Help plumbing my fuel pump EFI

I have a Bosch pump with a 15mm inlet and a 8mm outlet. The 8mm is no problem. It is getting fuel to the pump that is the problem. What I need to do is get fuel from a tank with a 9mm outlet via a low pressure filter to the pump with a 15 mm inlet.

I can find 15mm pipe etc. However I can't find a filter with the right ends or any reducers which will fit. The pump inlet has an olive type bump on the end so I could use a 16mm pipe here as the seal would still be good(??). But again no suitable reducers etc seem to be on the market.

Somebody else must be using a pump with a similiarly large inlet so any photos / suggections would be most welcome. I have gone cross eyed starring at the screen trying to search for a solution!!

Thanks for any help.

Luckily standard plumbing sizes are 10mm and 15mm, go to Thompsons and ask for a 10-15mm reducer. this is what I did, I am running standardish 2.0 Pinto injection





If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Try Googling Pirtek, they have online catalogues and you could use a combination if they don't have one that suite. I would definitely say go for the exact right size i.e. don't try a 16mm bore pipe on a 15 fitting, its enough effort stopping leaks on pipes that do match!

Nice idea. Would the standard plumbing ones be suitable for fuel (albeit at low pressure prior to the pump)? Surely there must be a motorsport solution though? Anyone?


[don't try a 16mm bore pipe on a 15 fitting, its enough effort stopping leaks on pipes that do match!]

I thought as much. It just seemed there was a greater selection of 16mm fittings.

My car passed its 7th MOT recently, no problems

Are you sure its a 15mm inlet and not 12mm? The "olived" section may be approaching 15mm, but thats not the nominal size.





Long live RWD...

Hi Joe,

The pump has a large inlet for a reason, you should NOT reduce it, keep the 1/2" inlet to the pump right to the tank (modify your tank to have a large outlet). Most Bosch pumps are designed not to require an inlet filter (filter inside pump housing) you will need a filter on the outlet of the pump - i use jag V12 filters as they are high flow and will withstand high pressure.

What are you building?
