Well are you ready for the story?

I took this second pump back this arvo, now both pumps looked like they had been bolted up.

Fuel miser had 2 pump listings but one of the numbers was a goss pump.
Stay with me.......
When we looked in the photo book the 1st pump (goss) looked different to what was in the box, so the salesman looked it up and this box had been with them for 10 years and had been returned many times.

So we guessed it must be the wrong pump in the box and he has ordered a new one.
So heres hoping the one that will arrive monday is correct.

Find another supplier. There is only one style of A14.

The easy way to remember which pump fits which, the Long arm pumps suits the last revision of the A-series block [dizzy in the middle] and the short arm pump suits the early blocks [dizzy up front] this includes the A10 to my understanding.

So i took the old one back and got this one, it also feels like it doesnt make contact with the cam.
What the duce? Those are the only listings the guy said he has.

Had a go at fitting this today, it makes no contact with the cam, even with the spacer thing removed.
Looks like im back to auto one.

Now wheres that receipt.

well if you put a short arm in your motor you just wont get fuel cause it wont reach the cam

wont cause damage at all.... cause it wont run... but also cause it wont touch

i second that the mech pump if fine for twins, ran mech pump on rally car for last 3yrs

Yeah, plenty.

I ran my sets of twin 45 webers, 40 webers, 40 PHH Mikuni's on stock pump, no issues whatsoever.

Some people have argued that you do need the higher pressure electric pump etc etc to supply these twin barrel carbs but they have never proved this and I have never faulted the factory pump on fuel delivery insufficiency.

Oh jeeze this could be a worry.
Hey Chris will this pump flow enough for my new dellortos??

I can't remember the details but make sure you do get the right one. I also ran a long arm one and it wiped a gouge into the eccentric fuel pump lobe on the camshaft. Also be sure you fit the phenolic spacer back in place as this also influences the placement of the fuel pump arm against the cam ecc. lobe.

The pump I used was off an A14 or A15 and I put it into my A12. It looked similar to that one with the sealed top but it had a different looking arm again, more like the long one in the image shown by 1200rallycar.

i will have a go at fitting it tomorow, just didnt want to fit it and be wrong and try to do the whole return a oily pump for a refund thing.
