Hi, I've a problem with the fuel pressure under load as it's only rising up to aprox 55 Psi, I've noticed the pressure was low on idle (30 Psi) so I raised the pressure up to what it should be on idle and did I little test drive but the pressure does not come above 55 Psi.
The pump is a Bosch 044 and about 3 years old but sounds "crispy", could it be the pump or the regulator which is a Aeromotive A1000.
What's best to test and how before spending money on new parts?

 

100% it will be fuel regulator mate

Had issues with mine on Dyno and I know Mr Shead @ MA Developments uses them purely as a door stop

I have a spare I can take to Ford Fair I'd you are coming over.

 

take it apart and you will find the spring broken at a guess
i bought a high powered car from somebody who had a new aero fpr fail[spring]-they sent him two springs....must be confident of their product[not]

 

And they don't like seating properly inside leading to low pressure and inability to increase correctly with rising boost.

 

Thanks guys, will open it tomorrow

Not coming to Ford Fair Rich but going to Time Attack the week after at Cadwell Park

 

Opened up the FPR, i think i need no words

 

are you goin to repar or bin it?
i may have a spring somewhere-will have a look if you are-and send dimensions of spring size-well size it should be....

crap item eh?

 

If i could get a cheap repair like a new spring i will repair it for the time being

 

Any friends over to Ford Fair??

 

wow mate that is well and truly beyond help lol

 

Yes mate, i had contact with Aeromotive and showed them these pics, they asked me if i was in marine or automotive
