my friend gave me an autometer fuel pressure guage but it only goes up to 100 psi, where can i get a fuel pressure guage that will read more than 100 psi?also the one i just got can't be mounted inside the car so could i just use some sort of isolator for it or do i have to get the isolator from autometer? also will 36LB delphi style fuel injectors work on our motors(plug right in).. sorry for the noob questions but i did a search and could not find anything.thanks for ur help..

you shouldn't be running any more than 100psi. you dont want any more than 100 psi on your fuel system. thats gettin dangerous.
my advise is to get the electrical one. a mechanical gauge for FP is too much of a pain in the ass.
dont know about the injectors.

well i have the hahn stage 2 kit with front mount(7-8lb boost) and vortech fmu with the 12:1 disk, greddy typ-s,walbro intank(have not hooked up the inline yet)missing link,hrc black box,and stock everything else.. gonna do a motor rebuild soon and was concern about not being to keep an eye on fuel pressure above 10 lbs of boost.whast a good price on the electrical fuel pressure guage anyway?since were on the subject of fuel..i have the vortech fmu mounted in the back by the fuel tank,should i hook up the inline?or will the walbro be okay for stock injectors?the walbro seems to run fine so far,but if i do need to install the inline ..how should i run the fuel hose for the inline? one line to the fuel filter and the other to the intank?sorrie again for the noob questions but i lost the instructions.

1. get rid of the FMU.
2. get the S-FMU, they're pretty cheap on ebay.
3. dont worry about the inline, if its the walbro 255lph pump, your fine.
4. you dont need the HRC black box of shit, if you have the missing link.
5. DO NOT RUN 10 PSI ON STOCK INTERNALS. unless you hankering for a rebuild in a hurry.
6. get at least 30lbs injectors and ditch the stockers.
7. see # 5.

7. see # 5.

Just a reminder

If you buy bigger injectors and lower your peak fuel pressure, you can get away with using the Walbro 255 HP pump.

If you keep your stock injectors and keep your fuel pressures in the 100+ psi range, you'll want to put the inline pump in also. If you must run super high fuel pressures, you'll want the inline. Even the mighty Walbro 255 HP is marginal at 100+ psi.

I bet HRC would fax you a copy of the instructions if you asked nicely. There was also a person called "optimuspeterson" who had a link to scanned HRC instructions.
