Fuel pump question.

I have a very slight leak from the fuel pump, as i'm finding it hard to get a new one, does anyone know if the engine in my hiace shares parts with any other engines?

Mine is a 1993 Hiace 100 series with a 2.8 diesel, chassis number starts with LH12300

Thanks in advance

Check the below link I did a search on your model and 'pump' I see some injection pumps listed.

Hi Funbus!!

Glad to see you and the Hiace are still together.

Where exactly is the pump leaking from? It may just need a new washer or bit of PTFE, or perhaps a seal.

Thanks, yeah we're still together, it's been almost 9 years

As for the leak, not actually sure, i had the MOT yesterday and my guy said that it's not really a leak as such, it's more like it's sweating, so no fuel dripping yet, but he did say that it might be something simple like a seal or gasket, but wont know until he takes it out.

Nine years, wow!

If it's not leaking much I'd leave it alone until you have to have the timing belt done. I say this because to remove it you need to take the timing belt off anyway!

Depending where the leak is it could be quite fixable in-situ. Mine was seeping out around the engine speed output (the big 30mm ring nut on top), I fixed it with a bit of PTFE tape, took about 20 minutes.

Good luck!

Thanks, i'm really hoping it's a simple fix like yours

Had a leak develop on mine last year. Was a constant drip while at idle, was losing 1 mpg each tank and diesel is too expensive. LH100 series 2.4 liter, my pump part number is 22100-5B300, found 22100-5B301 on eBay for about $300 with another $100 shipping from Dubai. They're the same from what I could tell, and functions fine ever since the swap. I couldn't afford the downtime as it's my daily driver, so I paid to have a shop swap it. Plus side, now I have a spare injection pump and can look into rebuilding it at my convenience.
Hope your sweat doesn't turn into a drip!
