So I just bought my truck about a month ago. Signed up here on the forums and found that the light next to my pyrometer is a fuel pressure light. Well.... It's starting to blink more often. It gets worse as the tank emptys. On a full tank I can keep the light off till about 2000 rpms.

Whats are my options for fixing this?
Is there a fuel filter that I can change?
I know a FASS or an Air Dog will fix it
what about a holley blue/black pump?

what would be the best solution (for the money) to fix this problem. Thanks guys

 

Get yourself a fuel pressure guage as soon as possible. Not doing so may cause you to lose the Injector pump (VP-44) and face a $1k+ repair.

The best fixes are an Airdog, FASS or RASP type pump. Holly blue is an option but they arent designed for diesel - some last for awhile most dont last very long - its a crapshoot and a waste of money, IMO. Holly black - same deal, not designed for diesel and puts out too much pressure if you still pnal on using the OEM style lift pump.

Yes, there is a fuel filter - and you should be changing the filter every second oil change. Heres the procedure for changing it:

Get a fuel pressure gauge... I've also got a low pressure light and mine blinks when I'm on it hard. So at least you would know if you fuel pressure is good. Also my low pressure switch just gave up about 1 month ago and was leaking fuel.

What your seeing is the pulses of the VP44 and it will beat a low pressure switch in a short order too... I'm currently looking to replace mine with a adjustable Hobbs Switch and put it in after the needle valve to keep it from getting beat up...

So if you get a electric gauge you going to need a needle valve as well just to protect the fuel pressure sender from getting beat from the pulses...

 

Definetly get something to protect the sender! I trashed one in about 2 months because I didn't. I used the snubber fitting Autometer sells.

For pumps, Airdog and FASS and Glacier Diesel are good choices. IF your more of a do it yourself kind of guy you can put a system together with a Walbro pump for a little cheaper.

Just for kicks and giggles. If your not going to bomb your truck much an Airtex stock replacement that Carquest sells is pretty good. I've had one on my truck for a year now. The only problem is it doesn't move enough fuel for a bombed truck.

 

I will be bombing it soon. 5" and injectors are soon to come

what about something like these
