Fitted my servo take off on the manifold, fitted the vents and jets, got gaskets. Got a fitting for oil breather connection but need to get an uneven tee so i can attach the evap line. Just need to get a fuel tee and some pipe. What size is appropriate for the dells please?
here we go: 32 vents 135 mains 60 idles 180 airs 9164.2 emulsion tubes Start 80s (choke plated) Pumps 35
8 mm I.d from memory , if your type 4 with manual pump you need a 8-6 mm reducer , most peeps run fuel in the right carb and out and into left . Float heights are uber critical .
Will have to have a look at float hights, not entirely sure what Im doing there wil lneed to read up on that!. Currently have a filter after the pump and 8 mm feeding my single weber. Was going to plonk a tee on that as ive got single banjos on both carbs. (do have the original twin banjos)
. Not a good idea to have filter after the pump as it then pressurised . Originally both carbs would have twin banjos
point taken but been fine for the last 18 years. Will look at getting a reducer for it (can you get these?) Yep they are by my maths too. Got some 138s but thats the biggest I have at the moment. 4.5 rule suggests 144
I have some from those IDFs I renewed....I'll dig them out...see what's what...may be interchangeable, maybe not
@lhu1281 I have the original twin banjo. Would i be better off using that on one side and then feeding off to the second carb. (saves me buying a tee but thought it might starve the other carb! What do you think?
Are you running a standard mech fuel pump ? I made a reducer by machining a bit of 10 mm stainless to 8 mm one end and 6 the other . ...... I may have a spare twin banjo . I just tried to keep to minimum number of joints . Edit , that's how they were originally on Alfas . I have no problems with mine with fuel starvation and from memory that's how they say in the su performance book ...
Yes Im using the standard pump. I do have the twin banjo so will use it. I take your point re joints. would it be detrimental to keep it at 6mm up to the first carp and use the unequal twin banjo (the one thats for the return to the tank on the original car!
Not sure on that as from memory the tank return hole is small . I could do you a reducer this week at work
