If your runnin the stock pump still they will hold pressure intermittently when they are just going bad, you just can't count on em to keep that pressure. So ya it's common to have that happen until one day it will just die for good.

Just curious though as to where your pressure guage is, can you see it the whole time your driving. If not then you need to make it so you can. I have had pumps hold 20 psi while I was sittin in one spot but take it on the road and hit the go pedal and they go right to 0.

 

its on the pillar just below my boost gauge I'll probably put my Glacier diesel order in next week or so

 

I just got my Airdog hooked up, I really like it.. nice and quiet. Go for the Airdog!

 

The original diesel belt drive is the RASP by DTT. But all the pumps have the same issue, they wear in the front bushing causing leaks eventually. This is why I did not go that way. I have seen a much better design, but it just has not seen the light of day yet.

I am running a 12V mechanical pump, but any setup that requires or could require the use of 2 pumps seems silly to me. Why buy an aftermarket pump if you have to rely on the stocker for any use??

Just my thoughts.

The MITUSA is the updated version of the RASP, all deigned and R&D by the same group a guys.

DDT was doing the marketing for Opie, but Opie has since started his own site and is selling them through it. I tried to buy the pump through DDT but he was impossible to get a hold of, that's how I ended up with the pump from Rich. Would have rather bought the real one but had to have one to get the truck rollin again and time wasn't allowing me to wait for the other.

 

The story is told differently on the other end. But it's neither here nor there. They all have the same design.

3 of my buddys have air dogs they love it. 2 of them had fass before hand and said it was ok but there were a couple things they didnt like about. they also said air dogs has 1 or 2 parts in it system that fass doesnt to make it better ill try and find out more info.

 

I would go With Fass... My stepdad has one on his 01 dodge and it works great.... pluse when you get a aftermarket pump it reduces ur chance of your injector pump going out witch are about $1000 to $2000 But i dont know much about the other two listed

 

Ok guys I changed my Fuel filter today and that seemed to help a little. I think the old filter was clogged. I still have 7psi, it just doesn't dip as much.

I got ahold of Opie @ Intelligent Engineering. I told him I'm having a hard time finding somewhere that stock the Mitusa pump. He said that a lot of places don't stock them as there isn't much profit in them. I'm waiting on a reply but hopefully i'll be able to pick one up from him.

 

your workin on borrowed time at 7 psi get that thing fixed quick or your gonna be buying a new IP
