fuel pump reducer
I have a new fuel pump that has a 15mm inlet, the problem I have is that the tank outlet is 8mm, are there any reducers available?

I think youll struggle to maintain fuel pressure if you reduce the inlet.

thats massive Ive heard of them being 8 or 10 mm but not 15 what has it come off? are you sure that a filter doesn't fit at that point and
reduces to 10mm
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

My pump is 12 mm inlet and my pipework is 10mm
I had an adapter/reducer on mine and I /think/ its the reason my pump went noisy prematurely
(that and the fact it did run dry a few times getting giddy on roundabouts!)
The "neat" solution (and I suspect the right one) is to add a fuel swirl pot with the same sized connector
feeding the swirl pot with the exhisting pipework to maintain a good fuel supply /throughput to the pump
I have since added a swirl pot...which has meant it no longer has issues when getting giddy..but the pump is still noisy :-(
I suspect they are not that great at "sucking" and really require as little resistance as possible on the inlet side (unless I was just
unlucky?)
I do have another pump on standby here for the day the original one ceases to work...but it came through with a 10mm inlet ....DOH!
I have a mate about to go EFI and he ordered one on eBay and his came through with a 15mm inlet and his exhisiting plumbing is for 8mm!

Rob

IIRC the outlet from my fuel tank is 8mm but I use a swirl pot and a primer pump , the outlet from the swirl pot is possibly 15mm as is the inlet to
the high pressure pump. A Vauxhall Cavalier fuel delivery hose fits a treat.

My ex Audi fuel pump has a 15mm inlet. I used a reducer fine.

Where did you buy a reducer or did you have to make one?
