Possible source for Flapper Injectors....

[dwiddows]

Thought I'd drop this in just in case it's useful to anyone.

When looking up the part numbers on my injectors I've found that one one side of the plug molding they have a lucas number and on the other they had a bosch number. Both part numbers seem to be pretty expensive from the usual suppliers.

Digging around on ebay I found a chap selling the bosch part number equivalent 0 280 150 105, remanufactured, in sets of 4, for £20!

Now this seemed too good to be true but I thought I'd risk buying them anyway. Quotes to just get mine cleaned have been a lot more than that.

Turns out, they do seem to come from the tuning company mentioned in his listing . . and they look like they are good quality items. (to my untrained eye)

Until I get my engine rebuilt and back up and running I can't vouch for their quality but I thought it's worthing passing the info on in case someone else is in need of some spares and wants to give the guy a try.

Search for "Bosch Fuel Injector X4 - 0280150105" on ebay if you are interested.

Cheers,
Darren

Not a bad pricew per se, but... you do have to be failry unlucky to have injectors so bad that they need replacing. Usually the inlet filters can be cleaned, you can lash-up a flow test yourself and there are so many spare injection bits on Ebay that I've bought entire injection systems for £20 before now, from the inlet manifold upwards.
For a quick fix, admittedly, you can't fall off at that price.
Though I'll let someomne else try them first and report back...

I was just about to refurb my 350i's 105s; so I'll be the guinea pig... although I'm changing the cam and various other bits at the same time.

Indeed, the injectors are pretty lifetime bulletproof, with only the filter basket, pintle cap and the connection hose liable to need replacement.

This shortform program explains how the typical RV8 injectors can be serviced.

• Cut off the swaged hose collar at a sharp angle using suitable snips or a small metal saw.

• Discard the old collar and fuel hose.

• Extract the filter with a small "easy-out" or a woodscrew.

• Cut off the pintle caps with a stout blade.

• Wash everything with Panel Wipe.

• Blow-dry and clean with an airline.

• Press new caps and filters in place in a vice using hardwood protectors with a small hole preventing pintle damage.

• Test each injector on a hose containing an ounce or two of Panel Wipe (or another relatively benign simulator for petrol) under 30 lbs pressure from an airline.

• Pulse the coil with a 3 volt (not 12 volt) power supply and observe against a back-light, an orderly conical spray pattern with no dribbling.



• Couple new hose lengths to the injectors using neat fuel hose clips from Burlen/S.U.

• Upon re-assembly connect the new injector hoses to the fuel rail along with any other new hoses as required using the same type clips.



All the components needed for injector overhaul can be sourced from a local injection specialist or from Burlen/S.U. Fuel Systems (Tel: [phone]) http://www.sucarb.co.uk/default.aspx under the following Burlen/S.U. part numbers and description (2012 prices).

• BHC1214 Hose Clamps 12-14mm 100 off £28.00
• Packing and Post £3.95 all prices + vat

I still think it's a good deal if they really are new old stock injectors (and they say they have 500!). Assuming they're not stuck it should be a lot less hassle than doing the refurb myself, and cheaper than sending off for a refurb.

Plus when my refurbed SEAC injectors were sent back one of them was stuck too... took an enthusiastic 'tap' with a sharp (hammer shaped) impliment to fix. I'll be ready with the same impliment!

I've got the car running on the new injectors now, and can report no issues. They certainly looked new, although curiously had some overspray on the electrical connectors. I had to buy new seals (the ones I had refurbed came fitted with new seals), but the hoses were correct and attached with what looks like OE swaged collars.

I initially tested them by whipping open the throttle plate and listening to them fire as the throttle position sensor picked up rapid movement. The new injectors all fired together in one 'click'; the old injectors all seemed to react at different speed and gave a kind of rattling sound as they tried to fire on the tps signal. Seemed like a decent way for checking for sticky injectors.
