FPR question
Turbo Mini Forums

After buying all the braided hose and fittings that i needed, i'm going to get my car properly plumbed in (also after the demise of my pump!)

Anyone used a FPR like this?

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...:MEWA:IT&ih=002

Will it go down low enough for a carb? The plan is get one that can do carb and injection to save changing at a later date.

I'm also scouting for a Walbro external pump so i can use my JIC fittings again rather than piss about with push on hoses and jubilee clips all the time.

I've sourced a pre-filter:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...:MEWA:IT&ih=006

that should stop the shite getting in as i'm unsure as to whether thats what seized the other pump (although there was no evidence of foam etc from my tank)

I'm using -6 which i've worked out to be more than enough for my needs. Only reason i'm doing it is that all the parts were half the price from the US. I got about 20+ hose ends, 1/4npt to -6AN adaptors plus 10m of hose for less than £200 from Summit

Hi,
If I'd spent £200 on pipes, I'd spend more than £20 on a reg!
I wouldn't trust it, if it screws up when your booting it, it could cost you an engine....

Don't you need a rising rate regulator for a turbo?

Its got a boost reference port so should rise with boost.

Bat, i see what your saying but when i bought all the pipework i had plenty of money

Also we "all" use the metty ones which are of the same caliber.

I may just drill and tap my metty one to be honest to put the fittings in for now.

I keep looking at the fuelab pumps and regulators though...

Iain let me no if you sort anything il keep an eye on the thread.

Got braided hose on mine ,hopfully a neater, safer , easyer soloution, .

I havent managed to sort the reg tho think its got to be a rising rate reg from what ive serched + rob has just said. and only thing ive found is the standard one.

If we sort this the only other prob is into carb witch will have to be push on ?.

This is mine. Soz just an excuise to show a pic

Hi,
I'd stick with the Metro one, at least you know it's a good quality one :)
That's the problem with money, it comes and goes :(

TBH, -6 on the supply side of an efi pump especilly with a filter on it, is NOT big hose by any means.
I personally would have used as big a hose as possible right to the pump, more likely -8 minimum.
You'll soon hear if the pump doesnt like it though.


I would not use an efi regualator on a carb install. Buy one with a proper range of say 0-20psi static. Although you might get away with taking an efi one apart, and fitting a suitable softer spring inside.
A reg with a 0-120psi range, is going to have crap resolution in the 0-5psi range you want for starting off with.
And with a carb, and weedy needle valve, you need accuracy here.

As for feed from pump to carb/reg, in an efi setup at say 50-60psi, -6 will happily feed 1000bhp.

I only ever ran a single 8mm feed/return when I had my twin turbo Rover V8 on a Holley. In-tank Bosch efi pump ( same as in-line ) and typical Malpassi reg, same as metro, and never had any problems.

The GSS392 is the in-line Walbro. Although I doubt you'd need the 255lph version. Not sure if the lesser version is actually any cheaper though. Not honestly sure what fittings these come with. I thought they had push on at the entry ?

I've found this pump, which i've been told is good for 400bhp so it should do the trick for now and for future mods!

Half tempted to get 2 after having my problems and then be able to switch over to the spare

Hi,
I'd welcome someones expert opinion here, but I've been wondering recently while looking for a pump myself, if it possible to have too much flow from a pump?
In your case will the Metro reg cope with 190 LPH as it will need to dump most of it back to the tank.

Gavin :)

It has been seen to stretch the diapraghm over time. but they are pennies.
I reckon it will be ok. the trick is if you can get the outlet pressure down to nothing with the engine not started then there can be no extra pressure on the diapraghm.
There is also the possibility of reducing the current to the pump if you find all the capacity is not needed.

Hi,
That's good point about the current.
I've noticed some of the Vauxhalls had an adjustable regulator between the pump an the filter, so thats another option. :)
Cheers,
Gavin :)

iain, have you killed the Sheepspeed fuel Pump?

Team Racing

I don't reckon that filter is big enough for a 'pre-filter' unless of course you feed the fuel return back into the inlet line...
Of course, it might be just fine!

I got one of these from the States after I had tried two Malpassi FPR's that didn't solve a fuelling problem.

Problem solved after fitment and is a top quality piece of kit compared to the Malpassi item.
Just to add I think the standard Bosch pump is more than up to the job for our needs. I got one of these recently to keep as a spare. A good price for a genuine item unlike those shitty Chinese blue pumps that are being punted on Ebay. Just my 2p worth.

yup, sorry jimbo the lucky yellow tie wrap didnt work!

Dave, it is 4" long by 3" diameter? i thought that would be enough?

To be fair the same seller was selling other filters that werent classed as "pre-pump" so went for this one that was specifically labelled as such.

Got a few months to gather the bits yet for it though.

I'm using one of those regs in the first post on my EFI. I doubt that it will control at 5psi.

A regulator consists of a spring, diaphragm and adjusting screw. Not a lot to go wrong and it should not cost the earth.

I would not dismiss these purely on price.

My thoughts Paul. I was purely asking along the lines of how fine the control is at the bottom end, by the sounds of things, not fine enough

Stevie,

I'm using all braided with JIC threaded fittings as thats what i've got. I know they are a PITA to make, but once made they are durable.

Not to make.. Superstock can be a pain too.

I just hate braided stuff. Too bling. They will rub through anything they touch, and are over priced IMO.

Earls do a nice black cloth braided hose now, and black fittings. If I hadnt spent so much on fittings already, Id be using it !!!

I found that the black stuff wasnt that great to be honest.

I know what you mean about over priced but as i was in the states, it really worked out cheaper than anything to be honest!

Mines not going to be on show, i just want it to last as i dont want to be doing bits all the time

Rick, what fuel pump is that? i'm looking for one with screw in fittings each end

The black fittings are pricy too!

There's nothing wrong with Malpassi. The turbo regs used to be fitted with quite a stiff red diaphragm which as many users on this forum will testify over the years did perish and leak under boost causing the mixture to go lean. When these diaphagms were new they were excellent at controlling the low fuel pressures that the SU carburettor needs. In more recent times Malpassi stopped using the red "stiff" diaphragm and replaced it with a more flexible black rubber type. With my set up this this later type diaphragm caused hysterisis within the fuel system whereas the earlier type had been fine apart from the leakage due to age. Hence I was recommended the aeromotive reg by a guy at FSE who sell Malpassi, go figure??

Im using the Weber Alpha FPR but its not much use for a carb setup!

Why can't you just plumb it all in with your existing FPR and get a new metty pump then just swap them parts when you go EFI? The metty pumps are more expensive than some decent injection pumps so you could make most of your money back selling your metty pump, when you've finished with it...just a thought?
