Gauges and lift pump questions

[mosi3r]

I have a LMM that I have efi live for I know I need a boost and pyro gauge but what is a good third? Rail pressure or trans temp? Also looking into getting a airdog but I noticed(owned truck 2 months) that there is a inline electric pump under rear door. Will that need to be removed? Wanted to run the dual filter pump.

Sounds like you already have a lift pump

So I'm guessing I just remove it and put the airdog on? I don't know how old this pump is or what kind it is, all I know is when I bought the truck I noticed it had a slight leak where the pump was(lose fitting). It is kinda loud, thought it got louder after I changed my stock fuel filter.

If you already have a lift pump which are all pretty loud I would save the money and just add a filter setup. As for gauges I would go with a rail pressure over a trans, simply because you can check the trans in the cluster and you can't check the rail pressure.

Was leaning more towards rail pressure but I read that you can't trust the stock trans gauge so was looking for opinions.

Fuel pressure for lift pump pressure isn't a horrible idea either. Rail pressure will give you a code.

Can youtake a pic and post itof the lift pump if its a crappy 1 thats gonna take a shit in short order your better off replacing it IMO

Ill snap a picture tomorrow before work

 

[mosi3r]

Didn't get a chance to upload the pictures, will tomorrow. Basically the inline looks look a regular fuel filter (like on gassers) but with two wires going in it. Didn't see any name or logos.

I uploaded them to an album then posted the img code. Thoughts?

They are up now........get rid of that thing its no good.

 

[mosi3r]

Checked the album was marked wrong :screwy: I had a feeling it might have been crap, you'd laugh if you saw the wiring job :roflmao: What gph should I look at? I'm only running efi w/dsp5 highest tune is 150. Don't plan on any major upgrades for awhile (unfortunately)

150 gph and up,I run 150 and hold rail just fine.
