carter fuel pump

I have the same set up--stock pump + Carter Pump & 22-25 psi.

I just replaced my vp44. The local Bosch Dealer did the work. I asked about the high pressure & he said it did not matter--the eccess fuel is returned to the tank. But all the same I would like to hear more about it.

propuller... pressure you have should be fine. Been running this type of pressure for over a year and half, 40,000 miles plus no problems.

propuller--I installed the carter lift pump shortly after I had the Banks system installed. Banks installed at 71k--pusher pump at 77k--vp44 problems at 90k--replaced vp44 at 100500 mi (last week) The total cost for a new vp44 with the latest upgrades(so they tell me) was $1554. 00. I have not hooked up the BANKS OTTOMIND yet--waiting to give the new pump a few weeks of break-in time.

Humm... I ordered a 7psi ...pusher

But I was under the impression that the pusher delivered the pressure to the factory lift pump and it wouldn't be straining as much to deliver its rated output of 15psi. I DIDN'T THINK THE PRESSURE WAS ADDITIVE 7+15 = 22?

Am I missing something here? I know there is controversy on the pusher, even the latest TDR mag has a thumbs down opinion... But I guess I was thinking it was the altering the fuel system/warranty thing... but now I find the "it will damage the VP44" comments or the i"t helps cool/lubricate the VP44 with bypass fuel" comments...

... I'm so confused

I guess I'll leave the pusher in the box, wait for my back ordered DiPricol gauges to show up, install them find out where I am at first. Then sort threw the opinions and make a decision and live with it. However as much as I like my truck I am annoyed with Dodge. why don't they evaluate this issue make a statement of what all the Dealer's will or will not do and why. Different people getting a different story from dealers just isn't good customer relations . Buy the way I called the dealer I bought my truck from in Golden Colorado and asked to come in and check my fuel pressure. The service rep told me it would cost me $200 If it tested good. His attitude was a little in your face on the phone. I'll be buying my own test gauge in addition to my in cab DiPricol. I won't be buying a $2 part from that dealership in the future.

fuel pressure

Jim -you can get a fuel injection pump test kit bt ATD part # 5567 (for about $ 35-$40 if I remember correctly) if you want to test the fuel pressure while waiting for your guages. This at least will give you a bse line to work from. The pressure will vary from idle to WOT. I do not know what stock specs are for a stock pump but I remember reading on TDR that 8 psi at WOT is a target pressure. Anything much less is a red flag. As far as DC coming clean about lift pump problems--I think it would be on the same line as their thermostat problems. --No problem until it fails !!! My thermostat was going bad & DC replaced it with the newest upgrade due to problems w/the stock part & the dealer said replacing the thermostat was a maintenance issue much like an oil change & therefore not covered under warranty! So somehow maybe the same is holding true with other parts--just an opinion!!

Jim--By the way--it is very easy to test your fuel pressure. The brass fitting on top of the fuel filter can be removed to allow access to install a test guage--permanent or temp.
