i called geno's today to order gages, they said they do not sell the isspro EV fuel pressure gage because its not reccomended for diesel. WHATS UP WITH THAT? so do i have to go with a whole different set? i wanted to use a mechanical gage.

 

They'd better be, as that's what I'm running, Diesel going right to the back of the guage.

I know Isspro's had a major backorder problem, but other than that.

I got mine from West Texas Diesel.

I think the problem Isspro was running into was their isolator, just don't use it.

 

I just checked out the West Texas site and didn't find an answer I was looking for. What is the pressure range of the Isspro EV fuel pressure gauge that you have mkubacak?? Are you using an isolator or straight to the gauge?

I have two other Isspros (boost and EGT), but I have a Westach electric fuel gauge. Obviously, it doesn't match so I'm interested in the range of the EV you guys have for fuel.

Oh, and how long have you had them in operation?

Thanks!

30psi ISSPRO EV, no isolator, 9 months, no leaks or problems. It even got pounded when the needle valve accidently got set wide open for a 500mi towing trip.

I have the 0 to 30 psi ISSPRO - over a year 10k+ miles no issolator no problems.

I understood it is rated for diesel when I purchased it - but did not independently verify that.

Guys, inside a pressure guage is a device called a bourdon tube. It is the pressure sensing device. The Bourdon tube is essentially a thin hollow tube made of metal and is directly connected to the pointer. So, I dont understand how they can say its not made for "diesel". To my knowledge, diesel isnt particularily harmful to metals. I think they were takling about the isolators....the diaphrams are not made for diesel applications and do not last when used with diesel.

 

Is the needle valve a must? Or can you get by with out it. I ran mine from the bottom of the filter straight to the guage using 1/4" stainless braided teflon hose. Anybody else use this set up.

 

The needle valve or a grease gun hose is a must....some guages only last a few hours without it.....you need to dampen the pulse from the VP-44.

 

you need to dampen the pulse from the VP-44.

hmmm would an air arrester work? the type used on household water systems for washing machines and dishwashers? one could easily be plumbed in to the fuel gage line to dampen any pulses.

 

My truck has rubber hose between VP and filter canister where I connected to. Would'nt this hose dampen the pulse.

 

I just made sure and left a bunch of air in the line. It comes straight off the bottom if the filter canister with a taped banjo bolt.

There is no noise or vibration of the gauge. It has soild smooth sweeps when the pressure drops on hard acceleration and when it comes back up.

 

Some 24 valve fp gauges pulsate, others don't. Some pulsate right away, others after any air in the line is displaced by diesel which always happens eventually. One thing's for sure though, pulsation will kill a electrical sender or mechanical gauge. Adding a $4 needle valve to the setup is cheap insurance.

An air arrester would work but would cost more and take up more space.

 

a pressure snubber will also work - but again, will cost more than the needle valve.
