Does anyone know what make of fuel pump was fitted to the non-turbo 1.7 diesels? Handbook states it is indirect injection using a rotary pump, but I want to know whether it is a Bosch or Lucas/CAV?

I've looked through the Porter Tipo manual, but doesn't seem to be anything of use in there.

I know that this engine is similar to/the same as those used in the Fiorino and the Uno, but having scoured the web, I still haven't found any confirmation of the pump. My car is a 1994 M, and all I can really do to describe the pump is that the throttle and choke are both mounted on the top of the pump. It's not easy to see the 'front' of the pump to see any sort of make/model on it.

The reason I want to know is that I have read a lot recently about using various forms of vegetable oil in diesels, and I know that an older indirect injection lump like the 1.7D would be ok. Found that a few people are running Uno's and Fiorino's on a mix of diesel and veggy oil, and I'm looking to do the same, probably running a 50:50 mix during the summer and then adjusting down to 70:30 (in diesel's favour) during winter.

My problem is identifying the make of pump - common theory regardless of car make is that the Lucas ones don't like veggy oil , and that serious damage can result.

Can anyone offer any more info on pump make, how to identify the pump make, and what the results were if you have done this.

Thanks in advance....
 
If you check the threads around about 3 to 4 weeks ago in one tipo thread Pottleflump had provided a link to Eper the Fiat parts database. The drawings of the alternate fuel systems are very good in there and you can identify which pump it is from that. Alternatively post a picture and I'll tell you if it is/is not the same as mine in which case its probably the other type..

Hi there,
The pump in question is a Bosch and its fine to run Veggie oil on,
I previously had a Uno 1.7d for a while and always ran it on Rapeseed from Tesco, The mix ratio i used was generally 50:50, Did at one stage get it to 75% veggie but the cold starting was a bit of a problem.
So in general for reliability like you say and what i did was 50:50, You can actually use that all year round as it does not really gain any thickness in consistancy ......

In the uno i did a round trip from norfolk to bristol and back on 1/2 a tank..... Try and beat that....

Very eco friendly too, carbons and hydros minimal, Just watch for the kids chasing you thinking its a chip van....


If you do use it ,you may have to cold heat twice on a morning...





Some people will have a go about Taxation, Customs and Excise ect, Just to stop these people saying its against the law to run your car on veggie its NOT....
I found out the rules changed on 01 July 2007. They used to be cumbersome and require that small producers (home users are just very small producers) register and submit monthly returns.
Now, if you use less than 2500 litres of oil a year, you don't have to register or pay duty!

Hope this helps a little..(y)

Thanks for your replies so far.

I've tried using EPER before, but could never find one that was working. However, have found a link to one within Fiat Forum at

https://www.fiatforum.com/stilo/105937-eper.html?p=1123711

Selected my vehicle model and entered the last 8 digits of the VIN, and it has confirmed my suspicions that I do have the Bosch AC14 pump fitted on my car.

Will see if i can confirm this by having a better look at the pump in the morning, but it looks like I will be stocking up on veggie oil tomorrow!!!

The recent decision by HM Customs was one of the reasons i decided to investigate this.

One more question - is it better for me to phase in the veggie oil in stages, say 10% this week, 20% next week until i hit the desired 50/50, or I can jump straight to the 50/50 mix? If it's any help, my daily roundtrip to work is about 60 miles, and 85% of that dual carriageway and motorway....
 
I think by what you are saying and have described IT IS a Bosch pump,
The other pumps struggle with veggie oil and can actually damage the seals in some cases (only in very long term use),
A 50:50 mix you can run straight away with no problems,

When i started on 50:50 then i gradually increased the oil mix over a period of time, Thats how i got to a 75:25 mix,

To be quite honest and safe i would stay on a 50:50 mix......

We also ran a Vauxhall Astra 1.7 td with no problems...
When you first run it on veggie you will find the car is actually a lot quieter..

Also if you did'nt know the diesel engine was actually designed to run on Peanut oil in the very late 1800's, so peanut farmers could use it as a fuel...
(a bit of useless info for you there)
