whats the deal???

[KTA]

A Fleetguard FS1221 filter costs me $9.21 at my local John Deere dealer.

all right i installed the new fuel filter but its still doing it. what should i check next? this is my daily driver, 70 mi a day, sure would like to get it figured out.

[KTA]

Check your fuel pressure, and if your shure you dont have a linkage problem I am afraid it sounds like your injection pump is on its way out. I see you have some kind of weird governor spring, perhpas that might be related to your problem.

dont want that to be the case. ive got a 4200 gs in there but its always ran fine with it just a little more than needed. thanks for your input ill put a gauge on it and see whats up.
if the lift pump isnt putting out enough to feed the pump would i get this kind of symptom?

[Greenleaf]

I'm not sure. I have never ran one with little/low supply. Check that pressure. Could also check the vacuum (restriction) with a vac. gauge plumbed in.
Once you establish everything outside the pump is go, I'd make lemon aid out of the backet of lemons life has delt you and pull the pump down. Inspect everything and replace the internal springs. Reseal it and install the thing or take it to a shop for a trial run on the stand. That is about 100.00 to *test* the operation.

Bgilbert- Cummins MidSouth wanted $12 3 years ago for a FS1232. I found a Baldwin dealer and got some ordered for $7.xx each. MUCH better than CRAPPA. G/F's boss dont think much of Baldwin (says he had some problems a while, back- he could be getting his colors mixed up, too, though) but he also dont know much about mechanical diesels.

bucket of lemons?? WTF?
what kind of pressure should i be getting where the fuel line goes into the pump? i put a 100psi gauge on the banjo fitting and it fluxuated between 40-60pounds(gauge wasnt liquid filled)which seems high to me.

DP, Cummins, Fleetguard distributor, Scheid Diesel, fs1232 can be had for $9ish. Find a Baldwin distributor and get it about $8ish. Wipe your Chris Hughes with Napa Wix filters:eek:.

TEN FOUR!!!! Find a BALDWIN DIST OR BETTER FIND A REPAIR SHOP THAT GETS A DEAL ON THEM. I pay 24 for a BHAF 2.50 or 3.00 for oil filter and i think 6 or so for fuel filter. I'll look for my last recipt

You have 40 to 60 psi of lift pump pressure?

You need a 20 psi gauge. It should read something like 5 to 7 psi. at idle speed and generally remain there through WOT with the transmission in "N"

If you use a gauge that is nine times higher than your reading, your reading is going to be 80/90% off. I use an Autometer 16 psi mechanical gauge to test the pump and use a Westach 16 psi electric gauge for a permanent install.

Sounds like your gauge is busted or you have an electric lift pump installed designed for a Pratt & Whitney R2800 18 cyl radial engine.

You are checking the wrong fitting, the fuel inlet to the pump is the screwed in line in the front. 6psi is the minimum you should see at any time for proper function.

Check your custom ground fuel pin. If you don't have a washer at the top of the fuel pin it could hang up when the "eccentric" moves down. There might also be a rough spot that is causing the pin to hang up. BTW eccentric is the correct name for what we call the fuel pin.

yep wrong line oops my bad. what should i have at the one i tapped? i ordered a gauge the other day day and it hasnt showed up, so used a fuel pressure gauge off my fuel inj. tester.
Bob ill check that today thanks for the input, you to greenpeaece im mean greenweed or is it greenleaf (just giving you sh!t) i appreciate your help, even though you a smart arss.

[Greenleaf]

I hope it works out and the pump won't have to come down.

You ought to meet him in person! The computer brings out the inner guy! He's quite mellow one on one.

all in fun, Greenleaf has been very helpful and patient with my stupidity and learning endeovers, i also havent met or talked to a 1st gen owner that i didnt like.

ordered up a kit for the pump before greenleaf mentioned springs. what do the springs do? guess ill find out when i tear it down. got a guy here locally that swank recomended when its done ill have him set it up for me.
thanks again for your help guys.

one more Dumb question, i have a ve pump on an 89 industrial 5.9 which doesnt have the afc diaphram on the top cover of the pump, how different is the pump from from ours and can this be used temporareley while im repairing mine? can i swap my top cover with the industrial pump?
