How much presure is put out by the fuel pump on an 84? I am looking for an alternate pump for my car.

 

mOST EFI PUMPS will deliver enough for non racing use. eg my k-jet car (needs 75psi) has a single external pump from a later LH injection car on it, runs fine, deliver pressure and gallons/hr as needed. See if you can find a Bosch list of pumps and replacement numbers on the web....my theory is that (as long as its intended for injection) if it fits in the plumbing, it should do the job. YMMV of course.

You should have pump Bosch 0580 464 045 (current from 83-86 LH) according to Bosch, with no supercession or universal replacement. 928 intl list 580 464 017 for 80-86, which Bosch list as replaced by 580 254 053....

I believe the fuel pump is capable of producing about 8 bar (120psi). An internal relief valve prevents the pump from exceeding this pressure.

 

My 84 runs at about 42 psi. The older CIS systems run around 70ish psi.

 

spare time... Specs say:
'84 L-jetronic & LH-jetronic :
2 bar, engine idle; or, engine off,
2.5 (+/- 0.2) bar, relay socket bridged
(& at least 1,150 cc delivery in 30 sec.).

G'luck.

 

Each injection system has some way of regulating the fuel pressure to spec., but the pump max pressure (with internal relief) is 8 bar.
