs in the bike fuel system that you dont have, or there may need to be a return line of some sort
damn i wish mine ran and could be driven ANY distance

Some carbs do require return lines. My mighty boy has a return system sort of like most EFI systems use. It has a special float that if the fuel level get's too high in the carby, it sends fuel back to the tank via the return line. At lower rpms fuel is almost constantly returning to the tank, but at WOT, almost none get's returned....

I have a pressure regulator was set to just under 2psi. was told max 2psi for these carbs. I wound the reg down to 1.3psi and still seems to overflow.
Is there a electric fuel pump that stops pumping when it reaches pressure? I installed a fuel return and it still seems to do it. From what i read the ZX6R that the carbs came from has no fuel pump. It is just gravity fed from the tank. Emailed the company in the UK that I bought the kit from to see what they have to say |

if the carbs want to be gravity fed, how about a "surge tank" sort of arrangement in the engine bay, fed by a lift pump with a return line to the main tank, then just gravity feed from the surge tank to the carbs?
needing a decent size return would be the only issue.

A surge tank that gravity feeds the carbys would work.
Archer15 -> You installed a return line, how big is it? Where is it hooked up? On the carbs or the regulator? Have you tried taking a short piece of hose, plumbing it into a 5lt fuel can sitting in the engine bay & seeing what happens, if the carbs leak or not? Cheers ToranaGuy

1.whatever psi seems like a reasonable amount of pressure (gravity is what acts as a fuel pump in a gravity feed system) as toranaguy says, hook the carbs up to a fuel can hanging over the engine bay and see if they still leak, if not - youve still got too much pressure, if they do youve got a plumbing problem

I will try it out on the weekend. I think it would work fine with gravity feed. it only leaks when it gets up to pressure.
Thank you for your advice. Will let you know how I go |

got a reply from the supplier as below looks like I might have to pull the carbs off
The pressure seems OK, but you can cut it back even more, as long as the engine isn't starved, the lower the better. It sounds more like the float needles or floats might be sticking. Try tapping the bowls gently while the fuel pump is on, or if not, take off the carbs, drain them, turn them upside down, remove the bowls and check inside. In the final event you could connect the plastic tees & run them to a temporary catch tank, but I think once everything is shaken down the overflows will stop. Should i start a new thread. did not intend to hijack JOSE's thread |
