Fuel reg thread type

[ruishy1]

Can anyone tell me what threads are on the main, and secondary fuel regs where they screw into the rail ?

need to get some banjo fittings to relocate them, once ive done that, its just weld the inlet and get an idler pulley and my supercharger conversion is done

All the fuel regs (primary/secondary) are 1.25 thread pitch. The fuel rail end caps are 1.5 pitch.

thanks very much mate
you have jusyt brought me within a few minor mods of having an SC400 with an M112

No problem, glad to help. Please post a couple pics when you get her running! I am especially curious to see the hood clearances.

 

[ruishy1]

ther wont be any clearance issues, its a homebrew system like superrunners, its sticking out by about 5 inches !

Err, what main and secondary regs?

There is only one reg (the one with a vacuum line on it)
The other one (on the inlet line) is a pulsation dampener.

wel now i know the thread types anyway, im not a mechanic, im an aeronautical engineer when i work on cars i learn as i go

Just pointing it out so you don't go and buy 2 FPR's thinking you need to replace both.

 

[ruishy1]

it wasnt to buy FPR's, im simply relocating them using banjo fittings and female barbed fittings. thats why i needed to know the thread type before i order them

 

[Peewee]

Ah fair enough.

I'm not sure if the FPR can be replaced with a banjo though, as it uses an o-ring to seal it.
I've never looking into it though.

 

[ruishy1]

ive got the banjo fitting, and ive simply used a small die grinder to groove the banjo fitting to fit he o ring
im getting very excited to get it finished, need to get more gas for my tig welder to finish the inlet and an idler pulley, and some holes for my newly acquired snow performance water injection system and it should be ready to fire up !!

 

[hungryforinfo]

Why not just plug the holes, and drill and tap on the sides?

Or put a 90deg elbow fitting on and mount it straight to that.

 

[ruishy1]

it ok, got it all sorted. now its just welding the inlet and its time to fire it up.
knowing my luck it will all go bang !
