i have issues

if yours has a FPR, I believe its supposed to be 52 at idle and 58 with the vacuum line removed. Otherwise its 58 psi, if I remember correctly.

52-55 idling and 58-60 with the vacuum off...i think thats what i remember

55-62 psi with the pump running and engine off. Should go up 3-10 with the vacuum line removed and engine running.

Alan--you still having these problems?

well yesterday we were working on the fuel pump on an airplane and were using a FP gauge.... took a look and it was the same size fitting as on the fuel rail

so after work tossed it on the truck and it idled right at 50psi.... went driving around and at WOT from 1000-2500 it was right at 55 and then as the rpm's came up the pressure dropped to 40, then to 30 then down to 20psi and at 20psi is where the truck started acting up and giving the symptoms that i described....

welp guess its time for a walboro 255 now

Good girl! Yup, FP is dying a slow death. Your FP replacement should be pretty easy--isn't your FP along the driver's side frame rail?

hahaha i wish it was that easy... its an in tank pump.. so im gonna pick one up from Nelson's on either thurs evening when i get in town or if thats too late friday morning... im bringin tools with me so i should be able to swap it out in my buddy's parking lot

if i get it changed i guess ill finally get some 1/4 times in patches.... dang now i gotta fill the bottle

So Alan...the FP was the culprit, huh? Run a lot better now that it is actually getting gas?

i dont know if it was slowly dieing out or if i just dont remember what it feels like going WOT again....

either way it feels alot better, starts alot quicker, and i dont have to pull over fo 20 minutes at a time when traveling long distances :laugh:

so now its time to toss the bottle on it and see if i can blow it up
