Afyer wafting around a few offroad forums i've decided i want some onboard air for my truck Being a clueless plum i don't have the savvy/time or knoweledge to do it Anyone got a clue how to do this to a 95 hilux surf? Or do the job for me in return for a 6 pack and plenty of bacon sarnies  Tht idea also came from instructables ( search onboard air to see what i mean) |

You need an aircon pump with built in oil reservoir. Most in Uk are the type which use the air con fluid as a lubricant so not suitable.
Research further and you will find which cars are donors for the suitable type.

i've been looking and they reckon a sanden would be ok as i cant find any york compressors for my budget
i know sandens were used on pug 307's
what about using an air/oil seperator with a return feed back to the compressor sump?

Paul's suggestion may be a good one, depending on your needs.
I had a Discovery II one (same thing) on my landy mounted out of the way with a pcl coupler just inside the cab to hook up an airline.
It worked fine for topping up tyre pressures, but the output wasn't great. I was running 35 14.5 15s with beadlocks, which always lost pressure over a week or so, so it was worth its weight in gold.
It just took ages to pump the beggars back up after I'd pressured them right down to 3psi!
If you're looking for high output and hoping to run some other airtools, I'd be looking at the Volvo pumps already mentioned. I take it you've checked out difflock.com for advice!

I'm looking for a higher output than the disco pump as i want to be able to pump up my tyres, carry an impact wrench run a set of train horns and maybe a nail gun for helping my mate with a few projects
I'm doubtfull that an american rv2 pump would fit ( either ford truck or a dodge ) But any pump with its own sump will work at a push
As for reliability I'm taking a stab in the dark as
Ypu guys seem to know a lot more than me about this. What older volvo pumps would be suitable?
Unrelated note..... Ill be building an onboard arc welder at some point if i can get the right alternator ( bloody usefull on the lanes when a mate breaks something)

A nail gun and impact wrench use a massive amount of air volume so you should be looking at a PTO operated proper compressor as a air con compressor won't supply anywhere near enough. It's not pressure you need but volume. Sorry but you are going to be very dissapointed with an air con compressor.
Think about it - garage compressors (excluding the motor) are huge things compared to an air con item. Even a mid sized compressor from Machine Mart etc will struggle with air tools yet you are considering something tiny will produce more volume ! OK you can have a reservoir but that will just give enough volume to maybe fire a couple of nails or undo one nut with wrench.
Maybe a portable petrol powered compressor in the back might be a better idea ?

Not realy feasable with the ammount of stuff in my truck
I usually have the twin buggy, swmbo's nippers bike and all the other family crud
The idea was for an underslung tank upto 150 psi. Should be enough to undo a couple of wheel nuts and pump a few tyres.
I hqve heRd these things cqn get up to around 170psi with no issues. And the 12 v ciggie lighter pumps just mely with my. 35 inch tyres

And the 12 v ciggie lighter pumps just mely with my. 35 inch tyres PSI is pressure. You need volume to work airtools. Even a cheap little electric tyre pump will manage 150-200psi yet wouldn't do anything other than blow up tyres. A static compressor will maybe have a piston displacement of, say, 200cc. This is volume. A air con compressor might have a displacement of only 20cc yet both will produce the same PSI but only the larger displacement will power air tools. Paul H |

Tank size i was looking at would be between 2.5
To 5 gallon so it should be enough size wise to power a nutgun just
To crack a few wheel nuts or pump up a tyre with no issues

I've got a 12v impact wrench. Far easier than an air setup Paul H |

Well ive just had a call and theres a 4 gallon hgv trailer air tank waiting for me and after a measure up it will fit between my chassis rails , now i just need to find the right type of compressor ( I'm still swaying towards a volvo unit) then i'll be getting a few mates over to get the job done |

Change of plan time !!!!!!!
After much soul ( web) searching, i can use the aircon already in my surf
So no need for an extra pump
This could happen a lot sooner than i thought

Aircon compressors are powered though an electric clutch so easy to add a pressure switch to keep the tank topped up. Paul H |

personly I wouldn't use an LR pump, they aint exactly well known for thier long lives and for any air tool you will need (as already stated) volume not pressure, personly I would do as I did, find an ambulance breaker and grab the air pump, air manifold, tank and relays, cheap and works really well. I was surpissed how small the pump was, about the size of a large 12V pump you get from halfords but it would run for ages without seizing unlike most tyre pumps which will only run for 5 or mins at a time before the pistons seize  You could save more money and use a dive tank ort even a butane/propane bottle as the tank ? but with this you'll need to add another valve for in or out  for the ultimate you want an ex water board or transco van with a propper fookoff compressor underneath  |

I was thinking of using a ex army landy 101 ambulance air pump for the resperator kit but the size puts me off
After trawling the hilux surf forums it turns out i can use the stock pump witha few mild mods i can do myself

Paul H Sorry to disagree but a decent nail gun doesn't need a big compressor, we've a framing nailer at work that runs from its own small compressor- its about the size of a suitcase generator with a tank size of about 1 gallon(ish) |
