Hey guys- i have a 1988 chevy suburban 454 tbi. hope you guys dont mind me posting, but this is the best tbi forum out here..I know most of you guys use the rochester 220 unit, as opposed to the stock 700 unit. im having some fuel pressure problems, and i want to hook up a permanent gauge/adjustable regulator.

- Does anybody know the fitting size for the fuel inlet for the tbi220?
- Would an adjustable regulator even fit under that stupid housing?
- does a gauge fit with the stock air cleaner?

i'd like to see if anybody has done this and could offer some wisdom/part numbers. Thanks in advance! otherwise, i have to mount a gauge under the frame and that would be a pain in the ***. Thanks!

 

xtremefi has the AFPR and the guage adapter you need. Check out their ebay store at http://motors.search.ebay.com/_W0QQf...ssZxtremeQ2dfi

 

man you guys rock! thanks for your help!

 

What Fuel Pressure Gauge have you guys found that works with that gauge adapter? I found this one, but it's for Mustang's would it work?

How good are xtreme-fi's other products like their 305/350 TBI bored out to 50mm?
