They only thing is you need a special fitting to go onto the schreader fiitting on the banjo bolt....can be hard to find in a short period of time in Canada....How quick do you need the truck up and running?

If you need some help finding the FP gauge parts, jsut let me know. I would be happy to help.

 

We really don't need the truck up and running by a certain date. If you could help me locate the pieces for a fuel pressure gauge I would greatly appreciate it! Because I really don't feel like spending $230 US for a gauge right now, even though they are worth it We do not have autozones in Canada, so we'll be taking the truck down to our local garage, or I might even ask my teacher at school if I can borrow it one night

Thanks

Dinner

 

I can help you out - no problem. Just let me get some info together....

 

Thanks, I'll be talking to my dad about all this stuff, and going to try and force him to buy this stuff

 

Ok, heres the deal dinner...

This is what the setup looks like:



You remove the plug on top of the fuel filter (just as shown in the pic) and hook up a temporary guage there. The connection is 1/8" npt...Its probably easiest just to use a 12-18" grease gun hose and get youself a 0-15 or 0-30 psi pressure guage [1/8" npt bottom mount style (it doesnt matter what kind)], and a 1/8" coupling.

I dont have any more pics but you will just have to screw the grease gun hose into the port in the pic and then attach your guage to the hose. This is a simple system just for testing and we can deal with a permanent guage after you get this figured out.

The best thing for you to do would be to scan it and check fuel pressure. Clear as mud??? Post away if you have any questions.

 

Does that help you out Dinner ??

 

Your VP may not be toast. Remain optimistic! If your FP doesn't supply your VP with fuel, then how could the VP squirt anything!
Do not even put a stock FP back on. Invest in an up grade! I love my Airdog but it was $600. There are many other fine options for less than $200.

 

Yup, thats why we are checking FP and scanning for codes.

 

I can get you guys lift pump fuel pressure gauges for less than $20 all day long!

.... and stainless steel to boot!!!

 

Thanks for the Pictures and list of supplies. Tonight I went out and just loosened the Banjo Bolt Coming from the Fuel Filter, into the VP a little bit. When I turned the key to just on, fuel was spraying out of there.

So what do you guys think. Should I still scan for codes, or are you pretty sure it's my VP?

Here is the set-up on my 99.
The gauge under the hood is reading the pressure between the lift pump and the filter (BLUE arrow).
The RED arrow is pointing to the test port that reads the pressure between the filter and the injection pump and this is where my inside dash gauge reads from.
You will want to connect your test gauge to the port closest to the center of the filter housing (the one the RED arrow is pointing to)
The hoses are grease gun extensions (a couple of dollars) and the gauge (0-30psi) was a freebie from work.

The first test gauge I made was a gauge off of an old air regulator,,,,, did the trick until I did the current set-up.

 

Sure sounds like the lift pump is OK,,,,,, and that means you should be getting BIG pressure out of a cracked injector line when you bleed it. If you're not,,,,,,, sure sounds like a bad VP-44. It still may be a good idea to scan for codes,,,,,,,, BUT it doesn't sound very promising for the injection pump.

Sorry,,,

 

I couldnt agree more with RATTLIRAM


Nice job BTW....

 

Dinner,

Couple of thoughts here, coming from one who has 12V experance and fluid dynamics experance. Please understand that while it's safety realted, i'mot trying to hinder, but help prevent an injury. IF you are going to be trying to see what kind of fuel flow you could be getting from a LP or VP-44, you need safety glasses (minimum) and need to keep clear of any path fuel could flow. Pressures like those suggested will penetrate your skin and can enter your bloodstream at a few thousand PSI. I've actually witnessed a co-worker who had his arm torn open by hydraulic oil at 1500 psi and at a 90* C operating temperature. Believe me, there are times to try your hand tinkering, and other times that it's best to take it in.

Good luck, I do hope it's the LP and not the VP-44.
